Mendeliome v1.1884 MYZAP Zornitza Stark changed review comment from: 10 individuals from four unrelated families with bi-allelic variants in this gene with DCM. Supportive zebrafish model. Note the MYZAP and GCOM1 genes are part of the GRINL1A complex transcription unit. Some of the reported variants affect GCOM1 with postulated effect on MYZAP due to read through transcription (two families), and in the rest of the families MYZAP was affected directly.
Sources: Literature; to: 10 individuals from four unrelated families with bi-allelic variants in this gene with DCM. Supportive zebrafish model.

The MYZAP gene is part of the GRINL1A complex transcription unit (CTU), or GCOM1, which also includes the downstream POLR2M gene, or GRINL1A.. Some of the reported variants affect GCOM1 with postulated effect on MYZAP due to read through transcription (two families), and in the rest of the families MYZAP was affected directly.

Transcription from an upstream promoter within the GRINL1A CTU produces 2 types of alternatively spliced transcripts: MYZAP transcripts, also called GRINL1A upstream (GUP) transcripts, which include only exons from the MYZAP gene, and GRINL1A combined (GCOM) transcripts, which include exons from both the MYZAP gene and the downstream POLR2M gene. Transcription of the POLR2M gene initiates at a downstream promoter within the GRINL1A CTU and produces alternatively spliced POLR2M transcripts, also called GRINL1A downstream (GDOWN) transcripts, which include only exons from the POLR2M gene

Mendeliome v1.1840 PRRX1 Melanie Marty changed review comment from: > 17 individuals with Craniosynostosis from 14 families had been found to have rare heterozygous variants in PRRX1, loss of function variants (PTCs, start loss and partial/full gene del) or missense variants affecting the homeodomain.
> These consisted of three de novo variants, but for the majority of cases the variant was inherited from an unaffected parent, yielding an estimate for the penetrance of craniosynostosis of 12.5%.
> These results were also supported by immunofluorescence analyses which showed that missense variants within the PRRX1 homeodomain cause abnormal nuclear localisation (PMID: 37154149)
> Authors discuss how the previous reports of agnathia-otocephaly doesn't fit with this new evidence and they showed that a missense variant previously reported in a patient with agnathia-otocephaly p.(Phe113Leu) did not affect nuclear import.

Supporting evidence:
> Post-natal calvarial stem cells expressing Prrx1 have been shown to reside exclusively in the calvarial suture niche, suggesting a requirement for PRRX1 regarding suture patency during early development (PMID: 28366454)

>Prrx1 has been shown to be widely expressed within the mouse coronal suture (PMID: 34376651)

Review for gene: ATXN7L3 was set to GREEN
gene: ATXN7L3 was marked as current diagnostic
Added comment: This study reports 9 unrelated individuals with de novo heterozygous variants in ATXN7L3 identified through WES testing and GeneMatcher. Core clinical features included: global motor and language developmental delay, hypotonia, and dysmorphic features (hypertelorism, epicanthal folds, blepharoptosis, small nose, small mouth, and low-set posteriorly rotated ears). Variable features included: feeding difficulties, seizures, mild periventricular leukomalacia, and structural cardiac abnormalities.

A recurrent nonsense variant [p.(Arg114Ter)] was found in 5/9 individuals. The other variants were 1 frameshift [p.(Ser112LysfsTer12)] and 3 missense variants [p.(Ile71Thr), p.(Ser92Arg), and p.(Leu106Pro)]. They investigated the effects of the recurrent nonsense variant [p.(Arg114Ter)] in fibroblasts of an affected individual. ATXN7L3 protein levels were reduced, and deubiquitylation was impaired (as indicated by an increase in histone H2Bub1 levels). This is consistent with the previous observation of increased H2Bub1 levels in Atxn7l3-null mouse embryos, which have developmental delay and embryonic lethality.

Pathogenic variants in deubiquitinating enzymes (DUBs) have been implicated in neurodevelopmental disorders (ND) and congenital abnormalities. ATXN7L3 is a component of the DUB module of the SAGA complex, and two other related DUB modules, and serves as an obligate adaptor protein of 3 ubiquitin-specific proteases (USP22, USP27X or USP51).

Added comment: 8 individuals from 6 families with core features of amelogenesis imperfecta and sensorineural hearing loss. Intellectual disability, ocular disease, ear developmental abnormalities and lymphoedema were also present in multiple cases. WES and WGS identified biallelic pathogenic variants in PLXNB2 (missense, nonsense, splice and a multiexon deletion variants). Variants segregated with disease.

PLXNB2 is a large transmembrane semaphorin receptor protein, and semaphorin-plexin signalling controls cellular interactions that are critical during development as well as in adult life stages. Plxnb2 expression was detected in differentiating ameloblasts in mice. Human phenotype overlaps with that seen in Plxnb2 knockout mice.

gene: CEP295 was marked as current diagnostic
Added comment: 4 children from 2 unrelated families with Seckel-like syndrome - severe primary microcephaly, short stature, developmental delay, intellectual disability, facial deformities, and abnormalities of fingers and toes. WES identified biallelic pathogenic variants in CEP295 gene (p(Q544∗) and p(R1520∗); p(R55Efs∗49) and p(P562L)).

Patient-derived fibroblasts and CEP295-depleted U2OS and RPE1 cells were used to clarify the underlying mechanisms. Depletion of CEP295 resulted in a decrease in the numbers of centrioles and centrosomes and triggered p53-dependent G1 cell cycle arrest. Loss of CEP295 caused extensive primary ciliary defects in both patient-derived fibroblasts and RPE1 cells. The results from complementary experiments revealed that the wild-type CEP295, but not the mutant protein, can correct the developmental defects of the centrosome/centriole and cilia in the patient-derived skin fibroblasts.

Added comment: PMID 35066879: 3 fetuses from 2 different branches of a consanguineous family, presenting with distal arthrogryposis, underdevelopment of the corpus callosum, and dysmorphic facial features. Exome sequencing identified a biallelic 4-bp deletion (c.233_236delTTCC; p.Leu78Glnfs*11) in USP14, and sequencing of family members showed segregation with the phenotype. Ubiquitin-specific protease 14 (USP14) encodes a major proteasome-associated deubiquitinating enzyme with an established dual role as an inhibitor and an activator of proteolysis, maintaining protein homeostasis. Usp14-deficient mice show a phenotype similar to lethal human multiple congenital contractures phenotypes, with callosal anomalies, muscle wasting, and early lethality, attributed to neuromuscular junction defects due to decreased monomeric ubiquitin pool. RT-qPCR experiment in an unaffected heterozygote revealed that mutant USP14 was expressed, indicating that abnormal transcript escapes nonsense-mediated mRNA decay.

PMID 38469793: biallelic USP14 variants in four individuals from three unrelated families: one fetus, a newborn with a syndromic NDD, and two siblings affected by a progressive neurological disease. Specifically, the two siblings from the latter family carried two compound heterozygous variants c.8T>C p.(Leu3Pro) and c.988C>T p.(Arg330*), while the fetus had a homozygous frameshift c.899_902del p.(Lys300Serfs*24) variant and the newborn patient harbored a homozygous frameshift c.233_236del p.(Leu78Glnfs*11) variant.

1 family with an atypical inherited bleeding disorder characterised by severe spontaneous bleeding episodes in childhood and microcirculatory problems. 4 affected individuals across 2 generations have R49*in APOLD1, another affected individual from a third generation was not able to be sequenced = 4 meiosis. 4 unaffected individuals did not have the variant.

This gene has no NMD region, R49* would affect 82% of the protein. Paper is not using the MANE select transcript, alt p. in MANE select is R18* which affects 92% of the MANE select protein

Interestingly R49* is created by a delins/2 missense in cis, 1 common R49Q and 1 rare R49W, some UNaffected family members just have the common missense without the other in cis.

Immunofluorescence studies in patient platelets showed a 50% reduction of APOLD1 and disrupted cytoskeletal and junctional organization.

SiRNA silencing of APOLD1 in HBDEC cells resulted in altered cell shape and size, and were associated with endothelial cell junction dismantling. These cells were also almost devoid of VWF.

Review for gene: TUBA4A was set to AMBER
Added comment: One novel TUBA4A variant in two unrelated Chinese patients with sporadic congenital myopathy.

Identified candidate genes using laser capture micro dissection, proteomics, WES, clinical data, myopathological changes, electrophysiological exams and thigh muscle MRIs.

The variant is de novo in both patients, c.679C>T, p.(Leu227Phe). The prominent myopathological changes in both patients were muscle fibres with focal myofibrillar disorganisation and rimmed vacuoles. Immunofluorescence showed ubiqution-positive TUBA4A protein aggregates in the muscle fibres with rimmed vacuoles. Overexpression of Leu227Phe resulted in cytoplasmic aggregates which colocalised with ubiquitin in cellular model.

Patient 1 is 14yo and had delayed motor development milestones since infancy. Myopathic face, high-arched palate, waddling gait, winged scapula and muscle weakness in four limbs with lower extremities and proximal muscle more severely affected. Follow up at 14yo showed slight improvement in motor function compared with 3yo.

Patient 2 is 6yo and presented with motor retardation since birth. At 3yo, presented with mild ptosis and ophthalmoparesis, high-arched palate and muscle weakness involving both proximal and distal in all limbs.

No likely pathogenic variants in 116 other protein-encoding genes. Variants confirmed by Sanger sequencing and absent from gnomAD. ACMG predicts likely pathogenic classification.

Added comment: 5 unrelated families reported with recessively inherited cerebral small vessel disease had compound hetereozygous or homozygous variants in NIT1. 1 family (3 siblings) had p.(Ala68*) in trans with p.(Arg243Trp), the remaining 4 families (1 individual each) were all homozygous for p.(Arg243Trp).

Patients presented in mid-adulthood with progressive movement disorders (e.g. dystonia, chorea, bradykinesia and tremor, gait disturbance, dysarthria) and had abnormal brain MRI findings (honeycomb appearance of the basal ganglia-thalamus complex, due to numerous strongly dilated PVS). 3 patients had non-lobar intracerebral hemorrhage. Slowly progressive cognitive decline was also a key feature.

Metabolic analysis in urine confirmed loss of NIT1 enzymatic function.

Note p.(Arg243Trp) has 1 homozygote in gnomAD v4, but permitted due to later presentation in reported patients.

Added comment: In a cohort of 1,201 men from China with oligozoospermia and azoospermia, hemizygous RHOXF1 variants were identified in 4 unrelated individuals.

Three of these variants were missense variants (V130M, A91V & A156V), all were absent from gnomAD (including version 4) and had deleterious in silicos.

The one other variant was a nonsense variant (R160X) which is predicted to escape NMD and truncate the protein. This is seen in gnomAD version 4 in 1 heterozygote female, and absent in other versions.

In vitro functional evidence for these variants was provided, the V130M, A156V and R160X mutants demonstrated impaired protein localisation with an increase in the protein in the cytoplasm and impaired nuclear entry, the A91V mutant protein did not share these localisation defects.

Further, The V130M mutant protein decreased DMRT1 promotor activity, DMRT1 is considered essential for testicular development and spermatogenesis. However, the R160X variant demonstrated increased activation, three times higher than WT. The two other missense variants had no effect.

Added comment: 11 male patients with 6 missense and 1 nonsense variant in WDR44 displaying a wide range of cognitive impairment and variable congenital anomalies associated with primary cilium dysfunction. All patients had learning difficulties with 8 labelled as intellectually disabled (mild-moderate). Other clinical features included anomalies of craniofacial, musculoskeletal, brain, renal and cardiac development.
WDR44 is a negative regulator of ciliogenesis. Increased binding is hypothesised to underlie the pathogenicity of WDR44 variants identified in this cohort. Functional data supported impaired ciliogenesis initiation in patient fibroblasts and a zebrafish model. A zebrafish model recapitulated the human phenotype when morphants expressed WDR44 L668S, D669N, S764F, G782C, H839R, and R733* variants. Of note, D648G or N840S did not recapitulate the phenotype in the zebrafish model.
The studies supported a GoF mechanism, but the authors could not rule out that LoF of WDR44 contributes to the ciliopathy-like phenotype observed, because protein expression data was only available for a limited number of patients.

She had mild intellectual delay and clinical features of a congenital, nonprogressive myopathy with moderate proximal and distal weakness. X-rays showed skeletal dysplasia, including cervical thoracic scoliosis and lumbar scoliosis. She was reported as having had weakness at birth with poor suck, micrognathia, hypotonia, and talipes. She was documented to have significant motor delay as a child. MRI of the brain demonstrated large posterior fossa CSF spaces.

Biallelic SOX8 variants biallelic (NM_014587.3:c.422+5G>C; c.583dup p.(His195ProfsTer11)) were identified by WGS. The +5 variant was shown to affect splicing, while the frameshift variant resulted in production of low-level truncated protein (not NMD predicted). Functional studies on patient fibroblasts showed misregulation of downstream SOX8 targets.

Zebrafish KO of the orthologous brocs8 causes decreased brain and eye size, neuromuscular anomalies and impaired locomotion, recapitulating some of the key traits of the human disease.

Added comment: PMID: 37981762:
- In one family, chet missense p.His638Tyr and p.Asn1917Ser segregated with microcephaly, short stature, limb-extremity dysplasia, and reduced testicular size in two affected siblings. Both sibs also fulfilled dx for mosaic variegated aneuploidy (MVA) syndrome and have tetraploidy.
- A lower but substantial proportion of MVA/tetraploidy cells was observed in II-1, II-2, and II-4 (who are het for one of the variants).

- In the same family, each variants in heterozygous state segregated with infertility and/or reduced testicular size in the proband’s father and maternal uncle.
- Variant screening of CEP192 coding regions performed for 1264 unrelated males with idiopathic infertility.
- Asn1917Ser was also detected in three additional unrelated infertile males with reduced testicular volumes.
- Two other missense and two synonymous variants were repeatedly detected in infertile males.

- qPCR showed CEP192 expression was decreased in individuals with c.1912C>T His638Tyr, mini-gene assay showed that c.1912C>T His638Tyr led to the skipping of exon 14, predicted to result in NMD.
- Epithelial cells cultured in vitro from patients with biallelic variants showed the number of cells arrested during the prophase increased because of the failure of spindle formation.

- Embyronic mouse lethality in Cep192-/- (hom for His638Tyr), Cep192M/M (hom for Asn1917Ser) and Cep192-/M (chet).
- Embryos of Cep192M/M mice had significant increase of MVA and tetraploidy cells.
- Number of apoptotic cells increased in Cep192M/M embryos compared with that of Cep192+/+, similar result in Cep192-/- embryos.
- Male mice with Cep192 heterozygous variants replicated infertility

Conclusions:
- Association of this gene with autosomal recessive disease has not been established.
- Association of monoallelic variants in this gene with infertility is not well established:
- Two variants with some supportive evidence from mouse model.

Added comment: Missense variant, c.604T>C; p.Phe202Leu, identified in two siblings with childhood-onset neurodevelopmental disorder characterised by global developmental delay, intellectual disability, behavioural abnormalities, and dysmorphic features. The variant is located in the catalytic domain of the kinase, and is inherited from unaffected mosaic mother.

Functional investigation revealed that the variant results in a gain-of-function in the ability of MARK4 to phosphorylate tau and leads to up-regulation of the mTORC1 pathway.

- 13 patients from 8 families of Ashkenazi Jewish origin all had the same homozygous frameshift variant (c.981dup). Predicted to cause NMD. The variant co-segregated with disease in all available family members. The affected individuals displayed mild global developmental delay and mild to moderate intellectual disability. Additional prevalent phenotypes observed included hypotonia, behavioural challenges and short stature. Considered a founder variant (1 in 52 Ashkenazi Jews carry the variant). Also present in other populations but no homozygotes in gnomAD.

Inherited optic neuropathies cohort from france with nothing found in OPA1, OPA3 and WFS1 or mtDNA. 2 individuals (55 and 47yo) found to have missense variant in MIEF1, p.Arg146Trp has 35 hets 0 homs in gnomad, p.Tyr240Asn is absent. Both have non-syndromic late onset inherited optic neuropathies characterized by initial loss of peripheral visual fields.

Functional studies in HeLa cells- both missense localised to the mitochondria and formed oligomers similar to WT. MIEF1 normally regulates mitochondrial fission dynamics and causes an increase in mitochondrial fusion events, however both missense variants caused a significantly decreased mitochondrial fusion events.

Phenotypes for gene: CFAP20 were set to Retinitis pigmentosa (MONDO:0019200)
Review for gene: CFAP20 was set to GREEN
Added comment: CFAP20 is a ciliopathy candidate. Demonstrate in zebrafish that cfap20 is required for motile cilia function, and in C. elegans, CFAP-20 maintains the structural integrity of non-motile cilia inner junctions, influencing sensory-dependent signalling and development.

Human patients and zebrafish with CFAP20 mutations both exhibit retinal dystrophy (retinitis pigments). Hence, CFAP20 functions within a structural./functional hub centred on the inner junction that is shared between motile and non-motile cilia, and is distinct from other ciliopathy-associaetd domains or macromolecular complexes.

Describe 8 individuals from 4 independent families with damaging biallelic variants (homozygous or compound heterozygous) in CFAP20 that segregate with retinal dystrophy. All variants cluster to one side of the protein, with two of the residues directly contacting alpha-tubullin.

Family 1 - consanguineous set of 3 siblings from Sudan, homozygous for CFAP20 c.305G>A; p.Arg102His (they also had a homozygous variant in DYNC1LI2 however CFAP20 was considered the better candidate.
Family 2 - 3 siblings from Spain, 2 with retinal dystrophy, 1 genetically tested and has c.337C>T; p.(Arg113Trp) and c.397delC; p.(Gln133Serfs*5)
Family 3 - single affected family member compound het for c.164+1G>A and c.457A>G; p.(Arg153Gly).
Family 4 - 3 affected siblings with generalised retinopathy and variable neurological deficits with c.164+1G>A and c.257G>A; p.(Tyr86Cys)

For all families, no individuals had signs of polycystic kidney disease; however, not all individuals had kidney imaging. Visual defecit phenotype presented between adolescence and adulthood (17-56 years old).

Used HEK293T cell expression studies to demonstrate a statistically significant decline of mutated CFAP20 protein levels (with the exception of p.Arg102His). To test the specific variants, they used the C.elegans orthologues.

MODERATE by ClinGen. TET2 was first reported in relation to autosomal dominant pulmonary arterial hypertension (PAH) in 2020 (Potus et al., PMID: 32192357). Out of a cohort of 2572 cases from the PAH biobank, 6 rare predicted deleterious likely germline variants including missense, nonsense, and frameshift variants were identified in 6 unrelated individuals. The relationship between TET2 and PAH is also supported by experimental evidence including tissue expression in controls and patients, biochemical function as a negative regulator of a proinflammatory response, and knock out TET2 mice exhibiting a PH phenotype.; to: Association with PAH:

Cohort of patients with an MRI based diagnosis of megalencephalic leukoencephalopathy with subcortical cysts (MLC). Missense variant in AQP4 seen homozygous in 2 siblings and het in the parents. Patients had macrocephaly, developmental delay, hypotonia, epilepsy, and cognitive deficit.

Western blots on generated MDCK cell lines showed no detectable expression of AQP4 protein from the cells with the patients variant. Immunofluorescence also showed no membrane expression. Overexpression studies in HEK293T cells showed WT was seen as mainly monomers or dimers where as variant protein formed large aggregates- likely due to the saturation of protein degradation pathways because of the overexpression.

Added comment: Wang et al. screened a large cohort of more than 600 CP patients from China and found several variants in TEP1, 11 of which were LoF, while no LoF variant was found in the control cohort. These children all had spastic CP. Among these 11 children, 6 children had birth asphyxia and neonatal encephalopathy. Compared to the total group with birth asphyxia (71/667), 6 patients with TEP1 LOF mutations had a significantly greater risk of birth asphyxia. They confirmed TEP1 as a risk factor for CP by cytological and animal models.

Uncertain if these are risk alleles vs indicative of a monogenic disorder. Note LoF variants in gnomad. As this was a cohort study, inheritance of these variants is unknown.

Added comment: 2 families with 4 affected individuals with Oral-facial-digital (OFD) phenotype. Homozygosity mapping and WES found 2 homozygous variants in INTS13 gene. This is a subunit of the Integrator complex, which associates with RNA Polymerase II and cleaves nascent RNA to modulate gene expression. Variants segregated with disease. Depletion of INTS13 disrupts ciliogenesis in human cultured cells and causes dysregulation of a broad collection of ciliary genes. Knockdown in Xenopus embryos leads to motile cilia anomalies.

