Shoichet et al. (2003) described a female patient with severe nonsyndromic mental retardation and a de novo balanced translocation t(X;7)(p11.3;q11.21) in whom they cloned the DNA fragment that contained the X chromosomal and the autosomal breakpoint. In silico sequence analysis demonstrated that the ZNF41 gene was disrupted. Expression studies indicated that ZNF41 transcripts were absent in the patient cell line, suggesting that the mental disorder in this patient resulted from loss of functional ZNF41. Screening of patients with mental retardation led to the identification of 2 other ZNF41 mutations that were not found in healthy control individuals. Based on their finding of the mutations in ZNF41 identified by Shoichet et al. (2003) in a total of 7 males in the NHLBI Exome Variant Server, and the additional finding of truncating ZNF41 variants in 1 male and 1 female in that database, Piton et al. (2013) classified the involvement of ZNF41 in mental retardation as highly questionable. Sources: Expert Review |

Mode of inheritance for gene: AGTR2 was set to X-LINKED: hemizygous mutation in males, biallelic mutations in females Phenotypes for gene: AGTR2 were set to X-linked complex neurodevelopmental disorder MONDO:0100148 Review for gene: AGTR2 was set to RED Added comment: Variants in AGTR2 have been reported in individuals presenting various neurodevelopmental phenotypes, including intellectual disability, autistic features, epileptic seizures, speech delay, restlessness, and hyperactivity, as early as 2002. Per criteria outlined by the ClinGen Lumping and Splitting Working Group, we found no difference in molecular mechanism, inheritance pattern, or phenotypic variability. Therefore, for the purposes of this curation, all of these features have been lumped into one disease entity, X-linked complex neurodevelopmental disorder. Although eight unique variants, including missense and truncating, have been reported in affected humans, the majority (six) have been ruled out from disease-causality based on high frequency in control populations (Piton et al., PMID 23871722), occurrence in unaffected males (Erdmann et al., PMID 14722754), non-segregation within a family (Bienvenu et al., PMID 12746399), and lack of enrichment in patients in a case-control study (Huang et al., PMID 16283672). Given that the two remaining variants are missense with no supporting functional evidence, and AGTR2 was the only gene sequenced in each case, the ClinGen Intellectual Disability and Autism Working Group recommended awarding 0 points for these variants. There are two AGTR2 mouse models which collectively show altered neuronal spine morphology, spatial memory impairment, delayed learning, and reduced exploratory behavior (PMIDs 18335189 and 7477267).

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.

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.

The ZFX variant was allelic with another X-linked variant in SHROOM4. These variants were inherited from the mother, who had random X inactivation pattern (PMID: 26740508). PMID: 38325380 reports 11 ZFX variants in 18 subjects from 16 unrelated families (14 males and 4 females) with an X-linked neurodevelopmental disorder with recurrent facial gestalt. Seven variants were truncating and the remaining were missense variants within the Zinc finger array. In the pedigree of family 6 (figure 3, PMID: 38325380), it was apparent that there were female carriers of the ZFX variant (GRCh38 chrX: 24229396A>G, c.2438A>G, p.Tyr774Cys) with hyperparathyroidism and two affected males and one affected female, with the neurodevelopmental disorder. It appeared that skewed X-inactivation in the female carriers was responsible for the different phenotypic features. The association between ZFX variants and a novel neurodevelopmental disorder, was further supported by functional studies showing altered transcriptional activity in missense variants and altered behavior in a zebrafish loss-of-function model.

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. Sources: Literature |

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.

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).

PMID:37054711 reported ten unrelated families with biallelic variants in INTS11 gene and they present with intellectual disability, global developmental and language delay, impaired motor development, and brain atrophy. Functional studies in Drosophila showed that dIntS11 (fly ortholog of INTS11) is essential and expressed in the central nervous systems in a subset of neurons and most glia in larval and adult stages. In addition, genes with two variants (p.Arg17Leu and p.His414Tyr) fail to rescue the lethality of null mutants in the Drosophila model, indicating that they are strong loss-of-function variants. The other five variants (p.Gly55Ser, p.Leu138Phe, p.Lys396Glu, p.Val517Met and p.Ile553Glu) rescue lethality but cause a shortened lifespan and bang sensitivity and affect locomotor activity, indicating that they are partial loss-of-function variants.

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.

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.

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. Sources: Literature |

During infancy/childhood profound gastrointestinal dysmotility, cerebrovascular disease, and multiple strokes. Described as a multisystemic smooth muscle dysfunction syndrome. Patient was found to have a de novo SNP in MIR145 NR_029686.1:n.18C>A. The MIR145transcript is processed into two microRNAs, with the variant position at nucleotide 3 of miR-145-5p. Transfection of an siRNA against mutant miR145-5p induced a notable decrease in the expression of several cytoskeletal proteins including transgelin, calponin, and importantly, smooth muscle actin. Hybridization analysis and miR RNA-seq demonstrated a decrease in expression of miR145-5p in the presence of mutant miR145-5p.

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. Sources: Literature |

Thbs1R1034C-mutant mice had elevated intraocular pressure (IOP), reduced ocular fluid outflow, and retinal ganglion cell loss. Histology revealed an abundant, abnormal extracellular accumulation of THBS1 with abnormal morphology of juxtacanalicular trabecular meshwork (TM), an ocular tissue critical for aqueous fluid outflow. Functional characterization showed that the THBS1 missense alleles found in affected individuals destabilized the THBS1 C-terminus, causing protein misfolding and extracellular aggregation. Analysis using a range of amino acid substitutions at position R1034 showed that the extent of aggregation was correlated with the change in protein-folding free energy caused by variations in amino acid structure.

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.

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. Sources: Literature |

Zornitza Stark edited their review of gene: PMM2: Added comment: Association with HIPKD: Cabezas et al (2017) reported co-occurrence of hyperinsulinaemic hypoglycaemia and polycystic kidney disease (HIPKD in 17 children from 11 unrelated families. Patients presented with hyperinsulinaemic hypoglycaemia in infancy and enlarged kidneys with multiple kidney cysts. Some progressed to ESKD and some had liver cysts. Whole-genome linkage analysis in 5 informative families identified a single significant locus on chromosome 16p13.2. Sequencing of the coding regions of all linked genes failed to identify biallelic mutations. Instead, they found in all patients a promoter mutation (c.-167G>T) in PMM2, either homozygous or in trans with PMM2 coding mutations. They found deglycosylation in cultured pancreatic β cells altered insulin secretion. In vitro, the PMM2 promoter mutation associated with decreased transcriptional activity in patient kidney cells and impaired binding of the transcription factor ZNF143. In silico analysis suggested an important role of ZNF143 for the formation of a chromatin loop including PMM2. They proposed that the PMM2 promoter mutation alters tissue-specific chromatin loop formation, with consequent organ-specific deficiency of PMM2 leading to the restricted phenotype of HIPKD. None of the patients exhibited the typical clinical or diagnostic features of CDG1A. Serum transferrin glycosylation was normal in 11 patients who had assessment.; Changed publications: 28108845, 28373276, 32595772; Changed phenotypes: Congenital disorder of glycosylation, type Ia (MIM#212065), Hyperinsulinaemic Hypoglycaemia and Polycystic Kidney Disease (HIPKD), MONDO:0020642, PMM2-related |

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.

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.

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. |

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.

| Mendeliome v0.12838 | CCR2 | Ain Roesley changed review comment from: Currently no mendelian gene-disease association; to: Vall64Ile has been associated with reduction in the progression to AIDS. Mutant results in normal expression levels of the CCR2 receptor and has no effect on the incidence of HIV infection. However, in contrast to normal CCR2 peptides, the mutant protein preferentially dimerizes with the CXCR4 polypeptide, isolating it in the endoplasmic reticulum. It is also thought that the inhibitory effect is dependent on the stages of HIV-1 infection and interactions with other genetic variants. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

| Mendeliome v0.12738 | PIGA | Zornitza Stark changed review comment from: PIGA 34875027: variants in PIGA causing a neurodevelopment disorder and a juvenile form of hereditary hemochromatosis reported in > three unrelated patients. All patients had increased serum iron, ferritin and transferrin saturation levels, high ALP and low hepcidin. All patients had generalised seizures and intellectual disability.

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. Sources: Literature |

Can cause hepatic dysfunction in infancy. Identification would prevent further investigation and potentially lead to optimising respiratory health due to adult onset respiratory involvement. MUTATIONAL & CLINICAL SPECTRUM ZZ genotype: 2% have severe, neonatal/early-onset liver disease (potentially fatal/requiring liver transplantation), up to 6% have childhood onset liver disease. Also associated with adult-onset lung disease particularly emphysema (50%+ penetrance) - smoking is an important risk factor (close to 100% penetrance). TREATMENT There is no specific treatment for liver disease beyond transplant. There is treatment (AAT augmentation therapy) available to delay progression of lung disease phenotype. |

Affected individuals in both families exhibited severe vocal fold paresis, a rare feature of peripheral nerve disease that can be life-threatening. Studies of mutant protein posttranslational modification and localization indicated that the mutations (p.Ser577Arg, p.Ser650Pro) impair protein glycosylation and reduce JAG1 cell surface expression. Mice harboring heterozygous CMT2-associated mutations exhibited mild peripheral neuropathy, and homozygous expression resulted in embryonic lethality by midgestation. Pre-existing rat model.

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. Sources: Expert Review |

| 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 | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