WES identified recurrent de novo variant (p.Ser470Phe) in DCAF15 gene. This mediates ubiquitination and degradation of target proteins, and interacts with cohesin complex members (SMC1/SMC3).

Protein analysis from individuals showed increased accumulation of ubiquitination-modified proteins and SM3 (GOF mechanism). EpiSign analysis showed same DNA methylation pattern as other CdLS cases/genes. Zebrafish model showed reduced body length, reduced head size, reduced oligodendrocytes, heart defect, aberrant motor neurons, and abnormal response to visual/auditory stimuli.

NAA60 catalyses N-terminal acetylation of transmembrane proteins and localises to Golgi apparatus. In vitro assay of variants showed reduced capacity of Nt acetylation. Fibroblast studies showed significantly reduced levels of phosphate importer (SLC20A2). Loss of function variants in SLC20A2 (~50% of PFBC cases) lead to increased extracellular phosphate (which is thought to lead to calcium deposits in brain).

Added comment: PMID: 37308312; Alqahtani, MA. et al. (2023) Clin Genet. doi: 10.1111/cge.14389.
Three siblings in one consanguineous Saudi Arabian family with non-syndromic neonatal diabetes, all with a homozygous frameshift variant, NM_001321425.2:c.1448dupA, p.(Tyr483*), in ZNF808. (Same nucleotide and amino acid numbering as for the MANE SELECT transcript, NM_001039886.4).
This variant has been entered as likely pathogenic in ClinVar by this group.
This variant occurs in the last exon of the gene and is therefore not NMD-predicted. Instead it is predicted to cause a truncated protein.
This paper shows a diagram with several other truncating variants in this exon, which were reported in the paper by De Franco, E. et al. (2021).
(These patients also had low vitamin D levels, suggesting an association, and is consistent with other studies looking into loci that are associated with vitamin D).

De Franco, E. et al. (2021) medRxiv 08.23.21262262. (Exeter, UK):
Firstly, this group found a homozygous variant NM_001039886.3:c.637del, p.(Leu213*) that is predicted to cause a truncated protein, and also a homozygous CNV Chr19(GRCh37):g.53057128_53100968del (predicted to cause a deletion of exons 4 and 5) in two unrelated affected individuals. These patients had pancreatic agenesis, defined as insulin-dependent diabetes in the first 6 months of life (neonatal diabetes) and exocrine pancreatic insufficiency. Both were from consanguineous families. Parents were subsequently tested and shown to be heterozygous carriers.
They then investigated 232 additional patients who had been diagnosed with neonatal diabetes before the age of 6 months and found ten more homozygous ZNF808 variants. Six were nonsense: p.(Gln194*), p.(Cys233*), p.(Tyr427*), p.(Lys458*), p.(Tyr528*) and p.(Arg727*), and three were frameshift variants: p.(Ala379Valfs*157), p.(Leu588Profs*118), p.(Asn770Ilefs*98) and one was a whole-gene deletion.
All the frameshift and nonsense variants occurred in the last exon of the gene, which contains all 23 zinc finger domains; and therefore all of these variants are predicted to result in truncated proteins, and removal of some, if not all, those domains.
This group also carried out functional studies using an in vitro model of pancreas development and showed an aberrant activation of many transposable elements (mostly MER11 elements) that would be normally be repressed during early pancreas development.

Added comment: One consanguineous family, 4x individuals homozygous NM_015420.7(DCAF13)c.907 G > A; p.(Asp303Asn) (3x via WES and 1x via Sanger) with a neuromuscular disorder characterized by a waddling gait, limb deformities, muscular weakness and facial palsy.

In silicos analysis of mutant DCAF13 suggests that the amino acid change is deleterious and affects a ß-hairpin turn, within a WD40 domain of the protein which may decrease protein stability. Functional studies were not performed.

Previously, a heterozygous variant in DCAF13 with or without a heterozygous missense variant in CCN3, was suggested to cause inherited cortical myoclonic tremor with epilepsy. In addition, a heterozygous DCAF13 variant has been associated with autism spectrum disorder.

Added comment: Oral-facial-digital syndromes (OFDS) are a group of clinically and genetically heterogenous disorders characterised by defects in the development of the face and oral cavity along with digit anomalies. Pathogenic variants in >20 genes encoding ciliary proteins have been found to cause OFDS.

Identified by WES biallelic missense variants in a novel disease-causing ciliary gene RAB34 in four individuals from three unrelated families (aided by GeneMatcher).

Affected individuals presented a novel form of OFDS accompanied by cardiac, cerebral, skeletal (eg. Shortening of long bones), and anorectal defects.

RAB34 encodes a member of the Lab GTPase superfamily and was recently identified as a key mediator of ciliary membrane formation. Protein products of pathogenic variants clustered near the RAB34 C-terminus exhibit a strong loss of function.

Onset is prenatal (multiple developmental defects including short femur, polydactyly, heart malformations, kidney malformations, brain malformations), resulting in medical termination for three probands.

In the fourth, the only one alive at birth, proband born at 39+5 weeks, normal growth parameters after pregnancy with polyhydramnios, corpus callosum agenesis and polydactyly. Respiratory distress at birth.

All four probands presented typical features of ciliopathy disorders, overlapping with oral, facial and digital abnormalities.

All with homozygous missense variants. All absent in gnomAD (in homozygous state). Sanger sequencing confirmed mode of inheritance.

Added comment: PMID: 37403762- 6 patients with RPH3A variant. All 6 have ID, 4 have epilepsy, 2 with obesity, 1 with dysmorphic features. All 6 have missense variants, 3 shown to be de novo, the other 3 parents were not available for testing. I patient also had language and motor impairment, breathing issues and mixed hypo/hypertonia- he also had variants in CUL4B, PRKAG2, SCN4A, none of these genes cause seizures (which he had).

Patch clamp studies on 2 of the missense showed they increased either the number of NMDA receptors on neuron membrane surface or increased their conductance. Study suggests that the variants interrupt the normal role of RPH3A activity at the synaptic NMDAR complex which is needed for the induction of synaptic plasticity and NMDAR-dependant behaviours

Previously this gene was reported in PMID: 29441694- 1 girl with learning disabilities, tremors, ataxia, hyperglycemia and muscle fatigability. Chet for 2 RPH3A missense. Functional analysis showed strong and marginal impairment of protein binding for each variant. this is the only biallelic report currently.

- Bilateral coloboma and rod-cone dystrophy with or without cataract in nine individuals of a five-generation family.
- Heterozygous n.37C>T segregates with the disease in all affected individuals.
- Functional analysis including transcriptome analysis showed this variant resulted in significant alterations of miR-204 targeting capabilities. In vivo injection, in medaka fish (Oryzias latipes), of the mutated miR-204 caused a phenotype consistent with that observed in the family.
- Authors suggested gain of function is the likely disease mechanism.

PMID: 37321975
- Four members of a three-generation family with early-onset chorioretinal dystrophy, heterozygous for n.37C>T.
- Additionally, four family members were shown to be affected by albinism resulting from biallelic pathogenic OCA2 variants.
- Haplotype analysis excluded relatedness with the family reported in PMID: 26056285.
- In silico analysis of the MIR204 n.37C>T variant reveals profound changes to its target mRNAs and suggests a gain-of-function mechanism of miR 204 variant.

All variants absent in gnomAD and v2 pLI score for UNC79 is 1.

Patients with UNC79 variants were identified through GeneMatcher or an international network of Epilepsy and Genetics departments. x1 patient underwent duo exome sequencing, remaining had trio exome sequencing - no other causative variants identified.

Phenotypic features included:
- 4/6 autistic features
- 5/6 patients mild-moderate ID
- 4/6 behavioural issues (aggression, stereotypies)
- 4/6 epilepsy (focal to bilateral tonic-clonic seizures)
- 5/6 hypotonia

unc79 knockdown drosophila flies exhibited significantly higher rate of seizure-like behaviour than controls. unc79 haploinsufficiency shown to lead to significant reduction in protein levels of both unc79 and unc80 in mouse brains. Unc79 haploinsufficiency associated with deficiency in hippocampal-dependent learning and memory in mice.

Authors have reviewed their own evidence in relation to the gene-disease criteria detailed by Strande et al 2017 and note that their clinical and experimental data provides moderate-level evidence supporting the association between UNC79 and a neurodevelopment disorder including ASD.

Amber association favoured due to clinical phenotypic range reported between affected individuals and their lack of specificity.

The variant is absent from gnomAD, highly conserved, major grantham score (125) and is located in the hormone receptor domain (DECIPHER).

Both individuals had severe craniosynostosis (sagittal or bicoronal).

Other shared phenotypic features included:
- Limb anomalies (rocker-bottom feet, bowing of the legs, and short upper/lower limbs)
- Additional craniofacial manifestations(microtia, conductive hearing loss, ankyloglossia, esotropia, hypoplastic
nasal bones, and oligodontia)
- Other additional anomalies included renal dysplasia with cysts, tracheomalacia, pulmonary arterial hypertension, developmental delays, hypotonia, cryptorchidism, seizures and adrenal insufficiency.

Eight families with truncating variants affecting the same stretch of cytosines in this gene.

In the 100KGP discovery cohort, in three families with Familial thoracic aortic aneurysm disease (FTAAD) of European ancestry, the variant found was an insertion of a cytosine within a seven-cytosine stretch in the last exon, predicted to cause p.(S209Qfs*3). This variant was also identified independently in eight affected members of three pedigrees of Japanese ancestry in a separate Japanese patient group.
Also, this study found a deletion of one of those cytosines causing p.(S209Afs*61), in one individual or family.
Also, there was one family in Belgium in which the affected members carried a 5-bp deletion in the same stretch of polycytosines inducing a frameshift p.(P207Qfs*3).

Phenotypic analysis of the individuals suggest that the phenotype of these FTAAD individuals and families is more like Loeys-Dietz syndrome.

Added comment: 2 patients from reportedly unrelated consanguineous Moroccan families with the same homozygous frameshift variant reported with late-onset retinal degeneration. Patient 1 was diagnosed with RP at age 60, patient 2 at age 69. Both reported loss of visual acuity in the years prior.

Immunoblotting of cell lysates from patient fibroblasts showed that some mutant transcript escaped NMD. Functional testing showed that the truncated protein could bind microtubules but was unable to associate with centrioles or its interaction partner CEP290. Patient fibroblasts were shown to have delayed ciliation.

Mutant protein was unable to rescue loss of cilia in CEP162 knockdown mice supporting that the mutant protein does not retain any ciliary function, however additional data supported that the truncated protein was able to bind microtubules and function normally during neuroretinal development. The authors suggest this likely underlies the late-onset RP in both patients.

Rated Amber because only a single variant has been reported in patients who may or may not be related (same ethnic background).

Added comment: Two unrelated cases with monoallelic variants in DPYSL2/ CRMP2, supported by functional studies. However, the evidence is not sufficient for green rating as there are variants reported in other (but different) genes in the two patients.

PMID:35861646 reported two cases identified with heterozygous variants (patient1: c.1693C>T (p.Arg565Cys); patient 2: c.42C>A (p.Ser14Arg). These patients had overlapping phenotypes including dysmorphic features, severe global developmental delay and hypoplasia of the corpus callosum. In addition, patient 2 was bed-ridden and could not roll out and had a history of myoclonic seizures and status epilepticus.

It should be noted that patient 1 is compound heterozygous for 2 missense variants in the EFCAB5 gene and was hemizygous for a maternally inherited missense variant in the GPKOW gene and patient 2 had 1 de novo missense variant in the COBLL1 gene and was compound heterozygous for 2 missense variants in the POTEF gene. The severity of the phenotypes between the two cases differs significantly and the additional variants may have possibly contributed to this phenotype.

Brain-specific Crmp2 knockout mice display neuronal development deficits and behavioural impairments associated with hypoplasia of the corpus callosum. In addition, functional studies performed in zebrafish and cell lines that the CRMP2 variants lead to the loss-of-function of CRMP2 protein and can cause intellectual disability.

PMID:29784638 reported three siblings with homozygous variant c.289G>C (p.Gly97Arg) in RBSN. The proband presented global developmental delay, had complete 46,XY male-to-female sex reversal and died at age 20 months after multiple infections. The other 2 affected siblings underwent unrelated-donor bone marrow or stem cell transplantation at 8 and 6.5 months of age, respectively. Both have severe intellectual disability and are nonambulatory and nonverbal.

PMID:35652444 reported two unrelated families (three siblings from a family of Iranian descent identified with homozygous variant c.547G>A (p.Gly183Arg) and four members from a family of indigenous Cree descent identified with homozygous variant c.538C>G (p.Arg180Gly)) with overlapping phenotypes including developmental delay, intellectual disability, distal motor axonal neuropathy and facial dysmorphism.

Mendeliome v1.711 EPHA10 Achchuthan Shanmugasundram changed review comment from: Comment on rating: This gene should be rated RED as this gene has been associated with post-lingual autosomal dominant non-syndromic hearing loss from a single family, and supported by functional studies.

PMID:36048850 reported the identification of a heterozygous non-coding variant c.-81_-73delinsAGC cosegregating with hearing loss. Although variants have been identified in KIF17 and USP48 in several members of this family, they did not cosegregate with hearing loss. One affected member of this family had an ideal hearing restoration after cochlear implantation.

Epha10 was expressed in mouse cochlea at both transcription and translation levels. In addition, EPHA10 mRNA was detected upregulated in patients compared with controls by qRT-PCR. Overexpression of Eph (the homolog of human EPHA10) altered the structure and function of chordotonal organ (equivalent to mammalian auditory organs) in fly model. These functional evidence suggests that 'gain of function' may be responsible for the hearing loss phenotype.

This gene has not yet been associated with any phenotypes in OMIM or Gene2Phenotype.

A four years old girl was identified with a novel homozygous missense variant (c.233A > G, p.Lys78Arg) in OXR1 gene and was reported with sensorineural hearing loss.

Functional studies in zebrafish model showed that the ortholog orx1b gene is expressed in the statoacoustic ganglion (SAG, a sensory ganglion of ear) and posterior lateral line ganglion (pLL). In addition, knockdown of oxr1b resulted in a significant developmental defect of SAG and pLL and this phenotype was rescued by co-injection of wild-type human OXR1 mRNAs, but not mutant OXR1 (c.233A > G) mRNAs.; to: Comment on gene rating: This gene should be rated AMBER as there is one case and supportive functional data to associate OXR1 with hearing loss.

Added comment: Comment on classification of gene: This gene should be rated amber as it has been implicated in inflammatory poikiloderma with hair abnormalities and acral keratoses as identified from two unrelated families harbouring the same biallelic variant and supported by functional studies.

PMID:34999892 reported four UK women of South Asian origin (three Pakistani sisters and an unrelated Indian woman) identified with homozygous variant c.503A>G, (p.Asn168Ser) and presented with poikiloderma, hair abnormalities, and acral keratoses, which the authors named as inflammatory poikiloderma with hair abnormalities and acral keratoses (IPHAK).

Both in silico modelling and splicing assays from a patient sample showed that this variant is responsible for splicing defects and defects in LTV1 alter the export of nascent ribosomal subunits to the cytoplasm in yeast.

This gene has already been associated with relevant phenotype (MIM #620199) in OMIM, but not in Gene2Phenotype.

Added comment: Comment on gene classification: The rating of this gene can be added as green as this gene has been implicated in early-onset osteoporosis from three unrelated cases and was supported by evidence from functional studies. All three patients harboured heterozygous variants in WNT11 gene.

Three unrelated cases are reported in PMID: 34875064. A four year-old boy harbouring de novo heterozygous loss-of-function variant c.677_678dupGG (p.Leu227Glyfs*22) was reported with low BMD, osteopenia and several fractures.

A 51 year-old woman and her 69 year-old mother were identified with a heterozygous missense variant c.217G>A (p.Ala73Thr). The woman was reported with bone fragility, several fractures, osteoarthritis and osteoporosis, while her mother also had several osteoporotic fractures.

A 61 year-old woman that was reported with lumbar spine osteoarthritis had several fractures since 55 years of age was identified with a heterozygous missense variant c.865G>A (p.Val289Met).

This was also supported by results from functional studies, where cell lines with the loss-of-function variant generated by CRISPR-Cas9 showed reduced cell proliferation and osteoblast differentiation in comparison to wild-type. The expression of genes in the Wnt canonical and non-canonical pathways was inhibited in these mutant cells.

This gene has not yet been reported with any phenotypes either in OMIM or in G2P.

Unaffected sibling was heterozygous for maternal allele. Western blotting demonstrated reduced protein expression. Knockout of asna1 in zebrafish mode resulted in cardiac defects and early lethality. The Asna1 knockout mice displayed early embryonic lethality, consistent with a role of Asna1 in early embryonic development.

Added comment: Three unrelated individuals with common neurological features of developmental delay, progressive motor impairment, progressive lower extremity spasticity, and epileptiform activity or seizures. Other additional features varied.

Two of the individuals had the same de-novo missense, Thr51Ile, while the third was homozygous for a late truncating variant, Gln58AlafsTer10. The patient with the hom variant was described as less severe.

Functional studies in fibroblasts showed dysregulation of the sphingolipid (SL) synthesis pathway, showing that both variants impair ORMDL regulation of the pathway leading to various levels of increased SL. Over expression of human SPTSSA was shown to lead to motor development in flies, rescued by expression of ORMDL for WT SPTSSA but not mutant SPTSSA.

The de-novo missense were shown to impact regulation more than the hom truncation, while the truncated region was shown to previously to be important for ORMDL regulation.

Mice with a hom KO of the functional equivalent sptssb had early onset ataxia and died prematurely, with evidence of axonic degeneration.

Added comment: PMID 26854926: male 8 year old proband investigated for abdominal pain, fatigue, muscle weakness, and thyroid dysfunction (raised T4, normal T3, raised reverse T3) suggestive of impaired deiodinase activity in combination with low plasma selenium levels. Homozygosity mapping led to identification of a a single nucleotide change, C65G, in TRU-TCA1-1, a tRNA in the selenocysteine incorporation pathway. This mutation resulted in reduction in expression of stress-related selenoproteins. A methylribosylation defect at uridine 34 of mutant tRNA observed in patient cells was restored by cellular complementation with normal tRNA.

PMID 34956927: a 10 year old originally investigated for Hashimoto's disease was found to be homozygous for the same C65G variant identified in the previous paper, inherited from the father in what was concluded to be paternal isodisomy.

Added comment: PMID: 34009673- patients with constitutional mosaic aneuploidy were found to have biallelic mutations in CENATAC(CCDC84). 2 adult siblings with mosaic aneuploidies, microcephaly, dev delay, and maculopathy. Both chet for a missense and a splice site deletion- but the paper days these both result in the creation of a novel splice site that leads to frameshifts and loss of the c-terminal 64 amino acids.

Gene is shown to be part of a spliceosome. CENATAC depletion or expression of disease mutants resulted in retention of introns in ~100 genes enriched for nucleocytoplasmic transport and cell cycle regulation, and caused chromosome segregation errors.

Functional analysis in CENATAC-depleted HeLa cells demonstrated chromosome congression defects and subsequent mitotic arrest, which could be fully rescued by wildtype but not mutant CENATAC. Expression of the MVA-associated mutants exacerbated the phenotype, suggesting that the mutant proteins dominantly repress the function of any residual wildtype protein.

Review for gene: TRPC5 was set to AMBER
Added comment: PMID: 36323681; Leitão E. et al. (2022) Nat Commun.13(1):6570:
Missense variant NM_012471.2:c.523C>T, p.(Arg175Cys in three brothers with intellectual disability (ID) and autistic spectrum disorder (ASD), inherited from an asymptomatic mother and absent in the maternal grandparents.
Whole cell patch clamp studies of HEK293 created by site-directed mutagenesis showed increased current of this calcium channel (constitutively opened).
(This variant is absent in gnomAD v2.1.1).

Also, the nonsense variant, c.965G> A, p.(Trp322*) was found in a high functioning ASD male (maternally inherited), NMD-predicted.

Other papers and TRPC5 variants that were cited to associate this gene with X-linked ID and/or ASD include:
PMID: 24817631; Mignon-Ravix, C. et al. (2014) Am. J.Med. Genet. A 164A: 1991–1997: A hemizygous 47-kb deletion in Xq23 including exon 1 of the TRPC5 gene. He had macrocephaly, delayed psychomotor development, speech delay, behavioural problems, and autistic features. Maternally inherited, and a family history compatible with X-linked inheritance (i.e., maternal great uncle was also affected, although not tested).