| Mendeliome v0.9776 | NEBL | Bryony Thompson Added comment: Comment on list classification: Limited gene-disease vailidity, Classification - 09/25/2020 by ClinGen Dilated Cardiomyopathy GCEP. Evidence Summary: NEBL was evaluated for autosomal dominant dilated cardiomyopathy (DCM). Human genetic evidence supporting this gene-disease relationship includes case-level data. Arimura and colleagues (2000, PMID: 11140941) analyzed 83 DCM patients and 311 healthy controls, identifying 4 missense variants of unknown significance (VUSs) in 4 DCM cases. High minor allele frequencies (MAFs) and lack of segregation excluded these variants as evidence. Purevjav and colleagues (2010, PMID: 20951326) investigated a total of 260 DCM patients and 300 unrelated ethnic matched controls by direct DNA sequencing. Authors identified 4 missense VUSs. One of these variants (Q128R) was downgraded in level of evidence due to the lack of segregation. The other 3 variants were not scored because of their MAF. Perrot and colleagues (2016, PMID: 27186169) investigated a total of 389 patients with DCM, HCM, or LVNC, 320 Caucasian sex-matched controls and 192 Caucasian sex-matched blood donors and identified 3 missense VUSs in 4 families. One of these variants was also carried by healthy relatives and therefore was excluded, however this may be explained by reduced penetrance. The 2 other variants lacked segregation as well and therefore were also excluded. In addition, this gene-disease association is supported by animal models. Mastronotaro and colleagues (2015, PMID: 25987543) created a NEBL knockout mice that exhibited normal cardiac function up to 9 months of age but after 2 weeks of transaortic constriction (TAC), these mice showed Z-line widening since the age of 5 months and upregulation of cardiac stress genes (basal and after TAC) However, absence of clinical DCM features in KO-NEBL mice as well as Western Blot analysis which contradicted previous findings by showing a similar protein expression between knockout and wild-type mice, excluding it as evidence. Purevjav and colleagues (2010, PMID: 20951326) generated a transgenic mouse overexpressing WT or mutant NEBL under the control of the α-MyHC promoter (4 variants were tested). Mice overexpressing p.K60N or p.Q128R variants died within 1 year because of severe heart enlargement and heart failure. Mice overexpressing p.G202R or p.A592E were born and developed normally but after 6 months displayed reduced stress tolerance, cardiac enlargement due to left ventricle dilation, myocyte disarray, and interstitial cell infiltration. In summary, there is limited evidence to support this gene-disease relationship. More evidence is needed to support the relationship of NEBL and autosomal dominant DCM. This classification was approved by the ClinGen Dilated Cardiomyopathy Working Group on October 11, 2019 (SOP Version 7).

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). Sources: Expert Review |

| 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. PMID: 26506440 - speculates low penetrance for PTCs in this gene. Acknowledges variants in ExAC, describes them as benign Note no P/LP variants in ClinVar |

(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.

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. |

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.

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. Sources: Literature |

Sources: Literature Mode of inheritance for gene: VPS50 was set to BIALLELIC, autosomal or pseudoautosomal Publications for gene: VPS50 were set to 34037727 Phenotypes for gene: VPS50 were set to Neonatal cholestatic liver disease; Failure to thrive; Profound global developmental delay; Postnatal microcephaly; Seizures; Abnormality of the corpus callosum 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.

(2016) identified a heterozygous deletion/insertion mutation in the amelotin gene that segregated with the phenotype in the family. The mutation was predicted to result in an in-frame deletion of 92 amino acids, shortening the protein from 209 to 117 amino acids. Mode of pathogenicity not established. Toxic gain of function proposed as Atmn KO and +/- mice did not recapitulate the human phenotype. Sources: Expert Review |

Biallelic PIDD1 pathogenic variants have been reported in 26 individuals (11 families) with DD (all), variable degrees of ID (mild to severe), behavioral (eg. aggression/self-mutilation in several, ADHD) and/or psychiatric abnormalities (ASD, psychosis in 5 belonging to 3 families), well-controlled epilepsy is some (9 subjects from 6 families) and MRI abnormalities notably abnormal gyration pattern (pachygyria with predominant anterior gradient) as well as corpus callosum anomalies (commonly thinning) in several. Dysmorphic features have been reported in almost all, although there has been no specific feature suggested. The first reports on the phenotype associated with biallelic PIDD1 mutations were made by Harripaul et al (2018 - PMID: 28397838) and Hu et al (2019 - PMID: 29302074) [both studies investigating large cohorts of individuals with ID from consanguineous families]. Sheikh et al (2021 - PMID: 33414379) provided details on the phenotype of 15 individuals from 5 families including those from the previous 2 reports and studied provided evidence on the role of PIDD1 and the effect of variants. Zaki et al (2021 - PMID: 34163010) reported 11 additional individuals from 6 consanguineous families, summarize the features of all subjects published in the literature and review the neuroradiological features of the disorder. PIDD1 encodes p53-induced death domain protein 1. The protein is part of the PIDDosome, a multiprotein complex also composed of the bipartite linker protein CRADD (also known as RAIDD) and the proform of caspase-2 and induces apoptosis in response to DNA damage. There are 5 potential PIDD1 mRNA transcript variants with NM_145886.4 corresponding to the longest. Similar to the protein encoded by CRADD, PIDD1 contains a death domain (DD - aa 774-893). Constitutive post-translational processing gives PIDD1-N, PIDD1-C the latter further processed into PIDD1-CC (by auto-cleavage). Serine residues at pos. 446 and 588 are involved in this autoprocessing generating PIDD1-C (aa 446-910) and PIDD1-CC (aa 774-893). The latter is needed for caspase-2 activation. Most (if not all) individuals belonged to consanguineous families of different origins and harbored pLoF or missense variants. Variants reported so far include : c.2587C>T; p.Gln863* / c.1909C>T ; p.Arg637* / c.2443C>T / p.Arg815Trp / c.2275-1G>A which upon trap assay was shown to lead to skipping of ex15 with direct splicing form exon14 to the terminal exon 16 (resulting to p.Arg759Glyfs*1 with exlcusion of the entire DD) / c.2584C>T; p.Arg862Trp / c.1340G>A; p.Trp447* / c.2116_2120del; p.Val706His*, c.1564_1565del; p.Gly602fs*26 Evidence so far provided includes: - Biallelic CRADD variants cause a NDD disorder and a highly similar gyration pattern. - Confirmation of splicing effect (eg. for c.2275-1G>A premature stop in position 760) or poor expression (NM_145886.3:c.2587C>T; p.Gln863*). Arg815Trp did not affect autoprocessing or protein stability. - Abnormal localization pattern, loss of interaction with CRADD and failure to activate caspase-2 (MDM2 cleavage assay) [p.Gln863* and Arg815Trp] - Available expression data from GTEx (PIDD1 having broad expression in multiple tissues, but higher in brain cerebellum) as well as BrainSpan and PsychEncode studies suggesting high coexpression of PIDD1, CRADD and CASP2 in many regions in the developing human brain. - Variants in other genes encoding proteins interacting with PIDD1 (MADD, FADD, DNAJ, etc) are associated with NDD. Pidd-1 ko mice (ex3-15 removal) lack however CNS-related phenotypes. These show decreased anxiety but no motor anomalies. This has also been the case with Cradd-/- mice displaying no significant CNS phenotypes without lamination defects. There is currently no associated phenotype in OMIM. PIDD1 is listed in the DD panel of G2P (PIDD1-related NDD / biallelic / loss of function / probable) . SysID includes PIDD1 among the current primary ID genes. Sources: Expert Review |

Affected individuals had mandibular hypoplasia, microtia, facial and preauricular tags, epibulbar dermoids, lateral oral clefts in addition to skeletal and cardiac abnormalities. Targeted morpholino knockdown of SF3B2 in Xenopus resulted in disruption of cranial neural crest precursor formation and subsequent craniofacial cartilage defects, supporting a link between spliceosome mutations and impaired neural crest development in congenital craniofacial disease. The families were ascertained from a cohort and the authors suggest that haploinsufficient variants in SF3B2 are the most prevalent genetic cause of CFM, explaining ~3% of sporadic and ~25% of familial cases.

All missense variants were confirmed to be de novo in eight individuals for whom parental data was available. The 11 individuals in the cohort share clinical features of variable severity. All 11 have GDD or ID and dysmorphic features, and a majority has mood or behavioural disorders and structural brain abnormalities: - Structural brain abnormalities on MRI (9/11) included partial or full agenesis of the corpus callosum (6/9), disorganized cerebellar folia (4/9), delayed myelination (3/9), decreased white matter volume (3/9), pons hypoplasia (3/9), and dysmorphic dentate nuclei (3/9). Six of those with brain abnormalities also presented with seizures. - Nine have abnormal vision, including strabismus in four and inability to fix or follow in the two with homozygous loss-of-function variants. - Hypotonia ranging from mild to severe was reported in 7 of the 11 individuals. - Six have mood or behavioural disorders, particularly anxiety (3/6). - Consistent dysmorphic facial features included microcephaly, prominent forehead, hypertelorism, down-slanting palpebral fissures, full cheeks, and micrognathia. The severity of disease in the two siblings with homozygous disruption of ClC-3 is consistent with the drastic phenotype seen in Clcn3 KO mice. The disease was more severe in two siblings carrying homozygous loss-of-function variants with the presence of GDD, absent speech, seizures, and salt and pepper fundal pigmentation in both individuals, with one deceased at 14 months of age. The siblings also had significant neuroanatomical findings including diffusely decreased white matter volume, thin corpora callosa, small hippocampi, and disorganized cerebellar folia. Supporting biallelic inheritance for LoF variants, disruption of mouse Clcn3 results in drastic neurodegeneration with loss of the hippocampus a few months after birth and early retinal degeneration. Clcn3−/− mice display severe neurodegeneration, whereas heterozygous Clcn3+/− mice appear normal. Patch-clamp studies were used to investigate four of the missense variants. These suggested a gain of function in two variants with increased current in HEK cells, however they also showed reduced rectification of voltage and a loss of transient current, plus decreased current amplitude, glycosylation and surface expression when expressed in oocytes, and were suspected to interfere with channel gating and a negative feedback mechanism. These effects were also shown to vary depending on pH levels. The current of the remaining two variants did not differ from WT. For heterozygous missense variants, the disruption induced may be at least partially conferred to mutant/WT homodimers and mutant/ClC-4 heterodimers. Both loss and gain of function in this gene resulted in the same phenotype. Sources: Literature |

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).

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*).

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.

"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." |

Early-onset PD reported with mono-allelic variants.; to: Well established gene-disease association for bi-allelic variants. Early-onset PD reported with mono-allelic variants. The PSAP gene encodes saposins A, B, C and D. Variants resulting in PSAP null allele can be shared in patients with the deficit of other saposins (A-D) or whole prosaposin. The patient's phenotype depends then on the nature of the second allele - atypical Gaucher disease in case of saposin A, MLD in case of saposin B, and Krabbe disease in case of saposin C impairing mutations. The clinically most severe prosaposin deficit is caused by the presence of two PSAP null alleles. |