In addition, PMID: 36323681; Leitão E. et al. (2022) cites papers with the variants p.(Pro667Thr), p.(Arg71Gln) and p.(Trp225*).
NB. p.(Pro667Thr) is absent in gnomAD (v2.1.1), p.(Arg71Gln) is also absent (the alternative variant p.(Arg71Trp) is present once as heterozygous only). p.(Trp225*) is absent, and it should be noted that PTCs / LoF variants are very rare (pLI = 1).

However, looking further into the three references, the evidence is not as clear or as accurate as was stated.

The missense variant c.1999C>A, p.(Pro667Thr), was stated as de novo, but was actually maternally inherited but was still considered a candidate for severe intellectual disability (shown in the Appendix, Patient 93, with severe speech delay, autism spectrum disorder and Gilles de la Tourette). This patient also has a de novo MTF1 variant. Reference: PMID: 23033978; de Ligt, J. et al. (2012) N. Engl. J. Med. 367: 1921–1929).

Missense variant (de novo): c.212G>A, p.(Arg71Gln), was found as part of the Deciphering Developmental Disorders (DDD) study and is shown in individual 164 in Supplementary Table 2 of PMID: 33504798; Martin, HC. et al. (2021) Nat. Commun.12: 627. Also displayed in DECIPHER (DDD research variant) with several phenotype traits, but ID and ASD are not specifically mentioned.

Nonsense variant: c.674G>A. p.(Trp225*) was stated as de novo but was inherited (reference PMID: 28191890; Kosmicki, JA. et al. (2017) Nat. Genet. 49: 504–510. Supplement Table 7). This was a study of severe intellectual delay, developmental delay / autism. (NB. The de novo p.(Arg71Gln) variant from the DDD study is also listed (subject DDD 342 in Supplement 4 / Table 2).

Mendeliome v1.601 BSN Krithika Murali changed review comment from: Ye et al 2022, Neurogenetics identified 4 unrelated individuals with epilepsy and compound heterozygous BSN variants via trio WES (combination of null and missense). Homozygous knockout mouse models showed abnormal CNS transmission and seizure activity. None of the identified variants were present in population databases as homozygotes. One individual had ID and microcephaly but all other individuals with biallelic variants had normal development.

In addition, heterozygous variants were identified in unrelated affected individuals - 2 apparently co-segregating missense variants and 2 de novo null variants. These variants were either absent in population databases or rare. The authors note that affected individuals with heterozygous variants had milder disease - either requiring no therapy or monotherapy only. Heterozygous knockout mice had no phenotype and there were not enough affected individuals in the families to truly determine co-segregation. In addition, carrier parents of individuals with biallelic variants did not appear to be affected.

Association between biallelic variants and epilepsy stronger than for monoallelic.

Added comment: Candidate disease gene for human calcium oxalate nephrolithiasis.

Performed exome sequencing and directed sequencing of the OXGR1 locus in a worldwide nephrolithiasis/nephrocalcinosis (NL/NC) cohort, and putatively deleterious rare OXGR1 variants were functionally characterised.

A heterozygous OXGR1 missense variant (c.371T>G; p.Leu124Arg) co-segregated with calcium oxalate NL and/or NC disease in an autosomal dominant inheritance pattern within a multi-generational family with five affected individuals.

Interrogation of the OXGR1 locus in 1,107 additional NL/NC families identified five additional deleterious dominant variants in five families with calcium oxalate NL/NC. Rare, potentially deleterious OXGR1 variants were enriched in NL/NC subjects relative to ExAC controls. Four missense variants and one frameshift variant.

Four of five NL/NC-associated missense variants revealed impaired AKG-dependent calcium ion uptake, demonstrating loss of function.

Rare, dominant loss-of-function OXGR1 variants are associated with recurrent calcium oxalate NL/NC disease. Six potentially deleterious variants were identified in six of 1,108 NL/NC families (0.54%).

Limitations: only probands were able to be recruited for four of six families. In the future, it will be important to determine whether any of the affected family members share the identified OXGR1 variant. They also observe OXGR1 variants in 0.16% of ExAC subjects (selected on the basis of the absence of paediatric disease).

Added comment: Cornière et al. 2022 (PMID: 35115415) identified a single family with a heterozygous missense VUS (c.1519C>T/p.R507W) in the SLC26A6 gene. However, the variant was found in 5 out of 280 674 alleles reported in gnomAD (Europeans and South Asians). In vitro studies showed that the variant affects both SLC26A6 transport activity and membrane surface expression, in turn reducing Cl− dependant oxalate transport. Cotransfection studies indicated a dominant-negative effect on WT. Slc26a6 null mice similarly displayed hyperoxalemia and hyperoxaluria which were caused by defective intestinal back-secretion of dietary oxalate (PMID: 21170874; 32660969)

SLC26A6 is currently not associated with any human phenotype in OMIM or G2P.

Physiological studies in myofibers isolated from patients’ biopsies revealed a markedly reduced force response of the sarcomeres to [Ca2+]. This pathomechanism was further confirmed in experiments in which contractile dysfunction was evoked by replacing TnC in myofibers from healthy control subjects with recombinant, mutant TnC. Conversely, the contractile dysfunction of myofibers from patients was repaired by replacing endogenous, mutant TnC with recombinant, wild-type TnC.

Borderline Green: sufficient segregation in Fam 1 plus de novo status in Fam 2, plus functional data.

Added comment: From PMID: 36333996.; Harrer, P. et al. (2022) Ann Neurol. doi: 10.1002/ana.26544.

Three patients from unrelated families with dystonia and/or Leigh(-like) syndromes, with biallelic variants in NUP54, in the C-terminal protein region that interacts with NUP62. Onset was between 12 months and 5 years. All had progressive neurological deterioration with dystonia, ataxia, dysarthria, dysphagia, hypotonia.

Patient / Family A (consanguineous) was homozygous for c.1073T>G p.(Ile358Ser).

Patient / Family B was compound heterozygous for c.1073T>G p.(Ile358Ser) and c.1126A>G p.(Lys376Glu).

Patient / Family C was compound heterozygosity for c.1410_1412del p.(Gln471del) and two missense variants c.1414G>A, p.(Glu472Lys); c.1420C>T, p.(Leu474Phe)

The phenotypes were similar to those of NUP62 including early-onset dystonia with dysphagic choreoathetosis, and T2-hyperintense lesions in striatum.

Brain MRIs showed T2/FLAIR hyperintensities in the dorsal putamina.

Publications for gene: GABRA3 were set to PMID: 29053855
Phenotypes for gene: GABRA3 were set to Epilepsy, intellectual disability, dysmorphic features,
Penetrance for gene: GABRA3 were set to Incomplete
Review for gene: GABRA3 was set to GREEN
Added comment: Six variants in GABRA3 encoding the alpha3-subunit of the GABA(A) receptor.
Five missense variants and one micro duplication were detected in four families and two sporadic cases presenting with a range of epileptic seizure types, a varying degree of intellectual disability and developmental delay, sometimes with dysmorphic features or nystagmus.
The variants co-segregated mostly but not completely with the phenotype in the families, indicating in some cases incomplete penetrance, involvement of other genes, or presence of phenocopies.
Overall, males were more severely affected and there were three asymptomatic female mutation carriers compared to only one male without a clinical phenotype.
Mechanism suggested - three detected missense variants are localised in the extracellular GABA-binding NH2-terminus, one in the M2-M3 linker and one in the M4 transmembrane segment of the alpha3-subunit. Functional studies in Xenopus leaves oocytes revealed a variable but significant reduction of GABA-evoked anion currents for all mutants compared to wild-type receptors. The degree of current reduction correlated partially with the phenotype.
Results reveal that rare loss-of-function variants in GABRA3 increase the risk for a varying combination of epilepsy, intellectual disability/developmental delay and dysmorphic features, presenting in some pedigrees with an X-linked inheritance pattern.

Added comment: PMID: 34750991:
- Two affected cousins, presented with recurrent episodes of severe lactic acidosis, hyperammonaemia, hypoglycaemia and encephalopathy.
- Both have a 2.2 kb homozygous deletion of exons 2 and 3 of UQCRH, predicted to culminate in an in-frame deletion exons 2 and 3 of the four-exon UQCRH gene, resulting in a shortened product.
- Mouse model with the equivalent homozygous Uqcrh deletion (Uqcrh-/-) also presented with lactic acidosis and hyperammonaemia, but had a more severe, non-episodic phenotype, resulting in failure to thrive and early death.
- Patient fibroblasts and Uqcrh-/- mouse tissues showed a CIII defect.
- Expression of wild-type UQCRH in patient fibroblasts ameliorates the CIII defect.

Added comment: PMID:36336956 describes a 9-year-old boy with severe DD, lack of speech, pyramidal signs, and limb ataxia who had a de novo missense variant Asp126His in FEM1C ascertained by WES. The equivalent variant introduced into the nematode C.elegans resulted in disabled locomotion caused by synaptic abnormalities and not muscle dysfunction.

An alternate change Asp126Val was reported in the DDD study de novo in a patient with uncharacterised developmental delay (PMID:28135719).

The Asp126 residue (but not either of the variants above specifically) was shown to be functionally important by in vitro studies (PMID:33398170;33398168). The residue is highly conserved and located in a region of missense constraint.

Borderline green, 2 patients and an animal model. Note all evidence points to the Asp126 residue being of specific importance.

A mouse model of the missense variant demonstrated a bioenergetic defect and a phenotype of mitochondrial diseases. It also strongly suggested that the variant is hypomorphic because mice homozygous for this variant showed a milder phenotype than those with a homozygous Tomm7 deletion.

Added comment: Biallelic PTPA pathogenic variants lead to a form of ID with later-onset parkinsonism based on 4 individuals from 2 families in the literature. Affected individuals were homozygous for missense variants demonstrated to result to reduced mRNA and protein levels as well as PP2A complex activation. Drosophila studies support an age-dependent locomotor dysfunction. Variants in other PP2A-complex-related genes also lead to NDDs. Summary provided below.

There is currently no associated phenotype in OMIM, G2P, PanelApp UK or SysID.

Consider inclusion in relevant panels (ID, Parkinsonism/movement disorders, etc) with amber rating pending further reports.

------

Fevga, Tesson et al (2022 - PMID: 36073231) describe the features of 4 individuals, from 2 unrelated families, with biallelic pathogenic PTPA variants.

These presented with normal or delayed early milestones, learning disability and ID (mild to moderate) followed by progressive signs of parkinsonism (at the age of 11 yrs in 2 sibs, 15 yrs in another individual). Motor symptoms were responsive to levodopa and later to deep brain stimulation.

Linkage analysis in one consanguineous family followed by exome revealed homozygosity for a missense PTPA variant (NM_178001:c.893T>G/p.Met298Arg). Exome sequencing in affected subjects from the 2nd family revealed homozygosity for a further missense variant (c.512C>A/p.Ala171Asp). There were no other candidate variants for the phenotype following parental / segregation studies.

Role of the gene:
As the authors discuss, PTPA (or PPP2R4) is ubiquitously expressed in all tissues incl. brain and encodes a phosphotyrosyl phosphatase activator of the dimeric form of protein phosphatase-2A (PP2A). PP2A in turn, is the major Ser/Thr phosphatase in brain targeting a large number of proteins involved in diverse functions. Activation of PP2A is dependent on its methylation, which is negatively regulated by the PP2A-specific methylesterase (PME-1). By binding to PME-1, PTPA counteracts the negative influence of the former on PP2A. Pathogenic variants in genes encoding subunits/regulators of the PP2A complex (e.g. PPP2R1A or PPP2CA) are associated with neurodevelopmental disorders.

Variant studies:
Upon overexpression of wt and both variants in a HEK-293 cell line the authors demonstrated that both variants resulted in significantly reduced mRNA and protein levels (which for Ala171Asp were attributed to increased proteasomal degradation). Both variants were shown to result in impaired PP2A complex activation compared to wt.

Drosophila / animal models:
Pan-neuronal RNAi-mediated knockdown of ptpa in Drosophila resulted in an age-dependent locomotor dysfunction, reversible with L-DOPA treatment.
Previous studies in mice suggest cognitive/electrophysiological impairments upon downregulation of PP2A activity in transgenic mice.

Mendeliome v1.323 NODAL Zornitza Stark edited their review of gene: NODAL: Added comment: NODAL is a good biological candidate for heterotaxy disorders, and this is supported by animal models. The gene is depleted for LoF variants in gnomad.

The missense variants reported in PMIDs 9354794 and 19064609 are present at a high population frequency in gnomad, including some in homozygous case: their association with disease is DISPUTED.

A total of at least 7 families reported with severe CHD and high impact variants (stop gain, frameshift and canonical splice site). However, almost invariably these were inherited from unaffected or questionably affected parents (e.g. self reports of heart murmur in childhood), raising questions about whether these variants contribute to disease under a monogenic or polygenic model and/or about penetrance.

All variants involved conserved amino acids in or close to the ATPase activity-related motifs in the catalytic motor domain of the KIF5B protein. No functional studies of variants. Previously 2 animal model experiments showed that loss of function of KIF5B can cause kyphomelic dysplasia. First, chondrocyte-specific knockout of Kif5b in mice was shown to produce a disorganized growth plate, leading to bone deformity. Second, double mutants disrupting the two zebrafish kif5b caused abnormal skeletal morphogenesis and the curvature of Meckel's and ceratohyal cartilages.

None of the three achieved verbal communication or ambulation (sitting / standing) at any age. They had mild dysmorphism of borderline dolichocephaly and microcephaly, prominent bushy eyebrows, flat midface, long nasal bridge and micrognathia. All three had micropenis with undescended testes. One of the affected (as a toddler) underwent thorough endocrinological analysis: testosterone and gonadotropin levels were low.

Added comment: 6 missense variants and 1 nonsense variant (NOT NMD-predicted, single-exon gene) reported in 7 males and 1 female with neurodevelopmental disorders. Phenotypes included dev delay, mild to severe ID, delayed or absent speech, seizures and brain MRI anomalies (in some patients).

The nonsense variant was identified in two affected brothers but not in the mother, suggesting it was de novo in the maternal germline. The variant in the one affected female was de novo. All other variants in hemizygous males were inherited from an unaffected mother. In one case, the variant was also identified in the unaffected grandmother.

Functional studies showed some but not all variants displayed impaired membrane transport and impaired excitatory synapse-promoting effects. Conditional knockout mice exhibited impaired long-term memory and abnormal gait.

One with Jewish / Tunisian ancestry: Onset was at 8 months, three episodes of febrile tonic-clonic 1 seizures of the four limbs, with eye rolling, loss of consciousness, transient left and right post-2 ictal hemiparesis and vomiting. The other with Asian / European ancestry: Onset was at 30 months with three iterative episodes of febrile and non-febrile hemiplegia and loss of 18 consciousness. The recurrent episodes alternatively involved the left-and 19 right-hand side, then generalised and were followed by post ictal hemiparesis.

CT scans of both showed brain calcifications and aberrant blood flow patterns. Transfected cell lines with this variant, c178G>A, showed higher chloride ion permeability and lower sodium ion permeability when compared to wildtype.

Summary: 4 families reported with non-obstructive azoospermia or premature ovarian insufficiency. Functional studies have been performed and mouse models recapitulate the phenotype.

PMID: 35674372 CNV and frameshift variants in KASH5 were identified in a non-obstructive azoospermia affected patient and in his infertile sister by whole-exome sequencing and CNV array. Kash5 knockout mouse displayed similar phenotypes, including a meiotic arrest at a zygotene-like stage and impaired pairing and synapsis.

PMID: 35708642 Hom splice identified in KASH5 in 2 sisters with premature ovarian insufficiency. In vitro studies found the variant disturbed the nuclear membrane localization of KASH5 and its binding with SUN1. Moreover, the Kash5 C-terminal deleted mice revealed defective meiotic homolog pairing and accelerated depletion of oocytes.

Homozygous Copg1K652E mice had increased ER stress in activated T and B cells, poor antibody responses, and normal numbers of T cells that proliferated normally, but underwent increased apoptosis upon activation. Exposure of the mutants to pet store mice caused weight loss, lymphopenia, and defective T cell proliferation that recapitulated the findings in the patients. The ER stress-relieving agent tauroursodeoxycholic acid corrected the immune defects of the mutants and reversed the phenotype they acquired following exposure to pet store mice.

Added comment: 2 unrelated patients with ID, microcephaly, short stature, dysmorphic features reported with biallelic variants:

P1 (3yo male): homozygous start-loss variant (2 hets and 0 hom in gnomAD). Functional testing showed a small amount of full-length protein was translated, and BUB1 recruitment to kinetochores was nearly undetectable.
P2 (16yo female): compound heterozygous for a canonical splice variant (1 het and no hom in gnomAD) and an NMD-predicted frameshift variant (absent from gnomAD). The splice variant was shown to result in an in-frame deletion of 54 amino acids in the kinase domain. P2 cells have reduced protein levels but essentially no kinase activity.

BUB1 patient cells have impaired mitotic fidelity.

Homozygous Bub1 disruption in mice is embryonic lethal (PMID:19772675). A hypomorphic mouse is viable with increased tumourigenesis with ageing and aneuploidy (PMID:19117986). A kinase-dead mouse does not show increased tumourigenesis but does have a high frequency of aneuploid cells (PMID:23209306)

- K/O mice show autophagy, redox regulation, and polyunsaturated fatty acid (PUFA)–containing lipids and die prematurely from microangiopathic glomerulosclerosis with immunodeficiency.
- 2 unrelated families (3 patients) w/ a homozygous missense (p.Gly153Val) and nonsense (p.Trp86*). All unaffected siblings were heterozygous.
Patient 1 (missense) presented with Coombs-positive hemolytic anemia, hepatosplenomegaly, Cranial MRI showed bilateral effusions, sulcal hyperintensity, and lateral parietal subcortical acute focal ischemic lesions.
Patient 2 (nonsense) presented with recurrent purulent otitis media and a chronic wet cough, persistent jaundice, recurrent chest and ear infections, lingular consolidation, mild bronchiectasis, bibasilar bronchial wall thickening, right peribronchial consolidation, right lower lobe bronchiectasis, bilateral axillary lymphadenopathy, and splenomegaly.
Patient 3 (nonsense) presented with suffered headaches, abdomen pain, mouth ulcers, and recurrent infections

- Functional studies show patient 1 (missense) with reduced protein expression on western blot, and patient 2/3 (nonsense) with no protein expression. T cells of Pt 1 were similar to mouse K/O model (elevated basal LC3-II, reduced autophagic flux).

gnomAD: 0 homozygous PTCs, but a very common canonical splice which is present in the non-canonical transcript

Added comment: GWAS data: Combined evidence from summary-based Mendelian randomization studies and profiling of human loss-of-function allele carriers showed an inverse relation between TRIM47 expression in the brain and blood vessels and extensive small vessel disease severity. Observed significant enrichment of Trim47 in isolated brain vessel preparations compared to total brain fraction in mice, in line with the literature showing Trim47 enrichment in brain endothelial cells at single cell level. Functional evaluation of TRIM47 by small interfering RNAs-mediated knockdown in human brain endothelial cells showed increased endothelial permeability, an important hallmark of cerebral small vessel disease pathology.

Added comment: 4 children from 3 related families with developmental delay, hypotonia, seizures, failure-to-thrive, strabismus, drooling, recurrent otitis media, hearing impairment, genitourinary malformations, and common facial features (arched eyebrows, prominent eyes, broad nasal bridge, low-hanging columella, open mouth, thick lower lip, protruding tongue, large low-set ears, and parietal bossing). WES revealed a homozygous frame-shift variant (p.Thr612Glnfs*22) in PROSER1. This encodes the proline and serine rich protein 1, part of the histone methyltransferases KMT2C/KMT2D complexes. PROSER1 stabilizes TET2, a member of the TET family of DNA demethylases which is involved in recruiting the enhancer-associated KMT2C/KMT2D complexes and mediating DNA demethylation, activating gene expression. Therefore, PROSER1 may play vital and potentially general roles in gene regulation. No functional assays and 3 related families, likely founder effect.

Mendeliome v1.3 RDH11 Zornitza Stark edited their review of gene: RDH11: Added comment: 2nd case reported: 1 Chinese patient with retinitis pigmentosa, juvenile cataracts, intellectual disability, and myopathy. Trio-based WES and whole genomic CNV detection found compound heterozygous variants in RDH11 (p.Leu313Pro and c.75-3C>A) with biparental inheritance. Variant c.75-3C>A was confirmed to be a splice-site mutation by cDNA sequencing. It caused exon 2 skipping, resulting in a frameshift mutation and premature translation termination (p.Lys26Serfs*38). They found mislocalization of RDH11 protein in muscle cells of the patient by using immunofluorescence staining. Retinol dehydrogenase 11 (RDH11) is an 11-cis-retinol dehydrogenase that has a well-characterized, albeit auxiliary role in the retinoid cycle. Diseases caused by mutations in the RDH11 gene are very rare, and only one affected family with eye and intelligence involvement has been reported.; Changed rating: AMBER; Changed publications: 24916380, 15634683, 30731079, 18326732, 34988992

Review for gene: ADD1 was set to GREEN
Added comment: 4 unrelated individuals affected by ID and/or complete or partial agenesis of corpus callosum, and enlarged lateral ventricles. WES found loss-of-function variants - 1 recessive missense variant and 3 de novo variants. The recessive variant is associated with ACC and enlarged lateral ventricles, and the de novo variants were associated with complete or partial agenesis of corpus callosum, mild ID and attention deficit. Human variants impair ADD1 protein expression and/or dimerization with ADD2. Add1 knockout mice recapitulate corpus callosum dysgenesis and ventriculomegaly phenotypes. Three adducin genes (ADD1, ADD2, and ADD3) encode cytoskeleton proteins that are critical for osmotic rigidity and cell shape. ADD1, ADD2, and ADD3 form heterodimers (ADD1/ADD2, ADD1/ADD3), which further form heterotetramers. Adducins interconnect spectrin and actin filaments to form polygonal scaffolds beneath the cell membranes and form ring-like structures in neuronal axons. Adducins regulate mouse neural development, but their function in the human brain is unknown

Mendeliome v0.14647 GJA5 Chirag Patel commented on gene: GJA5: Gollob et al. (2006) presented evidence that tissue-specific mutations in the GJA5 gene may predispose the atria to fibrillation. They identified a heterozygous missense mutation in blood and cardiac tissue in patient with AF. They also found 3 heterozygous missense mutations in cardiac tissue only in 3 other patients, indicating a somatic source of the genetic defects

Yang et al. (2010) identified a heterozygous nonsense mutationin a 64-year-old female patient who was diagnosed with paroxysmal AF at 32 years of age. The mutation was detected in 6 additional affected family members, but was not found in 6 unaffected family members or in 200 ethnically matched controls.

Yang et al. (2010) identified 3 heterozygous missense mutations in 3 probands with AF. The mutations segregated with disease in all 3 families and were not found in 200 ethnically matched controls.

Sun et al. (2013) identified a heterozygous missense mutation in a 42-year-old woman who had been diagnosed with AF at age 40 years. The mutation was also detected in her father, who had been diagnosed with lone AF at 41 years of age, but it was not found in unaffected family members, in 200 controls, or in the dbSNP database. Functional analysis demonstrated that the I75F mutant is unable to form functional gap junction channels and also impairs coupling when expressed with wildtype CX40 or CX43.

Added comment: p.(Arg192Ter), a truncating variant that results in loss of 6 amino acids, was detected in two families (one Polish and one Korean) with hearing loss. Four affected (heterozygous) and two unaffected (neg) were tested, however 14 members had been diagnosed with HL in a large multi generational family (gene panel 237 genes). The second family (WES) had two affected heterozygous and no unaffected were tested. This same variant had previously been reported in a Danish family (12 affected heterozygous and 13 unaffected negative, but one younger member unaffected are heterozygous) with hearing loss (PMID: 26197441), for which functional studies in HEK cells demonstrated that the truncated protein was almost completely retained on the plasma cell membrane in contrast to the wild-type protein, which targeted primarily to the endo-lysosomal compartments. The YHTL motif, deleted by the c.574C>T nonsense mutation, is a canonical sorting motif
known to be recognized by specific adaptor proteins in the cytosol, leading to subcellular trafficking of the transmembrane protein to endosomes and lysosomes.

Added comment: 2 individuals with profound intellectual disability, epilepsy, white matter atrophy, microcephaly, and dysmorphic features, who carry damaging de novo heterozygous variants in DROSHA. Both variants are missense, absent from gnomad. Both individuals noted to have Rett-like features.

Functional studies in patient fibroblasts showed one of the missense altered the expression of mature miRNA.

PMID 29486293 Manley et al 2018 - proband is a 50 yo M with multiple ileal intusussceptions and IFPs and GIST. Heterozygous D846V germline variant identified. Variant identified in daughter and 2 siblings. Coarser face, coarser skin, broader hands and feet, unexplained premature loss of teeth requiring dentures in their 40s described in relatives with the variant, no polyps or tumour identified in screened family members. Pdgfra +/K mutant mice recapitulated the human phenotype. Mice with the constitutively activated mutant PDGFRA shown to have diffuse expansion of the gastrointestinal submucosa, which exhibits an increased number of spindled fibroblast-like cells and marked collagen deposition. Mutant mice also develop intestinal polyps morphologically similar to IFPs. The Pdgfra +/K mice also exhibit thickened skin due to excess collagen deposition within the dermis and subcutaneous tissues.

Added comment: No OMIM gene disease association reported

PMID 34934811 Nishimori et al report 2 individuals from a Japanese family with joint contractures, elevated CK and a novel heterozygous TNNI1 variant.

The proband was born with clasped thumbs (gestational age not stated) requiring surgical correction at 5 months of age. At age 14 was diagnosed with contractures of the neck, trunk, hip and knee with elevated serum CK (1689 IU/L). No muscle weakness noted. Muscle biopsy showed moth-eaten appearance of type I fibres and electron microscopy showed type 1 fibre Z disk streaming.

Trio exome sequencing identified a paternally heterozygous nonsense TNNI1 variant (c.523A>T p.K175*). The proband's father and paternal grandfather (not genotyped) also have a history of joint contractures with elevated CK.

The affected amino acid residue is in the tropomyosin binding site near the C-terminus and is highly conserved. The variant is absent from gnomAD. rt-PCR products of mRNA from the patient's muscle biopsy showed presence of both mutated and normal transcripts.

Added comment: Two apparently unrelated cases with spondyloepiphyseal dysplasia from India were identified with the same variant (c.84+3A>T). The kindred coefficient comparison of the 2 cases exome data suggested they were unrelated, however there was a stretch of shared homozygosity suggesting remote consanguinity. ~80% aberrantly spliced BNIP1 pre-mRNAs, reduced BNIP1 mRNA level to ~80%, and BNIP1 protein level reduction by ~50% were detected in one of the cases fibroblasts. A block at the terminal stage of autolysosome formation and/or clearance in patient fibroblasts was suggested based on the data. A drosophila model of the BNIP1 orthologue Sec20 also demonstrated defective autolysosome formation.

Mice with targeted T cell and B cell caspase-8 deficiency present normal thymocyte development but a marked decrease in peripheral blood T-cells. Besides, when challenged with the lymphocytic choriomeningitis virus (LCMV), these animals showed a significantly impaired immune response to the infection that included impaired CD8 cell expansion and an abrogated ability to generate virus-specific CD8+ cytotoxic T-cells.; to: Borderline red/amber

PMID: 32949790 - report two siblings with facial dysmorphism and lactic acidosis diagnosed neonatally with subsequent fatal early encephalopathy with apneic episodes, irritability, central hypoventilation, liver involvement and hyperammonemia. Cerebral white matter anomalies reported in one patient and cardiomyopathy in the other. WES identified homozygous nonsense NDUFAF4 variants with absent NDUFAF4 expression in patient fibroblasts. OXPHOS assembly studies demonstrated almost undetectable levels of fully assembled complex I and complex I–containing supercomplexes and an abnormal accumulation of SCIII2IV1 supercomplexes. Morphologically, fibroblasts showed rounder mitochondria and a diminished degree of branching of the mitochondrial network.

PMID: 28853723 - report one patient born at 38 weeks after IOL for IUGR. Presented age 7 months with developmental regression, growth failure and central hypotonia. Brain MRI revealed diffuse bilateral signal alterations in the basal ganglia and thalami and an EEG showed generalized slowing with multifocal spikes consistent with an epileptogenic focus. Homozygous missense NDUFAF4 variants identified. Lentiviral complementation of patient fibroblasts with wild-type NDUFAF4 rescued complex I deficiency and assembly defect

PMID 18179882 - report multiple affected individuals from one family. Most presented soon after birth with severe metabolic acidosis and high plasma lactate levels. Patients who survived longer were repeatedly admitted because of exacerbation of the acidosis during intercurrent infections.

Added comment: Klöckner (2022 - PMID: 35202461) describe the phenotype of 6 individuals (from 5 unrelated families) harboring biallelic CHKA variants.

Shared features incl. abnormal muscle tone(6/6 - hypertonia or hypotonia, 3/6 each), DD/ID (6/6,severe in 4, severe/profound in 2), epilepsy (6/6 - onset: infancy - 3y2m | epileptic spasms or GS at onset), microcephaly (6/6), movement disorders (3/6 - incl. dyskinesia, rigidity, choreoatetotic movements). 2/5 individuals exhibited MRI abnormalities, notably hypomyelination. Short stature was observed in 4/6.

Eventual previous genetic testing was not discussed.

Exome sequencing (quattro ES for 2 sibs, trio ES for 1 individual, singleton for 3 probands) revealed biallelic CHKA variants in all affected individuals. Sanger sequencing was performed for confirmation and segregation studies.

Other variants (in suppl.) were not deemed to be causative for the neurodevelopmental phenotype.

3 different missense, 1 start-loss and 1 truncating variant were identified, namely (NM_0012772.2):
- c.421C>T/p.(Arg141Trp) [3 hmz subjects from 2 consanguineous families],
- c.580C>T/p.Pro194Ser [1 hmz individual born to consanguineous parents],
- c.2T>C/p.(Met1?) [1 hmz individual born to related parents],
- c.14dup/p.(Cys6Leufs*19) in trans with c.1021T>C/p.(Phe341Leu) in 1 individual.

CHKA encodes choline kinase alpha, an enzyme catalyzing the first step of phospholipid synthesis in the Kennedy pathway. The pathway is involved in de novo synthesis of glycerophospholipids, phosphatidylcholine and phosphatidylethanolamine being the most abundant in eukaryotic membranes.

CHKA with its paralog (CHKB) phosphorylates either choline or ethanolamine to phosphocholine or phosphoethanolamine respectively with conversion of ATP to ADP.

As the authors comment, biallelic pathogenic variants in CHKB cause a NDD with muscular dystrophy, hypotonia, ID, microcephaly and structural mitochondrial anomalies (MIM 602541). [Prominent mitochondrial patterning was observed in a single muscle biopsy available from an individual with biallelic CHKA variants].

Other disorders of the Kennedy pathway (due to biallelic PCYT2, SELENOI, PCYT1A variants) present with overlapping features incl. variable DD/ID (no-severe), microcephaly, seizures, visual impairment etc.

CHKA variants were either absent or observed once in gnomAD, affected highly conserved AAs with multiple in silico predictions in favor of a deleterious effect.

In silico modeling suggests structural effects for several of the missense variants (Arg141Trp, Pro194Ser presumably affect ADP binding, Phe341 lying close to the binding site of phosphocholine).

Each of the missense variants was expressed in yeast cells and W. Blot suggested expression at the expected molecular weight at comparative levels. The 3 aforementioned variants exhibited reduced catalytic activity (20%, 15%, 50% respectively).

NMD is thought to underly the deleterious effect of the frameshift one (not studied).

The start-loss variant is expected to result in significantly impaired expression and protein function as eventual utilization of the next possible start codon - occurring at position 123 - would remove 26% of the protein.

Chka(-/-) is embryonically lethal in mice, suggesting that complete loss is not compatible with life. Reduction of choline kinase activity by 30% in heterozygous mice did not appear to result in behavioral abnormalities although this was not studied in detail (PMID cited: 18029352). Finally, screening of 1566 mouse lines identified 198 genes whose disruption yields neuroanatomical phenotypes, Chka(+/-) mice being among these (PMID cited: 31371714).

There is no associated phenotype in OMIM, Gene2Phenotype or SysID.

Overall this gene can be considered for inclusion in the ID and epilepsy panes with green or amber rating (>3 individuals, >3 variants, variant studies, overlapping phenotype of disorders belonging to the same pathway, etc). Consider also inclusion in the microcephaly panel (where available this seemed to be of postnatal onset).

Added comment: PMID: 33824347- Previously unknown type of sclerosing bone disorder in 4 independent families, bi-allelic LOF variants in TMEM53. 5 individuals from 4 families, all have proportional or short limbed stature, not identifiable at birth. Head deformities (macrocephaly, dolichocephaly, prominent forehead), epicanthic folds, thick vermilion of upper and lower lips. Vision diminished after early childhood due to optic nerve compression.

3 of 4 families confirmed consanguineous, and all affected members from all 4 families have homozygous variants inherited from heterozygous parents. 3 families have the same splicing variant proven to cause exon 2 skipping and an NMD frameshift by RT-PCR. The other family has a an NMD frameshift variant. So 4 families but only 2 variants.

Phenotypes for gene: CHP1 were set to Spastic ataxia 9, autosomal recessive, MIM #618438
Review for gene: CHP1 was set to GREEN
Added comment: 2 different consanguineous families with 2 affected siblings with ataxia (1 paediatric onset, 1 adult onset). 3 of the patients had cerebellar atrophy. WES identified homozygous variants in CHP1 gene in both families (K19del and Arg91Cys), which segregated with the disorder in the family.

Decreased CHP1 protein on IHC of cerebellar tissue in family with Arg91Cys variant. In vitro functional expression studies in HEK293 cells showed that the K19del mutation resulted in decreased protein expression, with normal levels of transcript, suggesting defects in protein stability. The mutant protein formed massive protein aggregates in transfected neuronal cell bodies and neurite-like projections, whereas the wildtype protein showed a more uniform distribution. The mutant protein altered CHP1 association into functional complexes and impaired membrane localization of the Na+/H+ transporter NHE1. The findings indicated that the CHP1 mutation likely causes ataxia in an NHE1-dependent manner, resembling the mechanism observed in the Chp1 vacillator mutant mouse.

Added comment: The primordial follicle pool is determined by the meiosis process, which is initiated by programmed DNA double strand breaks (DSB) and homologous recombination. PRDM9 is a meiosis-specific histone H3 methyltransferase and a major determinant of meiotic recombination hotspots in mammals. 3 pathogenic heterozygous variants in PRDM9 identified in 4 patients with POI. Functional studies showed the variants in PRDM9 impaired its methyltransferase activity. Prdm9+/- mice were subfertile, and showed increased percentage of germ cells at abnormal pachytene stage with decreased number of PRDM9-dependent DSBs and insufficient recombination.

Mendeliome v0.10181 ADCY5 Zornitza Stark edited their review of gene: ADCY5: Added comment: Neurodevelopmental disorder with hyperkinetic movements and dyskinesia (NEDHYD) is an autosomal recessive complex neurologic disorder characterized by severe global developmental delay with axial hypotonia, impaired intellectual development, poor overall growth, and abnormal involuntary hyperkinetic movements, including dystonia, myoclonus, spasticity, and orofacial dyskinesia. It is the most severe manifestation of ADCY5-related dyskinetic disorders. Five individuals from 2 families reported.

Autosomal recessive hyperkinetic movement disorder with dyskinesia, myoclonus, chorea, and dystonia-2 (HYDMCD2) is characterized by the onset of abnormal involuntary movements, mainly affecting the limbs and causing walking difficulties, in the first decade. The severity is variable; some patients have orofacial dyskinesia, resulting in speech difficulties, or develop neuropsychiatric features, including anxiety and social withdrawal. Cardiomyopathy has rarely been described and may be a manifestation of the disorder.

Mendeliome v0.10044 ECM1 Zornitza Stark changed review comment from: PMID: 11929856 - Hamada et al 2002 - looked at 6 different unrelated consanguineous families (from Saudi Arabia, Kuwait, Pakistan, The Netherlands, UK, and a group of South African families with a probable common ancestor) with a clinical diagnosis of Lipoid proteinosis (LP)/Urbach–Wiethe disease. They performed a genome-wide linkage analysis and identified a region and then looked at the expression of candidate genes in fibroblasts from patients compared to controls. ECM1 was found to have lower expression levels. 6 homozygous deletion variants were identified in the patients. In one family they established that the parents were heterozygous for the variant.

PMID: 28720532 - Afifi et al 2017 - studied 12 patients from 10 unrelated consanguineous Egyptian families with a clinical diagnosis of lipoid proteinosis. The patients reported progressive hoarseness of voice and easily damaged skin by minor trauma or friction. Homozygous ECM1 variants were detected in affected members in all families: 1 family had a missense variant, 5 families had splice site variants and 4 families had indels predicted to cause frameshifts. Parents were found to be heterozygous for the variants.

Classic features include beaded eyelid papules and laryngeal infiltration leading to hoarseness. The disorder is clinically heterogeneous, with affected individuals displaying differing degrees of skin scarring and infiltration, variable signs of hoarseness and respiratory distress, and in some cases neurologic abnormalities such as temporal lobe epilepsy. Histologically, there is widespread deposition of hyaline (glycoprotein) material and disruption/reduplication of basement membrane

Mendeliome v0.10041 SMPX Zornitza Stark edited their review of gene: SMPX: Added comment: PMID 33974137: Four different missense variants were identified in ten patients from nine families in five different countries. Haplotype analysis of patients with similar ancestry revealed two different founder mutations in Southern Europe and France, indicating that the prevalence in these populations may be higher. Clinical features: adult-onset, usually distal more than proximal limb muscle weakness, slowly progressing over decades with preserved walking. Lower limb muscle imaging showed a characteristic pattern of muscle involvement and fatty degeneration. Histopathological and electron microscopic analysis of patient muscle biopsies revealed myopathic findings with rimmed vacuoles and the presence of sarcoplasmic inclusions, some with amyloid-like characteristics. In silico predictions and subsequent cell culture studies showed that the missense mutations increase aggregation propensity of the SMPX protein. In cell culture studies, overexpressed SMPX localized to stress granules and slowed down their clearance.; Changed publications: 21549342, 21549336, 21893181, 22911656, 28542515, 33974137; Changed phenotypes: Deafness, X-linked 4, MIM# 300066, Distal myopathy, adult-onset

Somatic deletions of 20q are associated with chronic myeloid malignancies. Aziz et al showed that a single heterozygous 20q deletion consistently resulted in the complete loss of expression of the imprinted genes L3MBTL1 and SGK2, indicative of a pathogenetic role for loss of the active paternally inherited locus. Concomitant loss of both L3MBTL1 and SGK2 dysregulated erythropoiesis and megakaryopoiesis.

Review for gene: KCNQ1OT1 was set to AMBER
Added comment: Limited evidence that isolated intragenic variation in KCNQ1OT1 is definitively associated with a phenotype.

KCNQ1OT1 encodes the regulatory antisense non-coding RNA KCNQ1OT1 (KCNQ1 overlapping) and is located within the KCNQ1OT1:TSS DMR (imprinting control region 2; IC2) at 11p15.5. IC2 is located within KCNQ1 intron 10. KCNQ1OT1 is maternally imprinted and paternally expressed. On the paternal chromosome, KCNQ1OT1 is transcribed and represses in cis the flanking imprinted genes, including the growth inhibitor CDKN1C, which is normally transcribed from the maternal allele. In 50% of the BWS patients, loss of methylation (LOM) of IC2 leads to biallelic expression of KCNQ1OT1 and biallelic silencing of CDKN1C (PMID 30635621). Expression is increased in BWS due to IC2 epimutations or paternal UPD.

Single nucleotide variants within KCNQ1OT1 have not been definitively associated with human disease. A heterozygous maternally inherited non-coding variant was identified in an individual with isolated omphalocele. This variant was shown to alter the methylation pattern of the imprinted allele (PMID 29047350).

Eggerman et al (PMID 32447323) described a 132 base pair deletion within KCNQ1OT1 associated with growth retardation in the case of paternal but not maternal transmission. This intragenic deletion did not affect IC2 methylation.

Microdeletions of IC2 involving KCNQ1OT1 on the paternal allele have been identified in a small number of patients with Russell-Silver syndrome. Similarly, microdeletions of IC2 involving KCNQ1OT1 on the maternal allele have been identified in a small number of patients with BWS. These deletions also variably involve KCNQ1 or CDKN1C. LoF in CDKN1C is a known cause of BWS. There is some evidence to suggest that disruption of KCNQ1 prevents maternal methylation at IC2 (PMID 30778172).

Added comment: Single report of biallelic variants in this gene in a mother of a child with Multi locus imprinting disturbance (MLID) and a transient neonatal diabetes mellitus phenotype.