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. Sources: Literature |

PMID 30445423 reviews 34 patients from 26 families: 13 different variants in SPINT2 were seen, including 3 premature termination codons, 2 start codon removals, and 3 canonical splice site variants, supporting loss of function as the pathogenic mechanism. The most commonly observed variant was Y163C, observed in 40 (59%) of 68 disease alleles. Seven unrelated patients with the Y163C mutation had a shared haplotype, suggesting that it is a founder mutation. Choanal atresia (20/34) and keratitis of infantile onset (26/34) were the most common findings. All patients presented with intractable diarrhoea, with onset typically in the first 2 weeks of life. Episodes of intestinal pseudoobstruction sometimes preceded the onset of diarrhoea. Characteristic epithelial tufts on intestinal histology were seen in 13 of the 34 patients. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Authors state that not all features of the individual could be explained by the RPS6KA3 variant, and that consideration of Coffin-Lowry sysndrome was only made after identification of the RPS6KA3 variant. Therefore individual has there is a blended phenotype of Coffin–Lowry syndrome and Sjögren–Larsson syndrome. From functional studies authors propose that the ALDH1L2 loss induces mitochondrial dysfunction due to reduced NADPH and increased oxidative stress (PMID: 31341639). Knockout mouse model was viable and did not show an apparent phenotype, however metabolomic analysis showed vastly changed metabotypes in the liver and plasma in these mice suggesting channeling of fatty acids away from β-oxidation. Authors therefore postulate that the role of ALDH1L2 in the lipid metabolism explains why the loss of this enzyme is associated with neuro-cutaneous disease. Sources: Literature |

Both variants identified are predicted to result in truncated proteins losing the capacity of binding to ubiquitinated proteins, hence appearing to exhibit a dominant‐negative effect on the normal function of the endosome‐specific endosomal sorting complexes required for the transport‐I complex.

The lesions are progressive, becoming thicker with verrucous fissures on the palms and soles over time. In addition, affected individuals exhibit perioral hyperkeratosis, and may have lesions around other orifices as well, such as the nostrils, perineum, and anus. Most patients also have hyperkeratotic nails and light-colored woolly hair. Two families reported with bi-allelic variants and Erythrokeratodermia variabilis et progressiva-7 (EKVP7), which is characterised by palmoplantar keratoderma that extends to the dorsal surface of the hands and feet (transgrediens), as well as erythematous annular skin lesions.

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.

The variants were located in the N-terminal domain of the A isoform of FGF13/FHF2 (FHF2A). The X-linked FHF2 gene (also known as FGF13) has alternative first exons which produce multiple protein isoforms that differ in their N-terminal sequence. The variants were located at highly conserved residues in the FHF2A inactivation particle that competes with the intrinsic fast inactivation mechanism of Nav channels. Functional characterization of mutant FHF2A co-expressed with wild-type Nav1.6 (SCN8A) revealed that mutant FHF2A proteins lost the ability to induce rapid-onset, long-term blockade of the channel while retaining pro-excitatory properties. These gain-of-function effects are likely to increase neuronal excitability consistent with the epileptic potential of FHF2 variants. Sources: Literature |

All presented with almost complete absence of motor and cognitive development, progressive or congenital microcephaly, spastic tetraplegia or dystonia, and vision impairments. For most, the first symptoms included neonatal severe axial hypotonia and epilepsy that started during the first months or years of life. Prenatal symptoms of microcephaly associated with increased thalami echogenicity were detected in one, while the seven other individuals presented with progressive microcephaly. Some exhibited rapidly progressive phenotype and the affected children died in their infancy or middle-childhood. Strikingly, all the affected children had a unique brain MRI showing a mild to severe PCH, fluid-filled posterior fossa, with dilated lateral ventricles. In addition, severe atrophy at the level of the basal ganglia or thalami often associated with typical T2 hypersignal were identified in all the patients MRI. Supportive functional data showing accumulation of highly phosphorylated inositols, mostly inositol hexakisphosphate (IP6), detected in HEK293 cells, fibroblasts, iPSCs and differentiating neurons lacking MINPP1. In mutant cells, higher IP6 level is expected to be associated with an increased chelation of intracellular cations, such as iron or calcium, resulting in decreased levels of available ions.

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). Sources: Literature |

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). Sources: Literature |

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).

| 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 |

Affected individuals from 7 families presented with CAKUT while all of them displayed extra-renal features. Neurological manifestations were reported in 16 individuals from 14 families (data not available for 1 fam), among others hypotonia (3/14 fam), speech delay (4/14 fam), global DD (9/14 fam), ID (4/14 fam), microcephaly (4/14 fam). ASD was reported in 4 fam (4 indiv). Seizures were reported in 2 fam (2 indiv). Variable other features included cardiac defects, facial dysmorphisms, small hands and feet with dys-/hypo-plastic nails and clinodactyly. 14 pLoF variants were identified, in most cases as de novo events (8 fam). In 2 families the variant was inherited from an affected parent. Germline mosaicism occurred in 1 family. The human disease features were recapitulated in a X. tropicalis morpholino knockdown, with expression of truncating variants failing to rescue renal and craniofacial defects. Heterozygous Zmym2-deficient mice also recapitulated the features of CAKUT. ZMYM2 (previously ZNF198) encodes a nuclear zinc finger protein localizing to the nucleus (and PML nuclear body). It has previously been identified as transcriptional corepressor interacting with nuclear receptors and the LSD1-CoREST-HDAC1 complex. It has also been shown to interact with FOXP transcription factors. The authors provide evidence for loss of interaction of the truncated ZMYM2 with FOXP1 (mutations in the latter having recently been reported in syndromic CAKUT). Sources: Literature |

Zornitza Stark changed review comment from: 5 unrelated families with homozygous mutations in SVBP. The mutations segregated with the disorder in all families. In vitro functional cellular expression studies showed that protein levels of the SVBP mutants were barely detectable, suggesting instability, and that the mutant proteins had lost VASH/SVBP catalytic detyrosination activity toward tubulin. Knockdown of about 50% Svbp expression using shRNA in rat hippocampal neurons impaired the formation of excitatory synapses compared to controls.