This gene encodes part of the subcortical maternal complex (SCMC). Other genes in this group act as 'maternal effect' genes and are associated with early embryonic arrest, recurrent hydatiform mole and MLID in offspring.

As is the case for other genes encoding components of the SCMC, the pathogenicity of variants can be difficult to establish as reproductive outcomes are not recorded in genomic databases and variants may be listed in population databases as they are not classed as pathogenic in males or women with no reproductive history.

Functional studies of genes encoding components of the SCMC are limited as their expression is restricted to the oocyte and early embryo.

Added comment: Moderate evidence for autosomal dominant short QT syndrome 1 by ClinGen /gene curation expert panel (PMID: 34557911). A single missense variant (absent gnomAD) identified in two SQTS families. In family 1, it segregated with SQTS (QTc<370ms) in 23 carriers, and 19 non-carriers had a QTc>370ms. In family 2, it segregated in 4 individuals. Experimental evidence from in vitro and zebrafish models suggests reduced membrane localization of the mutated protein leads to intracellular alkalinization and shortening of the cardiomyocyte action potential duration.

Added comment: Dworschak et al. (2021) via WES reported 10 patients from 7 families with biallelic (n=7) or de novo (n=3) PLXNA1 variants. Shared phenotypic features include global developmental delay (9/10), brain anomalies (6/10), and eye anomalies (7/10). Seizures were predominantly reported in patients with monoallelic variants. Zebrafish studies showed an embryonic role of plxna1a in the development of the central nervous system and the eye. Biallelic variants in the extracellular Plexin-A1 domains lead to impaired dimerization or lack of receptor molecules, whereas monoallelic variants in the intracellular Plexin-A1 domains might impair downstream signaling through a dominant-negative effect.

Mendeliome v0.9274 CDH15 Zornitza Stark commented on gene: CDH15: PMID: 19012874 - 4 unrelated patients with missense variants and mild-severe ID. Only two genes checked. All variants are common in gnomAD (>20 hets each) and classified as VUS or likely benign in ClinVar (paper is from 2008, pre-dates gnomAD). Functional studies were performed showing a LOF effect, where cell adhesion was reduced.
However NMD PTCs are present in gnomAD (many >=6 hets each)

PMID: 12052883 - null mouse model were viable, showed no gross developmental defects. In particular, the skeletal musculature appeared essentially normal. In the cerebellum of M-cadherin-lacking mutants, typical contactus adherens junctions were present and similar in size and numbers to the equivalent junctions in wild-type animals. However, the adhesion plaques in the cerebellum of these mutants appeared to contain elevated levels of N-cadherin compared to wild-type animals.

PMID: 28422132 - reviewed microdeletions spanning multiple genes including CDH15, suggests it may contribute to a more severe neurological phenotype, with particular regard to brain malformations.

Review for gene: ERGIC1 was set to AMBER
Added comment: Reinstein et al. (2018) used WES in a large consanguineous Israeli Arab kindred consisting of 16 patients affected with the neurogenic type of arthrogryposis multiplex congenita. They identified a homozygous missense (V98E) mutation in ERGIC1 gene, which segregated with the disorder in the kindred, and was not found in the ExAC database or in 212 ethnically matched controls. Functional studies of the variant and studies of patient cells were not performed. ERGIC1 encodes a cycling membrane protein which has a possible role in transport between endoplasmic reticulum and Golgi.

Marconi et al (2021) used genome sequencing in a consanguineous family with 2 affected siblings presenting congenital arthrogryposis and some facial dysmorphism. They identified a homozygous 22.6 Kb deletion encompassing the promoter and first exon of ERGIC1. mRNA quantification showed the complete absence of ERGIC1 expression in the two affected siblings and a decrease in heterozygous parents.

Added comment: No individuals reported with GPX1 variants identified as the cause of Haemolytic anaemia due to glutathione peroxidase deficiency. Multiple papers report a number of cases of Haemolytic anaemia due to glutathione peroxidase deficiency, however there is no defined link or variant to GPX1 (PMID: 5766310. PMID: 1131421, PMID: 2492138, PMID: 476008)

Overall, lowered glutathione peroxidase activity has been observed in a number of individuals with haemolytic anaemia however the evidence for a cause-and-effect relationship between the enzyme deficiency and the presenting anaemia is not evident.

Mendeliome v0.9088 IFIH1 Sarah Pantaleo changed review comment from: Rare, likely loss-of-functions IFIH1 variants identified in eight independent probands with Very Early Onset Inflammatory Bowel Disease (VEOIBD) from a combined cohort of 42 children. IFIH1 variants were significantly enriched in children with VEOIBD as compared to controls (p=0.007).
In one case of neonatal-onset IBD, a homozygous truncating variant was identified. seven carriers of LoF variants (three of whom have a second hypomorphic missense variant). Luciferase reporter assays employed to assess MDA5 activity (encoded by IFIH1). In three cases, the functional studies demonstrated that the second missense variant either did not affect protein function or was in cis with the LoF variant.; to: IFIH1 encodes MDA5, a key cystolic sensor for viral nucleic acids. Rare, likely loss-of-functions IFIH1 variants identified in eight independent probands with Very Early Onset Inflammatory Bowel Disease (VEOIBD) from a combined cohort of 42 children. IFIH1 variants were significantly enriched in children with VEOIBD as compared to controls (p=0.007).
In one case of neonatal-onset IBD, a homozygous truncating variant was identified. There were seven carriers of LoF variants identified (range of onset 6 months to 6 years of age). In three of these cases, a second hypomorphic missense variant was identified.
Luciferase reporter assays were employed to assess MDA5 activity. In some cases, the second missense variant was either proven to not affect protein function or was in cis with the LoF variant.
Complete and partial MDA5 deficiency is associated with VEOIBD with variable penetrance and expressivity, suggesting a role for impaired intestinal viral sensing in IBD pathogenesis.

Expanded repeat in NOTCH2NLC sequence is (GGC)9(GGA)2(GGC)2.
Large number of families and sporadic cases reported with expansions, with a range of neurodegenerative phenotypes, including: dementia, Parkinsonism/tremor, peripheral neuropathy, leukoencephalopathy, myopathy, motor neurone disease.
Normal repeat range: 4-40, 1 control had 61 repeats and may have been a presymptomatic carrier.
Intermediate range: 41-60 identified in Parkinson's disease
Pathogenic repeat range: >=60-520
Mechanism of disease is translation of repeat expansion into a toxic polyglycine protein, identified in both mouse models and tissue samples from affected individuals.

Mendeliome v0.8861 IGF2 Zornitza Stark changed review comment from: RSS phenotype.; to: Silver-Russell syndrome-3 (SRS3) is characterized by intrauterine growth retardation with relative macrocephaly, followed by feeding difficulties and postnatal growth restriction. Dysmorphic facial features include triangular face, prominent forehead, and low-set ears. Other variable features include limb defects, genitourinary and cardiovascular anomalies, hearing impairment, and developmental delay. Disruption of any gene in the HMGA2-PLAG1-IGF2 pathway results in a decrease in IGF2 expression and produces an SRS phenotype similar to that of patients carrying 11p15.5 epigenetic defects.

Begemann et al. (2015) performed exome sequencing in 4 affected people with severe growth restriction in one family, and identified a heterozygous nonsense mutation in the IGF2 gene that segregated fully with the disorder. Affected individuals inherited the mutation from their healthy fathers, and it originated from the healthy paternal grandmother. Clinical features occurred only in those who inherited the variant allele through paternal transmission, consistent with maternal imprinting of IGF2.

Many other cases reported since with de novo mutations in IGF2 present on the paternal allele.

Review for gene: RNF220 was set to GREEN
Added comment: Sferra et al (2021 - PMID: 33964137) provide extensive evidence that biallelic RNF220 mutations cause a disorder characterized by hypomyelinating leukodystrophy, ataxia (9/9 - onset 1-5y), borderline intellectual functioning (3/9) / intellectual disability (5/9 - in most cases mild), sensorineural deafness (9/9) with complete hearing loss in the first decade of life, hepatopathy (9/9) with associated periportal fibrosis, and dilated cardiomyopathy (9/9) which was fatal.

Other neurologic manifestations apart from ataxia incl. hyperreflexia (8/8), spastic paraplegia (9/9), dysarthria (9/9), peripheral neuropathy (4/9), seizures in one case (1/9). Upon brain MRI there was thin corpus callosum (9/9) or cerebellar atrophy in some (2/9).

The authors identified homozygosity for 2 recurrent missense RNF220 variants in affected members belonging to these 5 broad consanguineous pedigrees (7 families), namely NM_018150.4:c.1094G>A / p.Arg365Gly in 4 Roma families in the context of a shared haplotype (/founder effect) as well as c.1088G>A / p.Arg363Gly in a large pedigree from southern Italy initially reported by Leuzzi et al (2000 - PMID: 10881263).

Extensive segregation analyses were carried out including several affected and unaffected members.

RNF220 encodes ring finger protein 220, which functions as an E3 ubiquitin ligase. Previous studies have shown among others a role in modulation of Sonic hedgehog/GLI signaling and cerebellar development

Evidence for the role of RNF220 included relevant expression, localization within the cell, interaction partners (lamin B1, 20S proteasome), similarities with other laminopathies in terms of phenotype, etc :
*RNF220 has a relevant expression pattern in CNS (based on qRT-PCR analyses in human brain, cerebellum, cerebral cortex / mRNA levels in human fetal CNS with higher expression in cerebellum, spinal cord and cortex / previous GTEx data / protein levels in mouse CNS)
*The protein displays nuclear localization based on iPSC cells differentiated to motor neurons (also supported by data from the Human Protein Atlas). Transfection of COS-1 cells demonstrated localization primarily to the nucleus (as also previously demonstrated in HEK293T cells) in vesicle like structures with ASF2/SF2 colocalization suggesting enrichment in nuclear speckles. There was also partial co-distribution with the 20S proteasome. R363Q and R365Q additionally coalesced in the cytoplasm forming protein aggregates/inclusions.
*Immunofluorescence studies in patient fibroblasts also confirmed abnormal increase of the protein in the cytoplasm and increased fluorescence with the 20S proteasome.
*Proteomic identification of RNF220-interacting proteins in transfected HEK293T cells demonstrated enrichment for all members of the lamin protein family (incl . lamin B1, AC, B2).
*RNAi-mediated downregulation of RNF222 in Drosophila suggested altered subcellular localization and accumulation of the fly orthologue for human lamin B1.
*Immunoprecipitation of lamin B1 from the nuclear matrix of cerebellar cells suggested significant interaction of endogenous lamin B1 with RNF220, while transfection studies in HEK293T cells for wt/mt suggested reduced binding to endogenous lamin B1 for RNF220 mt compared to wt (more prominent for R365Q). RNF220 mutants also reduced ubiquitination of nuclear lamin B1 compared to wt.
*Patient fibroblasts immunostained with different nuclear envelope markers displayed abnormal nuclear shapes with multiple invaginations and lobulations, findings also observed in laminopathies.

Added comment: Sakamoto et al (2021 - PMID: 34346499) provide some evidence that monoallelic ARF3 pathogenic variants may be associated with a NDD with brain abnormality.

Using trio exome sequencing, the authors identified 2 individuals with NDD harboring de novo ARF3 variants, namely: NM_001659.2:c.200A>T / p.Asp67Val and c.296G>T / p.Arg99Leu.

Individual 1 (with Asp67Val / age : 4y10m), appeared to be more severelely affected with prenatal onset progressive microcephaly, severe global DD, epilepsy. Upon MRI there was cerebellar and brainstem atrophy. Individual 2 (Arg99Leu / 14y) had severe DD and ID (IQ of 23), epilepsy and upon MRI cerebellar hypoplasia. This subject did not exhibit microcephaly. Common facial features incl. broad nose, full cheeks, small philtrum, strabismus, thin upper lips and abnormal jaw. There was no evidence of systemic involvement in both.

ARF3 encodes ADP-ribosylation factor 3. Adenosine diphosphate ribosylation factors (ARFs) are key proteins for regulation of cargo sorting at the Golgi network, with ARF3 mainly working at the trans-Golgi network. ARFs belong to the small GTP-binding protein (G protein) superfamily. ARF3 switches between an active GTP-bound form and an inactive GDP-bound form, regulated by guanine nucleotide exchange factors (GEFs) and GTPase activating proteins (GAPs) respectively.

Members of the ARF superfamily regulate various aspects of membrane traffic, among others in neurons.

There are 5 homologs of ARF families, divided in 3 classes. ARF3 and ARF1 belong to class I. Monoallelic ARF1 mutations are associated with Periventricular nodular heterotopia 8 (MIM 618185).

In vivo, in vitro and in silico studies for the 2 variants suggest that both impair the Golgi transport system although each variant most likely exerts a different effect (gain-of-function for Arg99Leu vs loss-of-function/dominant-negative for Asp67Val).

This was also reflected in somewhat different phenotype of the subjects with the respective variants. Common features included severe DD, epilepsy and brain abnormalities although Asp67Val was associated with diffuse brain atrophy as well as congenital microcephaly and Arg99Leu with cerebellar hypoplasia.

Evidence to support the effect of each variant include:

Arg99Leu:
Had identical Golgi localization to that of wt
Had increased binding activity with GGA1, a protein recruited by the GTP-bound active form of ARF3 to the TGN membrane (supporting GoF)
In silico structural analysis suggested it may fail to stabilize the conformation of Asp26, resulting in impaired GTP hydrolysis (GoF).
In transgenic fruit flies, evaluation of the ARF3 variant toxicity using the rough eye phenotype this variant was associated with increased severity of the r-e phenotype similar to a previously studied GoF variant (Gln71Leu)

Asp67Val:
Did not show a Golgi-like pattern of localization (similar to Thr31Asn a previously studied dominant-negative variant)
Displayed decreased protein stability
In silico structural analysis suggested that Asp67Val may lead to compromised binding of GTP or GDP (suggestive of LoF)
In transgenic Drosophila eye-specific expression of Asp67Val (similar to Thr31Asn, a known dominant-negative variant) was lethal possibly due to high toxicity in very small amounts in tissues outside the eye.

There is no associated phenotype in OMIM, G2P or SysID.

Added comment: Altuame et al (2021 - PMID: 34327814) describe 3 individuals from 2 consanguineous Arab families with biallelic PLXNA2 variants.

The index patient from the 1st family presented with CHD (hypoplastic right ventricle, ASD), DD and moderate ID (IQ of 40), failure to thrive as well as some dysmorphic features (obtuse mandibular angle, mild overbite, synophrys with downslanting p-f, strabismus, etc). There were additional features (eg. postaxial polydactyly) which were found in other affected and unaffected family members.

Exome sequencing with autozygome analysis revealed homozygosity for a PLXNA2 stopgain variant (NM_025179:c.3603C>A / p.(Cys1201*)).

Sanger confirmation was carried out and segregation analyses confirmed carrier status of the unaffected parents and a sib as well as a brother homozygous for the same variant. Clinical evaluation of the latter, following this finding revealed borderline intellectual functioning, ADHD, failure to thrive. There was no mandibular anomaly or overbite and no clinical evidence of CHD (no echo performed).

The index patient from the 2nd consanguineous family was evaluated for ID (IQ of 63), with previous borderline motor development, ADHD and some dysmorphic features (obtuse mandibular angle and overbite). There was no clinical evidence of CHD (no echo performed).

Exome sequencing with autozygosity mapping revealed a homozygous missense PLXNA2 variant (c.3073G>A / p.(Asp1025Asn), present only once in gnomAD (htz), with rather non-concordant in silico predictions SIFT 0.22, PolyPhen 0.682 and CADD 23.5. The aa was however highly conserved.

Segregation analysis confirmed carrier state of the parents and 2 unaffected sibs, with a 3rd sib homozygous for the wt allele.

As the authors discuss:
*PLXNA2 belongs to the plexin family of genes, encoding transmbembrane proteins functioning as semaphorin receptors. It has predominant expression in neural tissue. The protein is thought to bind semaphorin-3A, -3C or -5 followed by plexin A2 dimerization, activation of its GTPase-activating protein domain, negative regulation of Rap1B GTPase and initiation of a signal transduction cascade mediating axonal repulsion/guidance, dendritic guidance, neuronal migration.
*Murine Plxna2 knockout models display structural brain defects. In addition they display congenital heart defects incl. persistent truncus arteriosus and interrupted aortic arch.
*Rare CNVs in adult humans with tetralogy of Fallot have suggested a potential role of PLXNA2 in cardiac development and CHD.
*Expression and the role of PLXNA2 in human chondrocytes as well as a GWAS in 240 japanese patients with mandibular prognathism where PLXNA2 was suggested as a susceptibility locus.

Overall, the authors recognize some common features (as for cognitive functioning, some dysmorphic features incl. obtuse mandibular angle and overbite in 2 unrelated subjects, failure to thrive 3/3) and provide plausible explanations for the variability / discordance of others eg:
- Cyanotic heart disease explaining discordance in cognitive outcome among sibs
- Incomplete penetrance for CHD (and/or ID or mandibular anomaly) as for few AR disorders and/or
- Additional pathogenic variants possibly explaining the CHD in the first subject.

There is no associated phenotype in OMIM or G2P. SysID includes PLXNA2 among the candidate ID genes.

Review for gene: VPS50 was set to AMBER
Added comment: Schneeberger et al (2021 - PMID: 34037727) describe the phenotype of 2 unrelated individuals with biallelic VPS50 variants.

Common features included transient neonatal cholestasis, failure to thrive, severe DD with failure to achieve milestones (last examination at 2y and 2y2m respectively), postnatal microcephaly, seizures (onset at 6m and 25m) and irritability. There was corpus callosum hypoplasia on brain imaging.

Both individuals were homozygous for variants private to each family (no/not known consanguinity applying to each case). The first individual was homozygous for a splicing variant (NM_017667.4:c.1978-1G>T) and had a similarly unaffected sister deceased with no available DNA for testing. The other individual was homozygous for an in-frame deletion (c.1823_1825delCAA / p.(Thr608del)).

VPS50 encodes a critical component of the endosome-associated recycling protein (EARP) complex, which functions in recycling endocytic vesicles back to the plasma membrane [OMIM based on Schindler et al]. The complex contains VPS50, VPS51, VPS52, VPS53, the three latter also being components of GARP (Golgi-associated-retrograde protein) complex. GARP contains VPS54 instead of VPS50 and is required for trafficking of proteins to the trans-golgi network. Thus VPS50 (also named syndetin) and VPS54 function in the EARP and GARP complexes, to define directional movement of their endocytic vesicles [OMIM based on Schindler et al]. The VPS50 subunit is required for recycling of the transferrin receptor.

As discussed by Schneeberger et al (refs provided in text):
- VPS50 has a high expression in mouse and human brain as well as throughout mouse brain development.
- Mice deficient for Vps50 have not been reported. vps50 knockdown in zebrafish results in severe developmental defects of the body axis. Knockout mice for other proteins of the EARP/GARP complex (e.g. Vps52, 53 and 54) display embryonic lethality.

Studies performed by Schneeberger et al included:
- Transcript analysis for the 1st variant demonstrated skipping of ex21 (in patient derived fabriblasts) leading to an in frame deletion of 81 bp (r.1978_2058del) with predicted loss of 27 residues (p.Leu660_Leu686del).
- Similar VPS50 mRNA levels but significant reduction of protein levels (~5% and ~8% of controls) were observed in fibroblasts from patients 1 and 2. Additionally, significant reductions in the amounts of VPS52 and VPS53 protein levels were observed despite mRNA levels similar to controls. Overall, this suggested drastic reduction of functional EARP complex levels.
- Lysosomes appeared to have similar morphology, cellular distribution and likely unaffected function in patient fibroblasts.
- Transferrin receptor recycling was shown to be delayed in patient fibroblasts suggestive of compromise of endocytic-recycling function.

As the authors comment, the phenotype of both individuals with biallelic VPS50 variants overlaps with the corresponding phenotype reported in 15 subjects with biallelic VPS53 or VPS51 mutations notably, severe DD/ID, microcephaly and early onset epilepsy, CC anomalies. Overall, for this group, they propose the term "GARP and/or EARP deficiency disorders".

There is no VPS50-associated phenotype in OMIM or G2P. SysID includes VPS50 among the ID candidate genes.

Mendeliome v0.8657 ACAN Zornitza Stark edited their review of gene: ACAN: Added comment: Patients with SSOAD exhibit a broad phenotypic spectrum involving short stature associated with advanced bone maturation and early-onset osteoarthritis (OA), as well as mild dysmorphic features consisting of midface hypoplasia, brachydactyly, broad great toes, and lumbar lordosis. Other features include intervertebral disc disease and osteochondritis dissecans, which is characterized by separation of articular cartilage and subchondral bone from the articular surface. Phenotypes are highly variable even among patients within the same family, and there are no apparent genotype-phenotype correlations.

Well established gene-disease association, multiple families reported.

Mendeliome v0.8583 PRDX3 Hazel Phillimore changed review comment from: Biallelic variants in 5 unrelated families with early onset (median 21 years , range 13-22 years) with ataxia with variable additional hyper- and hypokinetic movement disorders, and severe early-onset cerebellar atrophy (seen on MRI), and involvement of the brainstem, medullary olive and parietal cortex.
Evolution of the disease was gait ataxia leading to upper limb ataxia, then dysarthria and then dysphagia, all within a decade. For some of these patients, the phenotype included myoclonus, dystonia and / or tremor. Mild classical mitochondrial features were seen in one of the patients, namely ptosis and COX-negative fibres.
The variants were homozygous nonsense, homozygous frameshift, homozygous missense, and a compound heterozygote of a splice variant and missense, all leading to complete loss of the protein. Oxidative stress and mitochondrial dysfunction was indicated as the disease mechanism.
The families originated from Germany, France, India and two from eastern Turkey. The two families from Turkey were seemingly unrelated to each other but had the same homozygous missense.
Patient fibroblasts from each of the five probands showed lack of protein (via Western blot) and decreased glutathione peroxidase activity and decreased mitochondrial maximal respiratory capacity.
PRXD3 encodes peroxiredoxin 3, a mitochondrial antioxidant protein, that catalyses the reduction of hydrogen peroxide. It localises in the mitochondria, where most hydrogen peroxide is generated.
Functional studies: PRDX3 knockdown (induced by silencing RNA against PRDX3) in cerebellar medulloblastoma cells showed significantly decreased cell viability, increased hydrogen peroxide levels and increased susceptibility to apoptosis triggered by reactive oxygen species.
In addition, induced knockdown drosophila (in vivo animal model) had aberrant locomotor phenotypes and reduced lifespans, while immunolabelling of the brain showed increased cell death after exposure to oxidative stress.

Added comment: Semino et al (2021 - PMID: 34157790) provide clinical details on 3 unrelated individuals with de novo SYNCRIP variants and provide a review of 5 additional subjects previously identified within large cohorts in the literature and databases.

Features included DD, ID (7/7 for whom this information was available), ASD or autistic features (4/7). MRI abnormalities were observed in 3 (widening of CSF spaces, periventricular nodular heterotopia, prominent lat. ventricles). Epilepsy (myoclonic-astatic epilepsy / Doose syndrome) was reported for 2(/8) individuals.

The 3 patients here reported were identified following trio/singleton exome with Sanger confirmation of the variants and their de novo occurrence.

Variants are in almost all cases de novo (7/7 for whom this was known) and in 5/8 cases were pLoF, in 2/8 missense SNVs while a case from DECIPHER had a 77.92 kb whole gene deletion not involving other genes with unknown inheritance.

Overall the variants reported to date include [NM_006372.5]:
1 - c.858_859del p.(Gly287Leufs*5)
2 - c.854dupA p.(Asn285Lysfs*8)
3 - c.734T>C p.(Leu245Pro)

SYNCRIP (also known as HNRNPQ) encodes synaptotagmin‐binding cytoplasmic RNA‐interacting protein. As the authors note, this RNA-binding protein is involved in multiple pathways associated with neuronal/muscular developmental disorders. Several references are provided for its involvement in regulation of RNA metabolism, among others sequence recognition, pre-mRNA splicing, translation, transport and degradation.

Mutations in other RNA-interacting proteins and hnRNP members (e.g. HNRNPU, HNRNPD) are associated with NDD.

The missense variant (p.Leu245Pro) is within RRM2 one of the 3 RNA recognition motif (RRM) domains of the protein. These 3 domains, corresponding to the central part of the protein (aa 150-400), are relatively intolerant to variation (based on in silico predictions and/or variation in gnomAD). Leu245 localizes within an RNA binding pocket and in silico modeling suggests alteration of the tertiary structure and RNA-binding capacity of RRM2.

There are no additional studies performed.

Overall haploinsufficiency appears to be the underlying disease mechanism based on the truncating variants and the gene deletion. [pLI in gnomAD : 1, %HI : 2.48%]

Animal models are not discussed.

There is no associated phenotype in OMIM. This gene is included in the DD panel of G2P (monoallelic LoF variants / SYNCRIP-related developmental disorder). SysID also lists SYNCRIP within the current primary ID genes.

Added comment: 3 publications by Zech et al (2018, 2020 - PMIDs : 30262571, 33098801, 33211350) provide clinical details on 3 individuals, each harboring a private de novo CAMK4 variant.

Overlapping features included DD, ID, behavoral issues, autism and abnormal hyperkinetic movements. Dystonia and chorea in all 3 appeared 3-20 years after initial symptoms.

CAMK4 encodes Calcium/Calmodulin-dependent protein kinase IV, an important mediator of calcium-mediated activity and dynamics, particularly in the brain. It is involved in neuronal transmission, synaptic plasticity, and neuronal gene expression required for brain development and neuronal homeostasis (summary by OMIM based on Zech et al, 2018).

The 473 aa enzyme has a protein kinase domain (aa 46-300) and a C-terminal autoregulatory domain (aa 305-341) the latter comprising an autoinhibitory domain (AID / aa 305-321) and a calmodulin-binding domain (CBD / aa 322-341) [NP_001735.1 / NM_001744.4 - also used below].

Variants in all 3 subjects were identified following trio-WES and were in all cases protein-truncating, mapping to exon 10 or exon 10-intron 10 junction, expected to escape NMD and cause selective abrogation of the autoinhibitory domain (aa 305-321) leading overall to gain-of-function.

Variation databases include pLoF CAMK4 variants albeit in all cases usptream or downstream of this region (pLI of this gene in gnomAD: 0.51). Variants leading to selective abrogation of the autoregulatory domain have not been reported.

Extensive evidence for the GoF effect of the variant has been provided in the first publication. Several previous studies have demonstrated that abrogation of the AID domain leads to consitutive activation (details below).

Mouse models - though corresponding to homozygous loss of function - support a role for CAMKIV in cognitive and motor symptoms. Null mice display tremulous and ataxic movements, deficiencies in balance and sensorimotor performance associated with reduced number of Purkinje neurons (Ribar et al 2000, PMID: 11069976 - not reviewed). Wei et al (2002, PMID: 12006982 - not reviewed) provided evidence for alteration in hippocampal physiology and memory function.

Heterozygous mutations in other genes for calcium/calmodulin-dependent protein kinases (CAMKs) e.g. CAMK2A/CAMK2B (encoding subunits of CAMKII) have been reported in individuals with ID.

---

The proband in the first publication (PMID: 30262571) was a male with DD, ID, behavioral difficulties (ASD, autoaggression, stereotypies) and hyperkinetic movement disorder (myoclonus, chorea, ataxia) with severe generalized dystonia (onset at the age of 13y). Brain MRI demonstrated cerebellar atrophy.

Extensive work-up incl. karyotyping, CMA, DYT-TOR1A, THAP1, GCH1, SCA1/2/3/6/7/8/12/17, Friedreich's ataxia and FMR1 analysis was negative.F

Trio WES identified a dn splice site variant (c.981+1G>A) in the last exon-intron junction. RT-PCR followed by gel electrophoresis and Sanger in fibroblasts from an affected and control subject revealed that the proband had - as predicted by the type/location of the variant - in equal amount 2 cDNA products, a normal as well as a truncated one.

Sequencing of the shortest revealed utilization of a cryptic donor splice site upstream of the mutated donor leading to a 77bp out-of-frame deletion and introduction of a premature stop codon in the last codon (p.Lys303Serfs*28). Western blot in fibroblast cell lines revealed 2 bands corresponding to the normal protein product as well as to the p.Lys303Serfs*28 although expression of the latter was lower than that of the full length protein.

Several previous studies have shown that mutant CAMKIV species that lack the autoinhibitory domain are consitutively active (several Refs provided). Among others Chatila et al (1996, PMID: 8702940) studied an in vitro-engineered truncation mutant (Δ1-317 - truncation at position 317 of the protein) with functionally validated gain-of-function effect.

To prove enhanced activity of the splicing variant, Zech et al assessed phosphorylation of CREB (cyclic AMP-responsive element binding protein), a downstream substrate of CAMKIV. Immunobloting revealed significant increase of CREB phosphorylation in patient fibroblasts compared to controls. Overactivation of CAMKIV signaling was reversed when cells were treated with STO-609 an inhibitor of CAMKK, the ustream activator of CAMKIV.

Overall the authors demonstrated that loss of CAMKIV autoregulatory domain due to this splice variant had a gain-of-function effect.

----

Following trio-WES, Zech et al (2020 - PMID: 33098801) identified another relevant subject within cohort of 764 individuals with dystonia. This 12-y.o. male, harboring a different variant affecting the same donor site (c.981+1G>T), presented DD, ID, dystonia (onset at 3y) and additional movement disorders (myoclonus, ataxia) as well as similar behavior (ASD, autoaggression, stereotypies). [Details in suppl. p20].

----

Finally Zech et al (2020 - PMID: 33211350) reported on a 24-y.o. woman with adolescence onset choreodystonia. Other features included DD, moderate ID, absence seizures in infancy, OCD with anxiety and later diagnosis of ASD. Trio WES revealed a dn stopgain variant (c.940C>T; p.Gln314*).

Cone dystrophy
-------------------
PMID: 33891002 - Khol et al 2021 - report 3 unrelated families with duplications of a region covering the genes IRX5 and IRX6 completely, and the proximal exons of MMP2 and cone dystrophy. They propose that overexpression of IRX5 and IRX6 may be the cause of the disease, and this is supported by expression analysis in patient-derived fibroblasts and zebrafish experiments.

Initial family is a large 5 generation German family with 14 members with autosomal dominant cone dystrophy in which a 600kb duplicated region covering IRX5/IRX6 and part of MMP2 was identified. 2 additional families of Chinese and Dutch descent with copy number gains of ~700 and ~850 kb, covering the same region were then identified. The smallest region of overlap is 608kb. In addition another family of German decent is reported with adCD and the same duplication as the first German family. It is not known if they are distantly related. Segregation analysis on available members of all families showed the duplication in affected members and not in unaffected.

They find that IRX5, IRX6 and MMP2 are expressed in human adult retina. Several lincRNA within the locus are also expressed. In patient derived fibroblasts IRX5 and IRX6 showed increased expression levels.

Review for gene: EPHA7 was set to AMBER
Added comment: Lévy et al (2021 - PMID: 34176129) provide evidence that haploinssuficiency of EPHA7 results in a neurodevelopmental disorder.

The authors report on 12 individuals belonging to 9 unrelated families, all harboring with 6q microdeletions spanning EPHA7.

Overlapping features included DD (13/13), ID (10/10 - mild in most cases, individuals with larger CNVs/additional variants had more severe phenotype), speech delay and behavioral disorders. Variable other features incl. hypotonia (70%), non specific facial features, eye abnormalities (40%) and cardiac defects (25%).

The CNVs ranged from 152 kb to few Mb in size but in 4 subjects (P5-8) were only minimal, involving only EPHA7.

9 out of 12 individuals had inherited the deletion (5 subjects paternal, 4 maternal), in 1 subject (P12) this occured de novo, while for 2 others inheritance was not specified. Most deletions were inherited from an unaffected parent (in 6/7 families), with unclear contribution in a further one.

The authors discuss on previous studies suggesting an important role for EphA7 in brain development (modulation of cell-cell adhesion and repulsion, regulation of dendrite morphogenesis in early corticogenesis, role in dendritic spine formation later in development. EphA7 has also been proposed to drive neuronal maturation and synaptic function).

Haploinsufficiency for other ephrins or ephrin receptors has been implicated in other NDDs.

Overall Lévy et al promote incomplete penetrance and variable expressivity with haploinsufficiency of this gene being a risk factor for NDD. [The gene has also an %HI of 2.76% and a pLI of 1].

Mendeliome v0.7905 PLG Zornitza Stark changed review comment from: Association between mono-allelic variants and HAE: Over 20 families reported with a recurrent variant, p.Lys330Glu. Single family reported with a different variant. Note bi-allelic variants are associated with a separate disorder.

Bi-allelic variants and plasminogen deficiency: congenital plasminogen deficiency is characterised clinically by chronic mucosal pseudomembranous lesions consisting of subepithelial fibrin deposition and inflammation. The most common clinical manifestation is ligneous ('wood-like') conjunctivitis, a redness and subsequent formation of pseudomembranes mostly on the palpebral surfaces of the eye that progress to white, yellow-white, or red thick masses with a wood-like consistency that replace the normal mucosa. The lesions may be triggered by local injury and/or infection and often recur after local excision. Pseudomembranous lesions of other mucous membranes often occur in the mouth, nasopharynx, trachea, and female genital tract. Some affected children also have congenital occlusive hydrocephalus. At least 3 unrelated families reported.; to: Association between mono-allelic variants and HAE: Over 20 families reported with a recurrent variant, p.Lys330Glu.

Afibrinogenaemia is characterized by the complete absence of immunoreactive fibrinogen. Bleeding due to afibrinogenaemia usually manifests in the neonatal period, with 85% of cases presenting umbilical cord bleeding, but a later age of onst is not unusual. Bleeding may occur in the skin, gastrointestinal tract, genitourinary tract, or the central nervous system, with intracranial haemorrhage being reported as the major cause of death. Patients are susceptible to spontaneous rupture of the spleen. First-trimester pregnancy loss is common. Both arterial and venous thromboembolic complications have been reported. Hypofibrinogenaemia is a milder disorder.

Added comment: MCM7 is a component of the MCM complex, a DNA helicase which is essential for DNA replication. Other components have been linked to disease with phenotypes including microcephaly and ID. MCM7 is not associated with any phenotype in OMIM or G2P at present.
------
Currently there are 3 unrelated pedigrees in literature with different biallelic MCM7 variants associated with disease (see below). Although there is some functional data in support of variant-level deleteriousness or gene-level pathogenicity, the clinical gestalt is very different between the 3 families.

- PMID: 33654309 (2021) - Two unrelated individuals with different compound het variants in MCM7 but disparate clinical features. One patient had typical Meier-Gorlin syndrome (including growth retardation, microcephaly, congenital lung emphysema, absent breast development, microtia, facial dysmorphism) whereas the second case had a multi-system disorder with neonatal progeroid appearance, lipodystrophy and adrenal insufficiency. While small at birth, the second patient did not demonstrate reduced stature or microcephaly at age 14.5 years. Both individuals had normal neurodevelopment.
Functional studies using patient-derived fibroblasts demonstrate that the identified MCM7 variants were deleterious at either transcript or protein levels and through interfering with MCM complex formation, impact efficiency of S phase progression.

- PMID: 34059554 (2021) - Homozygous missense variant identified in three affected individuals from a consanguineous family with severe primary microcephaly, severe ID and behavioural abnormalities. Knockdown of Mcm7 in mouse neuroblastoma cells lead to reduced cell viability and proliferation with increased apoptosis, which were rescued by overexpression of wild-type but not mutant MCM7.

Bi-allelic variants include 10 missense variants that disrupt highly conserved amino acids, a nonsense variant, two frameshift variants, an in-frame deletion, and a microdeletion encompassing JAG2. Onset of muscle weakness occurred from infancy to young adulthood. Serum creatine kinase (CK) levels were normal or mildly elevated. Muscle histology was primarily dystrophic. MRI of the lower extremities revealed a distinct, slightly asymmetric pattern of muscle involvement with cores of preserved and affected muscles in quadriceps and tibialis anterior, in some cases resembling patterns seen in POGLUT1-associated muscular dystrophy.

All affected individuals presented with a progressive neurodevelopmental disorder consisting of cognitive impairment, cerebellar atrophy/hypoplasia, motor dysfunction with ataxia and dystonia, and nystagmus. Zebrafish disease modelling supports the involvement of VPS41 dysfunction in the disorder, indicating lysosomal dysregulation throughout the brain and providing support for cerebellar and microglial abnormalities when vps41 was mutated. This provides the first example of human disease linked to the HOPS-specific subunit VPS41 and suggests the importance of HOPS complex activity for cerebellar function."; to: "Five unrelated families with nine affected individuals, all carrying homozygous variants in VPS41 that we show impact protein function.

"Affected individuals were born after uneventful pregnancies and presented in most cases early in life with developmental delay. Various degrees of ataxia, hypotonia, and dystonia were present in all affected individuals, preventing independent ambulation. Likewise, nystagmus was commonly described. In addition, all affected individuals displayed intellectual disability and speech delay. Two siblings further presented with therapy-resistant epilepsy. No major dysmorphic features were found. In two individuals, retinal pigment alterations were noticed. Brain MRI revealed mild cerebellar atrophy and vermian atrophy without other major structural abnormalities in most affected individuals while in one case (Subject 9) bilateral hyperintensities at the nucleus caudatus area were noted. No hearing or vision problems were noted and in cases where nerve conduction studies were performed, these were normal. Transmission electron microscopy (TEM) on peripheral blood lymphocytes from Subject 2 and lymphoblastoid cells from Subject 3 revealed more multilayered vesicles compared to control cells."

Mendeliome v0.7249 NDUFB11 Kristin Rigbye changed review comment from: Variable syndromic features have been observed in affected individuals, however anaemia and cardiomyopathy appear to be consistent features in males and females, respectively (PMID: 28050600, PMID: 30423443, PMID: 27488349).

Affected females have previously been reported with inherited pathogenic variants from their unaffected mothers. It has been suggested that this may be due to patterns of somatic X-chromosome inactivation, mosaicism or additional genetic or external factors (PMID: 28050600).

Affected females have been reported with null alleles, whereas affected males have only been identified with missense variants or a recurrent single residue in-frame deletion, suggesting that some residual enzyme activity is required for males to be viable, whereas complete loss of function variants may be lethal when hemizygous (PMID: 30423443).
Note: female carriers of missense variants have not been reported as clinically affected.

Western blots from cells of male patients with the recurrent F93del variant showed reduced protein levels, and recombinant cells demonstrated a proliferation defect, consistent with the anaemia phenotype (PMID: 27488349).; to: Variable syndromic features have been observed in affected individuals, however anaemia and cardiomyopathy appear to be consistent features in males and females, respectively (PMID: 28050600, PMID: 30423443, PMID: 27488349).

It has been suggested that heterozygous females do not display the severe phenotype associated with mitochondrial complex 1 deficiency due to highly skewed XCI favouring expression of the wild type allele, whereas these null variants result in a severe lethal disorder in hemizygous males (PMID: 25772934).

Affected females have previously been reported with inherited pathogenic variants from their unaffected mothers. It has been suggested that this may be due to patterns of somatic X-chromosome inactivation, mosaicism or additional genetic or external factors (PMID: 28050600).

- PMID: 29016857 (2017) - Homozygosity mapping of disease loci combined with WES in a single male from a consanguineous family presenting with lethal AMC revealed a homozygous frameshift deletion in UNC50 gene (c.750_751del:p.Cys251Phefs*4). Functional studies in C. elegans showed the variant caused loss of acetylcholine receptor expression in the muscle.

- PMID: 33820833 (2021) - Single individual reported with the same homozygous c.750_751del:p.Cys251Phefs*4 variant in UNC50 as previously described. The case was identified from a cohort of 315 genetically undiagnosed and unrelated AMC families. Arthrogryposis and tetra ventricular dilation were detected prenatally.

-- Note: it isn't definitively clear whether these are different individuals. Both are singleton males born to consanguineous parents, with the same variant and similar phenotype. Also both infants died at 28 w.g. However, the 2021 paper (PMID:33820833) states their patient was selected from a cohort of cases without a molecular diagnosis and indicate the UNC50 gene had already previously been identified in relation to this phenotype, highlighting the earlier paper (PMID:29016857). There is also no mention of tetra ventricular dilation in the first case, so it is likely that these do represent distinct individuals. Additional cases needed to provide clarity.

1 case with asphyxiating thoracic dystrophy (ATD) syndrome and infantile‐onset diabetes. Whole exome sequencing revealed a homozygous frameshift variant in the PDIA6 gene. RNA expression was reduced in a gene dosage‐dependent manner, supporting a loss‐of‐function effect of this variant. Phenotypic correlation with the previously reported mouse model recapitulated the growth defect and delay, early lethality, coagulation, diabetes, immunological, and polycystic kidney disease phenotypes. The phenotype of the current patient is consistent with phenotypes associated with the disruption of PDIA6 and the sensors of UPR in mice and humans.