The current review is based only on this reference. The authors provide clinical details on 6 affected individuals from 5 families. Features included postnatal growth delay, DD and ID (6/6 - also evident for those without formal IQ assesment), seizures (3/6 from 2 families), prominent forehead with presence of other facial features and variable head circumference (5th to >97th %le), ocular anomalies (5/6 - strabismus/nystagmus/Axenfeld-Rieger), cardiac (3/6 - ASD/Fallot) and genitourinary anomalies (3/6). In the first of these families (Armfield et al 1999 - PMID: 10398235), linkage analysis followed by additional studies (Sanger, NGS of 718 genes on chrX, X-exome NGS - several refs provided) allowed the identification of a FAM50A variant. Variants in other families were identified by singleton (1 fam) or trio-ES (3 fam). In affected individuals from 3 families, the variant had occurred de novo. Carrier females in the other families were unaffected (based on pedigrees and/or the original publication). XCI was rather biased in most obligate carrier females from the 1st family (although this ranged from 95:5 to 60:40). Missense variants were reported in all affected subjects incl. Trp206Gly, Asp255Gly, Asp255Asn (dn), Glu254Gly (dn), Arg273Trp (dn) (NM_004699.3). Previous studies have demonstrated that FAM50A has ubiquitous expression in human fetal and adult tissues (incl. brain in fetal ones). Immunostaining suggests a nuclear localization for the protein (NIH/3T3 cells). Comparison of protein levels in LCLs from affected males and controls did not demonstrate significant differences. Protein localization for 3 variants (transfection of COS-7 cells) was shown to be similar to wt. Complementation studies in zebrafish provided evidence that the identified variants confer partial loss of function (rescue of the morpholino phenotype with co-injection of wt but not mt mRNA). The zebrafish ko model seemed to recapitulate the abnormal development of cephalic structures and was indicative of diminished/defective neurogenesis. Transcriptional dysregulation was demonstrated in zebrafish (altered levels and mis-splicing). Upregulation of spliceosome effectors was demonstrated in ko zebrafish. Similarly, mRNA expression and splicing defects were demonstrated in LCLs from affected individuals. FAM50A pulldown followed by mass spectrometry in transfected HEK293T cells demonstrated enrichment of binding proteins involved in RNA processing and co-immunoprecipitation assays (transfected U-87 cells) suggested that FAM50A interacts with spliceosome U5 and C-complex proteins. Overall aberrant spliceosome C-complex function is suggested as the underlying pathogenetic mechanism. Several other neurodevelopmental syndromes are caused by variants in genes encoding C-complex affiliated proteins (incl. EFTUD2, EIF4A3, THOC2, etc.). Sources: Literature |

Melanie Marty changed review comment from: A recurring homozygous missense variant p.Asp211Gly has been identified in at least 64 cases of hydrolethalus syndrome, described as a Finnish founder mutation (PMID: 15843405, PMID: 18648327). Functional studies in human and patient cells have shown mislocalisation of the protein to the nucleus (PMID: 15843405, PMID: 19400947). Functional studies in c. elegans showed that this variant impaired ciliogenesis (PMID: 19656802). Functional studies in drosophila showed that deletion of HYLS1 led to cilia dysfunction (PMID: 32509774). 2 homozygous living siblings (stop-loss, extension variant p.Ter300TyrextTer11) both diagnosed with Joubert syndrome. Patients had molar tooth signs and dysplasia of cerebellar vermis (PMID: 26830932).

| Mendeliome v0.3675 | PIGQ |
Zornitza Stark edited their review of gene: PIGQ: Added comment: Homozygous or compound heterozygous mutations in PIGQ cause Epileptic encephalopathy, early infantile, 77 (MIM #618548). Johnstone et al (2020 - PMID: 32588908) describe the phenotype of 7 children (from 6 families) with biallelic PIGQ pathogenic variants. The authors also review the phenotype of 3 subjects previously reported in the literature (by Martin et al, Alazami et al, Starr et al - respective PMIDs: 24463883, 25558065, 31148362). Affected individuals displayed severe to profound global DD/ID and seizures with onset in the first year of life. There were variable other features incl. - among others - genitourinary, cardiac, skeletal, ophthalmological anomalies, gastrointestinal issues. Within the cohort there was significant morbidity/mortality. PIGQ encodes phosphatidylinositol glycan anchor biosynthesis class Q protein, playing a role (early) in the biosynthesis of the GPI-anchor. Several genes in the GPI biosynthesis pathway cause multi-system disease with DD/ID and seizures. Flow cytometry has been used in individuals with PIGQ-related disorder. Serum ALP was elevated in some (4) although - as the authors comment - elevations are more typical in disorders affecting later steps of GPI biosynthesis. More than 10 variants have been reported to date (missense / pLoF).; Changed phenotypes: Epileptic encephalopathy, early infantile, 77, MIM# 618548 |