Added comment: An 8‐months‐old male with developmental delay, microcephaly, subtle dysmorphism, hypotonia, pontocerebellar hypoplasia and delayed myelination. Similarly affected elder sibling succumbed at the age of 4‐years 6‐months. Exome sequencing revealed a homozygous missense variant (c.104C >T, p.Ser35Leu) in EXOSC1. In silico mutagenesis revealed loss of a polar contact with neighbouring Leu37 residue. Quantitative real‐time PCR indicated no appreciable differences in EXOSC1 transcript levels. Immunoblotting and blue native PAGE revealed reduction in the EXOSC1 protein levels and EXO9 complex in the proband, respectively. Of note, bi‐allelic variants in other exosome subunits EXOSC3, EXOSC8 and EXOSC9 have been reported to cause pontocerebellar hypoplasia type 1B, type 1C and type 1D, respectively.

Danon disease is an X-linked dominant disorder predominantly affecting cardiac muscle. Skeletal muscle involvement and mental retardation are variable features. The accumulation of glycogen in muscle and lysosomes originally led to the classification of Danon disease as a variant of glycogen storage disease II (Pompe disease) with 'normal acid maltase' or alpha-glucosidase, however, it may be more accurately classified as a lysosomal disorder.

Review for gene: VWA1 was set to GREEN
Added comment: Six different truncating variants identified in 15 affected individuals from six families (biallelic inheritance). Disease manifested in childhood or adulthood with proximal and distal muscle weakness predominantly of the lower limbs. Myopathological and neurophysiological findings were indicative of combined neurogenic and myopathic pathology. Early childhood foot deformity was frequent, but no sensory signs were observed.

An additional 17 individuals from 15 families with hereditary motor neuropathy were identified. A 10-bp repeat expansion at the end of exon 1 was observed in 14 families and was homozygous in 10 of them. This mutation, c.62_71dup [p.Gly25Argfs*74], leads to a frameshift that results in a reduction in VWA1 transcript levels via nonsense-mediated decay.

Mendeliome v0.7004 PRIM1 Zornitza Stark changed review comment from: - PMID: 33060134 (2020) - From a cohort of 220 families with microcephalic dwarfism spectrum disorders (OFC ≤−4 SD; height ≤−2 SD), three families (4 individuals) were identified with the same homozygous intronic variant (c.638+36C>G) in PRIM1. This variant was present in gnomAD in 2 individuals across all populations, but only in a heterozygous state. Haplotype analysis indicated that all three families share a distant common ancestor - i.e. confirmed founder variant.
Authors subsequently identified a single individual with compound heterozygous PRIM1 variants (c.103+1G>T, c.901T>C) from the DDD study, who also presented microcephaly and short stature (OFC ≤−3 SD; height ≤−3 SD).

Clinical overlap was evident in all 5 individuals, presenting extreme pre- and postnatal growth restriction, severe microcephaly (OFC −6.0 ± 1.5 SD) with simplified gyri appearance, hypothyroidism, hypo/agammaglobulinaemia, and lymphopaenia accompanied by intermittent anaemia/thrombocytopaenia. All had chronic respiratory symptoms, and four died in early childhood from respiratory or GI infections.

Functional studies demonstrated reduced PRIM1 protein levels, replication fork defects and prolonged S-phase duration in PRIM1-deficient cells. The resulting delay to the cell cycle and inability to sustain sufficient cell proliferation provides a likely mechanism for the presenting phenotype.

This variant was present in gnomAD in 2 individuals across all populations, but only in a heterozygous state. Haplotype analysis indicated that all three families share a distant common ancestor - i.e. confirmed founder variant.
Authors subsequently identified a single individual with compound heterozygous PRIM1 variants (c.103+1G>T, c.901T>C) from the DDD study, who also presented microcephaly and short stature (OFC ≤−3 SD; height ≤−3 SD).

Clinical overlap was evident in all 5 individuals, presenting extreme pre- and postnatal growth restriction, severe microcephaly (OFC −6.0 ± 1.5 SD) with simplified gyri appearance, hypothyroidism, hypo/agammaglobulinemia, and lymphopenia accompanied by intermittent anaemia/thrombocytopaenia. All had chronic respiratory symptoms, and four died in early childhood from respiratory or GI infections.

Mendeliome v0.6808 SATB1 Zornitza Stark edited their review of gene: SATB1: Added comment: Kohlschutter-Tonz syndrome-like (KTZSL) is characterized by global developmental delay with moderately to severely impaired intellectual development, poor or absent speech, and delayed motor skills. Although the severity of the disorder varies, many patients are nonverbal and have hypotonia with inability to sit or walk. Early-onset epilepsy is common and may be refractory to treatment, leading to epileptic encephalopathy and further interruption of developmental progress. Most patients have feeding difficulties with poor overall growth and dysmorphic facial features, as well as significant dental anomalies resembling amelogenesis imperfecta. This phenotype was reported in 28 patients (patients 13 to 40, PMID 33513338), including 9 patients from 3 families. Most variants were de novo, though some were inherited, suggestive of incomplete penetrance and variable expressivity.; Changed phenotypes: Developmental delay with dysmorphic facies and dental anomalies, MIM# 619228, Kohlschutter-Tonz syndrome-like, MIM# 619229

Added comment: Immunodeficiency-77 (IMD77) is an immunologic disorder characterized by recurrent and persistent polymicrobial infections with multiple unusual organisms. Skin and pulmonary infections are the most common, consistent with increased susceptibility to epithelial cell infections. The age at onset is highly variable: some patients have recurrent infections from childhood, whereas others present in late adulthood. The limited number of reported patients are all female, suggesting incomplete penetrance or a possible sex-influenced trait. Patient cells, mainly macrophages, show impaired killing of intracellular bacteria and organisms, including nontubercular mycobacteria, although there is also impaired killing of other organisms, such as Pseudomonas, Candida, and Aspergillus.

Four individuals reported, functional data, including animal model.

Added comment: - PMID: 32439808 (2021) - Three generation family with c.350T>C variant in APOO, encoding a component of the MICOS complex which plays a role in maintaining inner mitochondrial membrane architecture.
Phenotypes include fatigue and muscle weakness (6/8), learning difficulties and cognitive impairment (4/8), and increased blood lactate (2/8). Four individuals were asymptomatic carriers, including one male (authors indicate variability in female carriers was due to skewed X-inactivation, although skewing studies were inconclusive in some cases). Variability in clinical presentation suggests reduced penetrance or possible contribution of additional factors.
Functional studies showed altered MICOS assembly and abnormalities in mitochondria ultrastructure in patient-derived fibroblasts. Knockdown studies in Drosophila and yeast demonstrated mitochondrial structural and functional deficiencies.

Added comment: PMID: 26068709 - Three siblings in a single consanguineous family with congenital insensitivity to pain, inability to feel touch, and cognitive delay and a homozygous rare missense variant (Glu330Lys - no homozygotes in gnomAD v2.1). In vitro functional assays of the variant suggested a deleterious effect on the protein. Additionally cellular assays suggested a role for the gene in neural crest development and in the genesis of pain and touch sensing neurons.

PMID: 29402896 - more in depth functional assays and proteomic analyses suggesting a role for the protein in regulating sensory neuron differentiation in the human peripheral system

Other reports of associations with limited evidence:
PMID: 22511880 - Identified as a candidate gene in an autism study, but the homozygous variant (reported as R125C, but actually R1165C) has 40 homozygotes in gnomAD v2.1. And many of the other compound heterozygous candidate variants in the study are too common in gnomAD v2.1, with many homozygotes present. The missense reported in the pain insensitivity family Glu330Lys was reported with another rare missense variant (Glu1310Lys) in one of the autism cases, but no other phenotype information was provided.

PMID: 31354784 - a single case with infantile spasm reported with compound het missense (Met1316Val & Arg1165Cys), but both are very common in gnomAD v2.1 with 33,000 and 40 homozygotes, respectively.

However, Fstl5 was expressed more highly in neural tissues in mice, and rats lacking Fstl5 showed no gross developmental malformations. Conditional overexpression of Fstl5 in osteochondroprogenitors resulted in sexually dimorphic differences in skeletal development in mice.

Added comment: A very large family affected by CHD and familial thoracic aortic aneurysms. Trio genome sequencing was carried out in an index patient with critical CHD, and family members had either exome or Sanger sequencing. Identified homozygous loss-of-function variant (c.318_319delAG, p.G108*) in HEY2 in 3 individuals in family with critical CHD, whereas the 20 heterozygous carriers show a spectrum of CVDs (CHD and FTAA, but varying expressivity and incomplete penetrance). Other studies show that knockout of HEY2 in mice results in cardiovascular defects (CVDs), including septal defects, cardiomyopathy, a thin-walled aorta, and valve anomalies.

Added comment: 5 sibs from a consanguineous family identified to have biallelic deletion encompassing part of the PYCR1 gene and the coding region of the MYADML2 gene.

According to the authors: "All five affected sibs had the most common features of ARCL (autosomal recessive cutis laxa) but not many of the less common ones. We attributed the anomalies not typical for ARCL to MYADML2 deficit, because no other genetic defect possibly a candidate to underlie the skeletal phenotype was found."

Phenotype may still be explained by the PYCR1 deletion alone.

Mendeliome v0.6149 NOS1AP Zornitza Stark edited their review of gene: NOS1AP: Added comment: Nephrotic syndrome type 22 (NPHS22) is an autosomal recessive renal disease characterized by onset of progressive kidney dysfunction in infancy. Affected individuals usually present with edema associated with hypoproteinemia, proteinuria, and microscopic hematuria. Renal biopsy shows effacement of the podocyte foot processes, glomerulosclerosis, and thickening of the glomerular basement membrane. The disease is steroid-resistant and progressive, resulting in end-stage renal disease usually necessitating kidney transplant.

Mendeliome v0.6119 FOXF1 Zornitza Stark changed review comment from: Congenital alveolar capillary dysplasia with misalignment of pulmonary veins (ACDMPV) is characterized histologically by failure of formation and ingrowth of alveolar capillaries that then do not make contact with alveolar epithelium, medial muscular thickening of small pulmonary arterioles with muscularization of the intraacinar arterioles, thickened alveolar walls, and anomalously situated pulmonary veins running alongside pulmonary arterioles and sharing the same adventitial sheath. Less common features include a reduced number of alveoli and a patchy distribution of the histopathologic changes. The disorder is associated with persistent pulmonary hypertension of the neonate and shows varying degrees of lability and severity. Affected infants present with respiratory distress resulting from pulmonary hypertension in the early postnatal period, and the disease is uniformly fatal within the newborn period. Additional features of ACDMPV include multiple congenital anomalies affecting the cardiovascular, gastrointestinal, genitourinary, and musculoskeletal systems, as well as disruption of the normal right-left asymmetry of intrathoracic or intraabdominal organs.; to: Congenital alveolar capillary dysplasia with misalignment of pulmonary veins (ACDMPV) is characterized histologically by failure of formation and ingrowth of alveolar capillaries that then do not make contact with alveolar epithelium, medial muscular thickening of small pulmonary arterioles with muscularization of the intraacinar arterioles, thickened alveolar walls, and anomalously situated pulmonary veins running alongside pulmonary arterioles and sharing the same adventitial sheath.

PMID: 21666694 - Lipoprotein profiles of the families of 4 individuals with CREB3L3 nonsense mutations showed a significantly elevated mean plasma TG level in 11 mutation carriers compared with 5 non-carrier first-degree relatives (9.67 ± 4.70 vs. 1.66 ± 0.55 mM, P = 0.021, Wilcoxon test). 3 of those families have the same variant - Lys245GlufsTer130, which has 126 (281,946 alleles) hets in gnomAD v2.1.
PMID: 32580631 - case-control analysis of nonmonogenic severe hypertriglyceridemia cases (N=265) vs normolipidemic controls (N=477), identified 5 cases with LoF variants (3 of whom had the Lys245GlufsTer130 frameshift) and none in controls. OR 20.2 (95% CI 1.11–366.1) p = 0.002, adjusted p = 0.03.
The frequency of Lys245GlufsTer130 is higher than expected for a dominant disorder, but other loss of function variants have been identified. The gene may be associated with variable penetrance. There are multiple supporting null mouse models with hyperlipidaemia.

Added comment: Three cases in two unrelated consanguineous families with homozygous loss of function variants. Multiple null model organisms recapitulate the human phenotype: Null mouse model had cystic kidneys, a phenotype common to ciliopathies. Reducing Cby levels in Xenopus laevis model reduced the density of multiciliated cells, the number of basal bodies per multiciliated cell, and the numbers of neural tube primary cilia; it also led to abnormal development of the neural crest, central nervous system, and pronephros. Depletion of cby1 in zebrafish results in ciliopathy‐related phenotypes.

Review for gene: FKBP8 was set to AMBER
Added comment: Not associated with a phenotype in OMIM.

PMID: 32969478 - Tian et al 2020 - performed Sanger sequencing of FKBP8 on DNA samples from 472 spina bifida (SB) affected fetuses and 565 unaffected controls. 5 different rare heterozygous variants (MAF ≤ 0.001) were identified among the SB patients, while no deleterious rare variants were identified in the controls. 4 of the variants are missense, the other is a stop-gain. 2 cases were in white-Hispanic patients while the other 3 were non-white Hispanic. Functional studies showed that p.Glu140* affected FKBP8 localization to the mitochondria and impaired its interaction with BCL2 ultimately leading to an increase in cellular apoptosis. p.Ser3Leu, p.Lys315Asn and p.Ala292Ser variants decreased FKBP8 protein level. Gene expression was studied in mouse Fkbp8-/- embryos and found to be abnormal. Previous mouse models have shown neural tube defects.

Sufficient cases to rate green, but only the FKBP8 gene looked at so perhaps some caution required while further evidence is gathered.

Marbach et al. (2020 - medRxiv : https://doi.org/10.1101/2020.09.10.20190314 - last author : C. Schaaf) report 6 unrelated individuals with heterozygous missense PRKAR1B variants.

All presented formal ASD diagnosis (6/6), global developmental delay (6/6) and intellectual disability (all - formal evaluations were lacking though). Additional features included neurologic anomalies (movement disorders : dyspraxia, apraxia, clumsiness in all, with tremor/dystonia or involuntary movements as single occurrences). Three displayed high pain tolerance. Regression in speech was a feature in two. Additional behavior anomalies included ADHD (4-5/6) or aggression (3/6). There was no consistent pattern of malformations, physical anomalies or facial features (with the exception of uplsanted palpebral fissures reported in 4).

3 different missense variants were identified (NM_00116470:c.1003C>T - p.Arg335Trp, c.586G>A - p.Glu196Lys, c.500_501delAAinsTT - p.Gln167Leu) with Arg355Trp being a recurrent one within this cohort (4/6 subjects). A possible splicing effect may apply for the MNV. All variants are absent from gnomAD and the SNVs had CADD scores > 24.

In all cases were parental samples were available (5/6), the variant had occurred as a de novo event.

Protein kinase A (PKA) is a tetrameric holoenzyme formed by the association of 2 catalytic (C) subunits with a regulatory (R) subunit dimer. Activation of PKA is achieved through binding of 2 cAMP molecules to each R-subunit, and unleashing(/dissociation) of C-subunits to engage substrates. PRKACA/B genes encode the Cα- and Cβ-subunits while the 4 functionally non-redundant regulatory subunits are encoded by PRKAR1A/1B/2A/2B genes. As the authors comment, the RIβ subunit is primarily expressed in brain with higher expression in cortex and hypothalamus.

The functional consequences of the variants at cellular level were not studied.

Previous studies have demonstrated that downregulation of RIβ in murine hippocampal cultures, reduced phosphorylation of CREB, a transcription factor involved in long-term memory formation. The authors speculate that a similar effect on cAMP/PKA/CREB cascade may mediate the cognitive effects in humans. RIβ deficient mice also display diminished nociceptive pain, similar to the human phenotype. [Several refs provided].

The authors cite the study by Kaplanis et al (2020 - PMID: 33057194), where in a large sample of 31,058 trio exomes of children with developmental disorders, PRKAR1B was among the genes with significant enrichment for de novo missense variants. [The gene has a pLI score of 0.18 in gnomAD / o/e = 0.26 - so pLoF variants may not be deleterious].

Please note that a specific PRKAR1B variant (NM_002735.2:c.149T>G - p.Leu50Arg) has been previous reported to segregate with a late-onset neurodegenerative disorder characterized by dementia and/or parkinsonism within a large pedigree with 12 affected individuals [Wong et al 2014 - PMID: 25414040].

Added comment: Sterling et al (2020 - PMID: 33073849) provide information on the phenotype of 3 individuals with de novo MPP5 variants.

Common features included global developmental delay, intellectual disability (3/3 - severe in 2/3), speech delay/regression (the latter in at least 2) and behavioral abnormalities. Variable other features were reported, among others microcephaly (1/3), abnormal vision (1/3 : CVI, retinal dystrophy, nystagmus), brain MRI abnormalities (2/3), late-onset seizures (1/3). These subjects displayed variable and non-specific dysmorphic features.

All were investigated by exome sequencing (previous investigations not mentioned).

One subject was found to harbor a de novo mosaic (5/25 reads) stopgain variant, further confirmed by Sanger sequencing [NM_022474.4:c.1555C>T - p.(Arg519Ter). The specific variant is reported once in gnomAD (1/251338). Two de novo missense variants were identified in the remaining individuals [c.1289A>G - p.Glu430Gly / c.974A>C - p.His325Pro). All variants had in silico predictions in favor of a deleterious effect (CADD score >24).

The authors comment that MPP5 encodes an apical complex protein with asymmetric localization to the apical side of polarized cells. It is expressed in brain, peripheral nervous system and other tissues. MPP5 is a member of the membrane-associated guanylate kinase family of proteins (MAGUK p55 subfamily), determining cell polarity at tight junctions.

Previous animal models suggest that complete Mpp5(Pals1) KO in mice leads to near absence of cerebral cortical neurons. Htz KO display reduction in size of cerebral cortex and hippocampus. The gene is expressed in proliferating cell populations of cerebellum and important for establishment cerebellar architecture. Conditional KO of Mpp5(Pals1) in retinal progenitor cells mimics the retinal pathology observed in LCA. [Several refs. provided]

The authors studied a heterozygous CNS-specific Mpp5 KO mouse model. These mice presented microcephaly, decreased cerebellar volume and cortical thickness, decreased ependymal cells and Mpp5 at the apical surface of cortical vertrical zone. The proportion of cortical cells undergoing apoptotic cell death was increased. Mice displayed behavioral abnormalities (hyperactivity) and visual deficits, with ERG traces further suggesting retinal blindness.

Overall the mouse model was thought to recapitulate the behavioral abnormalities observed in affected subjects as well as individual rare features such as microcephaly and abnormal vision.

Haploinsufficiency (rather than a dominant negative effect) is favored as the underlying disease mechanism. This is also in line with a dose dependent effect observed in mice.

Added comment: Palencia-Campos et al (2020 - PMID: 33058759) report on the phenotype of 3 individuals heterozygous for PRKACA and 4 individuals heterozygous for PRKACB pathogenic variants.

The most characteristic features in all individuals with PRKACA/PRKACB mutation, included postaxial polydactyly of hands (6/7 bilateral, 1/7 unilateral) and feet (4/7 bilateral, 1/7 unilateral), brachydactyly and congenital heart defects (CHD 5/7) namely a common atrium or AVSD. Two individuals with PRKACA variant who did not have CHD had offspring with the same variant and an AVSD.

Other variably occurring features included short stature, limbs, narrow chest, abnormal teeth, oral frenula, nail dysplasia. One individual with PRKACB variant presented tumors.

Intellectual disability was reported in 2/4 individuals with PRKACB variant (1/4: mild, 1/4: severe). The 3 individuals with PRKACA variant did not present ID.

As the phenotype was overall suggestive of Ellis-van Creveld syndrome (or the allelic Weyers acrofacial dysostosis), although these diagnoses were ruled out following analysis of EVC and EVC2 genes.

WES was carried out in all.

PRKACA : A single heterozygous missense variant was identified in 3 individuals from 3 families (NM_002730.4:c.409G>A / p.Gly137Arg) with 1 of the probands harboring the variant in mosaic state (28% of reads) and having 2 similarly affected offspring. The variant was de novo in one individual and inherited in a third one having a similarly affected fetus (narrow thorax, postaxial polyd, AVSD).

PRKACB : 4 different variants were identified (NM_002731.3: p.His88Arg/Asn, p.Gly235Arg, c.161C>T - p.Ser54Leu). One of the individuals was mosaic for the latter variant, while in all other cases the variant had occurred de novo.