In total 32 individuals from 21 families are reported, with biallelic variants identified in individuals from 13 families and de novo in 8 families. Similar features were reported for AR/AD occurrences of the disorder and included microcephaly (90% - most often primary), epilepsy (23/32 or 74% - variable semiology incl. partial/myoclonic/generalized tonic-clonic seizures), DD and ID (as a universal feature), abnormal tone in several (hypotonia/spasticity), ataxia, demyelinating peripheral neuropathy (in 3 or more for each inheritance mode - or a total of 25%). Some individuals had dysmorphic features. NARS1 encodes an aminoacyl-tRNA synthetase (ARS) [asparaginyl-tRNA synthetase 1]. Aminoacyl-tRNA synthetases constitute a family of enzymes catalyzing attachment of amino-acids to their cognate tRNAs. As the authors comment, mutations in genes encoding several other ARSs result in neurological disorders ranging from peripheral neuropathy to severe multi-systemic NDD. Dominant, recessive or both modes for inheritance for mutations in the same gene (e.g. AARS1, YARS1, MARS1, etc) have been reported. Some variants were recurrent, e.g. the c.1600C>T / p.Arg534* which occurred in 6 families as a de novo event or c.1633C>T p.Arg545Cys (homozygous in 6 families). 3 different variants were reported to have occured de novo (c.965G>T - p.Arg322Leu, c.1525G>A - p.Gly509Ser, p.Arg534*) with several other variants identified in hmz/compound htz individuals. A single SNV (c.1067A>C - p.Asp356Ala) was suggested to be acting as modifier and pathogenic only when in trans with a severe variant. [NM_004539.4 used as RefSeq for all]. The authors provide several lines of evidence for a partial loss-of-function effect (e.g. reduction in mRNA expression, enzyme levels and activity in fibroblasts or iNPCs) underlying pathogenicity of the variants identified in individuals with biallelic variants. A gain-of-function (dominant-negative) effect is proposed for de novo variants (such effect also demonstrated for the p.Arg534* in a zebrafish model). Sources: Literature |

Zornitza Stark Added comment: Comment when marking as ready: Lenz et al (2020 - PMID: 32699352) review the phenotype of 25 affected individuals from 15 families. Seizures occurred in 19/24 and were commonly associated with infections. Encephalopathic episodes (in 13 patients) accompanied by seizures up to status epilepticus occurred independently of hepatic decompensation. In addition 22/24 presented with neurodevelopmental delay. The authors comment that cognitive impairment was present in 13/17 individuals (mild-severe) whereas most presented with learning disabilities. These patients will most likely investigated for their liver disease (although presentation was highly variable and/or very mild in few). The gene encodes a cytoplasmic amino-acyl tRNA synthetase (ARS) with neurologic manifestations observed in almost all patients (and seizures / DD and ID common to other disorders due to mutations in other genes encoding for ARSs). Please note that the HGNC approved symbol for this gene is LARS1. |

Clinical presentation included DD, ID (severe in 2 subjects from fam1, borderline intellectual functioning in fam2), dysmorphic features and brain abnormalities. Cerebellar anomalies were common to all with a molar tooth sign observed in one (1/3). Other findings limited to subjects from one family included acquired microcephaly, congenital contractures, spastic quadriplegia (each observed 2/3). Previous investigations were in all cases non-diagnostic. WES identified biallelic EXOC2 mutations in all affected individuals. EXOC2 encodes an exocyst subunit. The latter is an octameric complex, component of the membrane transport machinery, required for tethering and fusion of vesicles at the plasma membrane. As discussed ,vesicle transport is important for the development of brain and the function of neurons and glia. Exocyst function is also important for delivery of Arl13b to the primary cilium (biallelic ARL13B mutations cause Joubert syndrome 8) and ciliogenesis. Affected subjects from a broader consanguineous family (fam1) were homozygous for a truncating variant. Fibroblast studies revealed mRNA levels compatible with NMD (further restored in presence of CHX) as well as reduced protein levels. The female belonging to the second non-consanguineous family was found to harbor 2 missense variants in trans configuration. An exocytosis defect was demonstrated in fibroblasts from individuals belonging to both families. Ciliogenesis appeared to be normal, however Arl13b localization/recruitment to the cilia was reduced compared with control cells with the defect rescued upon exogenous expression of wt EXOC2. Mutations in other genes encoding components of the exocyst complex have been previously reported in individuals with relevant phenotypes (e.g. EXOC8 in a boy with features of Joubert s. or EXOC4 in nephrotic syndrome). The authors discuss on the essential role of EXOC2 based on model organism studies (e.g. impaired neuronal membrane traffic, failure of neuronal polarization and neuromuscular junction expansion seen in Drosophila Sec5 (EXOC2) null mutants).

Only a single study reported screening human cases. In a screen of 104 probands with KS or nIHH, four heterozygous AXL mutations were identified in two KS and two nIHH unrelated subjects (two males and two females). Three of the variants appear to be too common in gnomAD v2.1 given the reported prevalence of KS reported in GeneReviews (1:30,000 in males and 1:125,000 in females): c.587-6C>T (normal splicing in RNA studies, NFE AF 0.0001472), p.Q361P (NFE 0.002560), p.L50F (AJ 0.004405). The other variant p.S202C (4 hets, 1 female in gnomAD v2.1) is rare enough in gnomAD for a dominant disorder. In vitro functional assays were conducted and p.S202C had an significant effect on function, but so did the more common variant p.Q361P. Sources: Literature |

Animal knockout functional studies supported gene-disease association. PMID: 30573563 "By analysing WES data based on allele frequencies of in-house controls, population allele frequencies and in silico prediction tools, two rare homozygous mutations in USP45 were identified in two unrelated families. Immunohistochemistry of USP45 in the human and zebrafish retinal sections revealed enriched expression in the inner segments of photoreceptors. The knockdown of usp45 transcript in zebrafish led to abnormal retinal development with effects on photoreceptors, which could be successfully rescued by wild-type usp45 mRNA. Moreover, targeted knockout of Usp45 in mice caused abnormal electroretinography responses, similar to that seen in patients with LCA." Sources: Literature |