Protein kinase A (PKA) is a tetrameric holoenzyme formed by the association of 2 catalytic (C) subunits with a regulatory (R) subunit dimer. Activation of PKA is achieved through binding of 2 cAMP molecules to each R-subunit, and unleashing(/dissociation) of C-subunits to engage substrates. PRKACA/B genes encode the Cα- and Cβ-subunits while the 4 functionally non-redundant regulatory subunits are encoded by PRKAR1A/1B/2A/2B genes.

The authors provide evidence that the variants confer increased sensitivity of PKA holoenzymes to activation by cAMP (compared to wt).

By performing ectopic expression of wt or mt PRKACA/B (variants studied : PRKACA p.Gly137Arg / PRKACB p.Gly235Arg) in NIH 3T3 fibroblasts, the authors demonstrate that inhibition of hedgehog signaling likely underlyies the developmental defects observed in affected individuals.

As for PRKACA, the authors cite another study where a 31-month old female with EvC syndrome diagnosis was found to harbor the aforementioned variant (NM_001304349.1:c.637G>A:p.Gly213Arg corresponding to NM_002730.4:c.409G>A / p.Gly137Arg) as a de novo event. Without additional evidence at the time, the variant was considered to be a candidate for this subject's phenotype (Monies et al 2019 – PMID: 31130284).

Gold et al (2020 - PMID: 33009664) report 5 individuals with CSNK1G1 variants, including updated information on a previously reported subject (Martin et al 2014 - PMID: 24463883).

Features included DD (5/5) with associated expressive language delay, ASD (in at least 3/5), seizures (2/5), dysmorphic facial features (4/5 arched eyebrows, 3/5 prominent central incisors, 2/5 epicanthus) and limb anomalies (2/5 - proximally placed thumb, 5th f. clinodactyly, asymmetric overgrowth - the other individual had tapering fingers). GI problems were observed in 4/5. Two individuals had macrocephaly and one had microcephaly. There was no formal developmental assessment although ID might be implied in at least 3 individuals (p1: 20y - single words/regression in walking following a seizure episode, p2: 8y - first words at 5y, assistance to feed, dress and bathe, ASD, p4: 13y - regression, assistance to feed and dress).

CSNK1G1 encodes the gamma-1 isoform of casein kinase 1, a protein involved in growth and cell morphogenesis. The gene has ubiquitous expression, incl. brain. As commented, in brain it regulates phosphorylation of NMDA receptors, playing a role in synaptic transmission (4 articles cited).

One individual had a 1.2 kb deletion spanning exon 3 of CSNK1G1 [chr15:64550952-64552120 - GRCh37]. Parental samples were unavailable for this individual. Four individuals were found to harbor de novo CSNK1G1 variants [NM_022048.3: c.688C>T - p.(Arg230Trp) dn | c.1255C>T - p.(Gln419*) dn | c.1214+5G>A dn with in silico predictions in favor of splice disruption | c.419C>T - p.(Thr140Met) dn].

Arg230Trp is however present once in gnomAD. The stopgain variant is located in the last exon and predicted to skip NMD.

There were no variant studies performed.

The Drosophila gish gene encodes a CK1γ homolog with preferential expression in the mushroom body. Heterozygous and homozygous mutants exhibit impairment in memory retention, more severe in homozygous flies. gish was also identified as a seizure modifier in a fly epilepsy model (heterozygous para mt flies).

Added comment: ITFG2 was suggested to be a candidate gene for autosomal recessive ID in the study by Harripaul et al (2018 - PMID: 28397838). The authors performed microarray and exome sequencing in 192 consanguineous families and identified a homozygous ITGF2 stopgain variant (NM_018463.3:c.472G>T / p.Glu158*) along with 3 additional variants segregating with ID within an investigated family (PK51). Cheema et al (2020 - https://doi.org/10.1038/s41525-020-00150-z) report briefly on a male, born to consanguineous parents presenting with NDD, seizures, regression and ataxia. There was a similarly affected female sibling. Evaluation of ROH revealed a homozygous ITFG2 nonsense variant [NM_018463.3:c.361C>T / p.(Gln121*)]. Families in this study were investigated by trio WES or WGS. Evaluation of data of the same lab revealed 3 additional unrelated subjects with overlapping phenotypes, notably NDD and ataxia. These individuals were - each - homozygous for pLoF variants [NM_018463.3:c.848-1G>A; NM_018463.3:c.704dupC, p.(Ala236fs), NM_018463.3:c.1000_1001delAT, p.(Ile334fs)]. As discussed in OMIM, ITFG2 encodes a subunit of the KICSTOR protein complex, having a role in regulating nutrient sensing by MTOR complex-1 (Wolfson et al 2017 - PMID : 28199306).

Rated Amber as Cheema et al report on diagnostic outcomes and multiple candidate genes as part of a heterogenous cohort and details are therefore limited.

Review for gene: SHMT2 was set to GREEN
Added comment: García‑Cazorla et al. (2020 - PMID: 33015733) report 5 individuals (from 4 families) with a novel brain and heart developmental syndrome caused by biallelic SHMT2 pathogenic variants.

All affected subjects presented similar phenotype incl. microcephaly at birth (5/5 with OFC < -2 SD though in 2/5 cases N OFC was observed later), DD and ID (1/5 mild-moderate, 1/5 moderate, 3/5 severe), motor dysfunction in the form of spastic (5/5) paraparesis, ataxia/dysmetria (3/4), intention tremor (in 3/?) and/or peripheral neuropathy (2 sibs). They exhibited corpus callosum hypoplasia (5/5) and perisylvian microgyria-like pattern (4/5). Cardiac problems were reported in all, with hypertrophic cardiomyopathy in 4/5 (from 3 families) and atrial-SD in the 5th individual (1/5). Common dysmorphic features incl. long palpebral/fissures, eversion of lateral third of lower eylids, arched eyebrows, long eyelashes, thin upper lip, short Vth finger, fetal pads, mild 2-3 toe syndactyly, proximally placed thumbs.

Biallelic variants were identified following exome sequencing in all (other investigations not mentioned). Identified variants were in all cases missense SNVs or in-frame del, which together with evidence from population databases and mouse model might suggest a hypomorphic effect of variants and intolerance/embryonic lethality for homozygous LoF ones.

SHMT2 encodes the mitohondrial form of serine hydroxymethyltransferase. The enzyme transfers one-carbon units from serine to tetrahydrofolate (THF) and generates glycine and 5,10,methylene-THF.

Mitochondrial defect was suggested by presence of ragged red fibers in myocardial biopsy of one patient. Quadriceps and myocardial biopsies of the same individual were overall suggestive of myopathic changes.

While plasma metabolites were within N range and SHMT2 protein levels not significantly altered in patient fibroblasts, the authors provide evidence for impaired enzymatic function eg. presence of the SHMT2 substrate (THF) in patient but not control (mitochondria-enriched) fibroblasts , decrease in glycine/serine ratios, impared folate metabolism. Patient fibroblasts displayed impaired oxidative capacity (reduced ATP levels in a medium without glucose, diminished oxygen consumption rates). Mitochondrial membrane potential and ROS levels were also suggestive of redox malfunction.

Shmt2 ko in mice was previously shown to be embryonically lethal attributed to severe mitochondrial respiration defects, although there was no observed brain metabolic defect.

The authors performed Shmt2 knockdown in motoneurons in Drosophila, demonstrating neuromuscular junction (# of satellite boutons) and motility defects (climbing distance/velocity).

He attained a few words and voluntary limb movements but never sat unsupported. He had pale optic discs and an axonal neuropathy. From 6 years of age, his condition began to deteriorate, with reduced motor abilities and alertness. An MRI of the brain showed atrophy of the superior cerebellar vermis and slimming of the posterior limb of the corpus callosum. VPS41 is component of the HOPS complex and other genes in the complex have been implicated in movement disorders.

Progressive generalization ensued, although most remained ambulant, and only a minority (16%) lost the ability to walk in adulthood. Additional clinical features of mild to moderate intellectual disability and neuropsychiatric symptoms were present in approximately one‐third. In 4 individuals, magnetic resonance imaging (MRI) showed bilateral and symmetrical hypointensity of the globi pallidi and sometimes also the midbrain and dentate nuclei, suggestive of iron deposition. Mild generalized cerebral atrophy was also apparent in 4 individuals.

Added comment: 2 unrelated patients with mild oculocutaneous albinism, moderate bleeding diathesis, platelet aggregation deficit, and a dramatically decreased number of platelet dense granules, all signs compatible with HPS. Identified distinct homozygous variants in the BLOC1S5 gene (patient 1: deletion of exons 3 and 4, patient 2: 1-bp deletion in exon 4). Parental segregation confirmatory in patient 1, quantitative PCR analysis confirmatory in patient 2). Functional tests performed on platelets of one patient displayed an absence of the obligate multisubunit complex BLOC-1, showing that the variant disrupts BLOC1S5 function and impairs BLOC-1 assembly. Expression of the patient-derived BLOC1S5 deletion in nonpigmented murine Bloc1s5-/- melan-mu melanocytes failed to rescue pigmentation, the assembly of a functional BLOC-1 complex, and melanosome cargo trafficking, unlike the wild-type allele. Pathogenic variants in the genes encoding three other BLOC-1 subunits (DTNBP1, BLOC1S3, and BLOC1S6) underlie HPS types 7, 8, and 9 respectively.

Mendeliome v0.4520 SLC12A2 Zornitza Stark edited their review of gene: SLC12A2: Added comment: Monoallelic :
DD/ID was a feature in >= 6 individuals with monoallelic de novo SLC12A2. An individual with an exon 22 truncating variant was reported to have normal milestones and cognitive function. Exon 21 variants have been described in individuals with rather isolated hearing impairment (possibly some associated motor delay, but normal cognition). Hearing impairment was also reported in 2/6 patients with variants in other exons (1 missense / 1 frameshift).

Biallelic :
DD/ID was reported in at least 3 individuals in literature. Hearing impairment has been reported on 2 occasions (although this was not probably evaluated in all subjects).

---

Monoallelic SLC12A2 mutations :

► Individuals with de novo mutations and developmental disorder were first identified by the DDD study (2017 - PMID: 28135719). 5 of them have been reported in detail by McNeill et al (below).

► McNeill et al (2020 - PMID: 32658972) report on 6 individuals with neurodevelopmental disorder due to de novo SLC12A2 mutation. All presented DD or ID ranging from mild to severe. ASD was reported in 3/6. Sensorineural hearing loss was a feature in 2/6 with the remaining having normal formal evaluations. Brain, cardiac and/or additional malformations were reported in a single individual. Following non-diagnostic prior work-up (CMA, FMR1 or other investigations) trio exome sequencing revealed missense (4/6) or truncating variants (2/6).

Three additional individuals (incl. a father and his son) with missense variants in exon 21 (NM_001046.3 / p.Glu979Lys and p.Glu980Lys) presented with bilateral sensorineural hearing loss. Speech and/or motor delay reported in these cases were attributed to the hearing impairment/vestibular arreflexia (cognitive abilities not tested).

SLC12A2 encodes sodium-potassium-chloride transporter 1 (also NKCC1).

The GTEx project has identified 8 isoforms. In brain both exon 21-containing/deleted isoforms are expressed (cited Morita et al 2014 - PMID: 24695712). As the authors discuss, RNA-seq of the developing mouse cochlea suggests that the exon 21 containing isoform is the single transcript expressed. Evidence from RNA-seq data (BrainSpan project) and literature suggests that the significant amounts of exon 21 lacking isoforms in fetal brain compensate for the deleterious effects of exon 21 variants and explain the lack of NDD in relevant patients.

Slc12a2 (NKCC1) null mouse model has demonstrated that the transporter plays a role in accumulation of the potassium rich endolymph in the inner ear, with NKCC1 absence causing sensorineural deafness and imbalance. Slc12a2 display cochlear malformations, loss of hair cells and hearing impairment (cited Delpire et al 1999 - PMID: 10369265). The brain phenotype has not been studied extensively, although loss of Slc12a2 has been shown to inhibit neurogenesis (cited: Magalhães and Rivera et al. - PMID: 27582690).

Slc12a2 null zebrafish display a collapse of the otic vesicle and reduced endolymph (Abbas and Whitfield, 2009 - PMID: 19633174) relevant to the human hearing disorder.

In vitro assessment of NKCC1 ion transporter function in Xenopus laevis, supported the deleterious effect of the identified variants (significant reduction in K+ influx). Using available single cell RNA-seq data the authors further demonstrated that SLC12A2 expressing cells display transcriptomic profiles reflective of active neurogenesis.

► Delpire et al (2016 - PMID: 27900370 - not reviewed in detail) described a 13 y.o. girl harboring a de novo 11-bp deletion in SLC12A2 exon 22. This individual reached developmental milestones on time and had a NORMAL cognitive function. Hearing was seemingly normal. Features included orthostatic intolerance, respiratory weakness, multiple endocrine abnormalities, pancreatic insufficiency and multiorgan failure incl. gut and bladder. Exome in the proband, parents and 3 unaffected sibs suggested SLC12A2 as the only candidate for her phenotype. Functional analyses in Xenopus laevis oocytes suggested that a non functional transporter was expressed and trafficked to the membrane as the wt. Detection of the truncated protein at higher molecular sizes suggested either enhanced dimerization or misfolded aggregate. There was no dominant-negative effect of mutant NKCC1. In patient fibroblasts a reduced total and NKCC1-mediated K+ influx.

► Mutai et al (2020 - PMID: 32294086) report on several individuals from 4 families, harboring variants within exon 21 or - in one case - at it's 3' splice-site (leading to skipping oe this exon at the mRNA level). All subjects were investigated for severe/profound hearing loss (in line with the role of exon 21-included isoforms in cochlea. The variant segregated with hearing impairment in 3 generations of a family while in all other subjects the variant had occured as de novo event. Despite motor delays (e.g. the subject from fam2 could not hold head or sit at the age of 10m / the proband in Fam3 was able to hold his head and walk at 6 and 20 m respectively) behavior and cognition were commented to be within normal range.

Biallelic SLC12A2 mutations:

► Anazi et al (2017 - PMID: 29288388) briefly reported on a 3 y.o. boy (17DG0776) with central hypotonia, neonatal respiratory distress, failure to thrive, global DD and microcephaly and a skeletal survey suggestive of osteopenia. After non-diagnostic prior investigations (CMA revealing a 1p duplication classified as VUS, extensive metabolic workup), WES revealed a homozygous SLC12A2 splicing variant [NM_001046.2:c.2617-2A>G].

► Macnamara et al (2019 - PMID: 30740830) described a 5.5 y.o. male with sensorineural hearing loss, profound delays in all developmental areas among several other features (choanal atresia, failure to thrive, respiratory problems, absent sweat and tear production or salivation, GI abnormalities). Genetic testing for several disorders considered (cystic fibrosis, spinal muscular atrophy, sequencing and del/dup analysis of mtDNA) was normal. CMA revealed paternal uniparental isodisomy for chr. 5 and WGS a homozygous 22kb deletion in SLC12A2. This was followed by confirmation of homozygosity in the proband, heterozygosity of the unaffected father, delineation of breakpoints (chr5:127441491-127471419). mRNA studies in patient fibroblasts confirmed deletion of ex2-7, splicing of ex1 directly to ex8 and introduction of a premature stop codon in ex9. qRT-PCR confirmed that mRNA is likely subjected to NMD (expression ~80% of control). Western blot confirmed absence of the protein in the patient's fibroblasts. Again mouse models are thought to recapitulate the hearing defect but also the deficient saliva production (cited Evans et al 2000 - PMID: 10831596). Again the authors speculate a role of SLC12A2 in brain development based on evidence from murine models (migration, dendritic growth, increse in neuron density through regulation of GABAergic signalling (Young et al 2012 - PMID: 23015452). Hypotheses are also made on a regulatory relationship between NKCC1 and CFTR based on mRNA data from the ko mouse model.

► Stödberg et al (2020 - PMID: 32754646) reported 2 sibs with a complex neurodevelopmental disorder due to compound heterozygosity for a frameshift SLC12A2 variant and a splicing one (NM_001046:c.1431delT and c.2006-1G>A). Both presented hypotonia, neonatal S. aureus parotitis and respiratory problems (incl. apneas). While the older sib died at the age of 22 days, the younger one had persistent respiratory issues incl. a dry respiratory mucosa motivating metabolic, immunology investigations and testing for CF. She displayed microcephaly (OFC -2.5 SD, H was also -3.5SD), severe intellectual disability. MRI was suggestive of white matter and basal ganglia abnormalities. Other features incl. hearing impairment, and lack of tears,saliva and sweat, constipation and intestinal malrotation. There was facial dysmorphism. The variants were the only retained following WGS of the 2 affected sisters, parents and an unaffected brother. The splicing variant was shown to result in skipping of exon 13, while the indel in NMD. Again the authors discuss that the deficient saliva production, impaired hearing and GI problems are recapitulated in the mouse model (several refs provided).; Changed rating: GREEN; Changed publications: 28135719, 32658972, 27900370, 32294086, 29288388, 30740830, 32754646; Changed phenotypes: Kilquist syndrome, deafness, intellectual disability, dysmorphic features, absent salivation, ectodermal dysplasia, constipation, intestinal malrotation, multiple congenital anomalies; Changed mode of inheritance: BOTH monoallelic and biallelic, autosomal or pseudoautosomal

Added comment: - PMID: 32181500 (2020) - Three patients from two independent consanguineous families with homozygous variants (c.3353G>A, p.Ser1118Asn and c.1289delA, p.His430Profs7*) in the FNIP1 gene. Both variants segregated with the disease phenotype in each family. Clinically, patients presented with combined immunodeficiency, cardiac findings (hypertrophic cardiomyopathy, Wolff‐Parkinson‐White syndrome), and myopathy of skeletal muscles with motor DD. Authors note phenotypic overlap with the murine model of FNIP1 deficiency, but no functional analyses of the variants or patient cells were performed.

- PMID: 32905580 (2020) - Three cases from unrelated families, all harbouring novel biallelic variants in FNIP1. Clinical manifestations in all patients include hypertrophic cardiomyopathy, severe and/or recurrent infections, absent circulating B-cells, and agammaglobulinemia; as well as either severe or intermittent neutropenia in two cases. Functional studies showed impairment of B-cell metabolism, including disruptions to mitochondrial numbers/activity and the PI3K/AKT pathway.

Mendeliome v0.4134 TRAPPC2L Arina Puzriakova changed review comment from: Gene is associated with Encephalopathy, progressive, early-onset, with episodic rhabdomyolysis in OMIM, but not in G2P.

PMID: 30120216 (2018) - Two unrelated probands with an identical homozygous missense (c.109G>T, p.Asp37Tyr) variant in TRAPPC2L. Both individuals presented neurodevelopmental delay, febrile illness-induced encephalopathy, and episodic rhabdomyolysis, followed by developmental arrest, seizures and tetraplegia. The variant segregated with the phenotype in each family, and haplotype analysis suggested a founder effect.

The mutant protein was expressed in patient fibroblasts, but displayed membrane trafficking delays. Studies in yeast showed that the variant impaired interaction with TRAPPC10, and increased levels of the active RAB11.


PMID: 32843486 (2020) - In an Ashkenazi Jewish family with three affected sibs with GDD/ID, WGS revealed a segregating homozygous missense variant (c.5G>C, p.Ala2Gly) in the TRAPPC2L gene. No seizures, brain MRI abnormalities, or illness provoked regression were documented in this family.

Comparable to the previous study, the variant resulted in delayed ER-to-Golgi trafficking and elevated levels of active RAB11. Studies using yeast and in vitro binding, showed that the variant disrupted interaction with another core TRAPP protein, TRAPPC6a.
Sources: Literature; to: Total of three families, but two share a founder variant, and there are some disparities between the clinical presentations reported in the two publications. Rating Amber as additional cases required to delineate the genotype-phenotype relationship.

The following head circumference measurements were provided for 6 of the affecteds:

51cm at 16yo; 50cm at 19yo; 42.5cm at 12mo, 45cm at 28mo, 45.2cm at 7yo; 45cm at 4yo.

3 of the families were consanguineous Saudi families with the same homozygous missense variant.

In vitro functional expression studies showed that both mutations caused impaired thioester binding with UFM1. Patient cells also showed decreased UFC1 intermediate formation with UFM1. The decrease in function was consistent with a hypomorphic allele, and the authors suggested that complete loss of function would be embryonic lethal.

PMID 30552426: 1 more individual with epileptic encephalopathy reported with a different homozygous missense variant in UFC1. The patient had microcephaly <3rd percentile.