Elena Savva edited their review of gene: KCNJ11: Added comment: Congenital hyperinsulinism (HI) variants are generally reported in heterozygous patients where they also carry a somatic 2nd hit, or have isodisomy of the paternal allele (focal HI), or in bilallelic patients (diffuse HI). This condition can be dominant (but rarely), where patients with these missense are diazoxide-responsive. Patients with recessively inherited variants are diazoxide-unresponsive (OMIM, PMID:11395395, PMID: 23275527, PMID: 23345197). Genotype-phenotype correlation: Permanent neonatal diabetes – GOF (OMIM) Permanent neonatal diabetes + other features – GOF (OMIM) Congenital hyperinsulinism – LOF (PMID:18250167).

Patient cell extracts showed absence of the full-length TDP2 protein and absence of 5-prime TDP activity, consistent with a loss of function, although 3-prime TDP activity, conferred by TDP1, was normal. In addition, patient lymphoblastoid cells were hypersensitive to the TOP2 poison etoposide. The findings indicated impaired capacity for double-strand break repair. 1 unrelated Egyptian patient with a similar disorder was homozygous for a truncating mutation in the TDP2 gene 1 unrelated Caucasian patient with same homozygous splice site mutation in the TDP2 gene. Western blot analysis did not detect TDP2 protein in patient primary skin fibroblasts. Patient fibroblasts showed an inability to rapidly repair topoisomerase-induced DNA double-strand breaks in the nucleus and also showed a profound hypersensitivity to this type of DNA damage. Complementation of patient cells with recombinant human TDP2 restored normal rates of nuclear DSB repair. Sources: Expert list |

The mutation segregated with the disorder in the family. In vitro functional expression studies in CHO cells (AP-1 cells) showed that the mutation caused decreased levels of protein expression and reduced oligosaccharide maturation/glycosylation compared to wildtype, indicating impaired posttranslational processing. Subcellular localization studies indicated that protein trafficking was unaffected by the mutation. However, examination of the trans-Golgi compartment suggested a gain-of-function effect and a perturbation of glycosylation of secretory cargo. Serum transferrin studies in 1 patient suggested a glycosylation defect. Sources: Literature |

Sources: Literature Mode of inheritance for gene: PIGB was set to BIALLELIC, autosomal or pseudoautosomal Publications for gene: PIGB were set to 31256876 Phenotypes for gene: PIGB were set to Epileptic encephalopathy, early infantile, 80; OMIM #618580 Review for gene: PIGB was set to GREEN Added comment: 10 unrelated families with biallelic mutations in PIGB, with global DD and/or ID, and seizures. Two had polymicrogyria, 4 had a peripheral neuropathy, and 2 had a clinical diagnosis of DOORS syndrome. Patient lymphocytes and fibroblasts showed variably decreased levels of cell surface GPI-anchored proteins, including CD16 and CD59. In vitro functional expression studies performed with some of the mutations in PIGB-null CHO cells showed that the mutant proteins were unable to fully restore expression of GPI-anchored surface proteins, consistent with a loss of function, although the mutations had variable effects.

Sources: Literature Mode of inheritance for gene: PAK1 was set to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted Publications for gene: PAK1 were set to 31504246; 30290153 Phenotypes for gene: PAK1 were set to Intellectual developmental disorder with macrocephaly, seizures, and speech delay; OMIM #618158 Review for gene: PAK1 was set to GREEN Added comment: 2 unrelated individuals with de novo PAK1 mutations, with developmental delay, secondary macrocephaly, seizures, and ataxic gait. Enhanced phosphorylation of the PAK1 targets JNK and AKT shown in fibroblasts of one subject and of c-JUN in those of both subjects compared with control subjects. In fibroblasts of the 2 affected individuals, they observed a trend toward enhanced PAK1 kinase activity. By using co-immunoprecipitation and size-exclusion chromatography, they observed a significantly reduced dimerization for both PAK1 mutants compared with wild-type PAK1. 4 unrelated individuals with intellectual disability, macrocephaly and seizures, with de novo heterozygous missense variants in PAK1.

Zornitza Stark gene: GRIA2 was added gene: GRIA2 was added to Mendeliome_VCGS. Sources: Literature Mode of inheritance for gene: GRIA2 was set to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted Publications for gene: GRIA2 were set to 31300657 Phenotypes for gene: GRIA2 were set to Intellectual disability; autism; Rett-like features; epileptic encephalopathy Review for gene: GRIA2 was set to GREEN Added comment: 28 unrelated patients with ID, ASD, Rett-like features, seizures/EE, and de novo heterozygous GRIA2 mutations. In functional expression studies, mutations led to a decrease in agonist-evoked current mediated by mutant subunits compared to wild-type channels. When GluA2 subunits are co-expressed with GluA1, most GRIA2 mutations cause a decreased current amplitude and some also affect voltage rectification. Sources: Literature |

In vitro functional expression studies in HEK293 cells showed that the mutant subunit was expressed at the surface and incorporated into the channel, but the mutant channel was 10 times more sensitive to GABA compared to wildtype. This increased sensitization resulted in increased receptor desensitization to GABA, with a reduced maximal GABA-evoked current and impaired capacity to pass GABAergic chloride current.
