| Mendeliome v1.956 | RAB34 |
Sarah Pantaleo gene: RAB34 was added gene: RAB34 was added to Mendeliome. Sources: Literature Mode of inheritance for gene: RAB34 was set to BIALLELIC, autosomal or pseudoautosomal Publications for gene: RAB34 were set to PMID: 37384395 Phenotypes for gene: RAB34 were set to Clefting; corpus callosum; short bones; hypertelorism; polydactyly; cardiac defects; anorectal anomalies Penetrance for gene: RAB34 were set to Complete Review for gene: RAB34 was set to GREEN Added comment: Oral-facial-digital syndromes (OFDS) are a group of clinically and genetically heterogenous disorders characterised by defects in the development of the face and oral cavity along with digit anomalies. Pathogenic variants in >20 genes encoding ciliary proteins have been found to cause OFDS. Identified by WES biallelic missense variants in a novel disease-causing ciliary gene RAB34 in four individuals from three unrelated families (aided by GeneMatcher). Affected individuals presented a novel form of OFDS accompanied by cardiac, cerebral, skeletal (eg. Shortening of long bones), and anorectal defects. RAB34 encodes a member of the Lab GTPase superfamily and was recently identified as a key mediator of ciliary membrane formation. Protein products of pathogenic variants clustered near the RAB34 C-terminus exhibit a strong loss of function. Onset is prenatal (multiple developmental defects including short femur, polydactyly, heart malformations, kidney malformations, brain malformations), resulting in medical termination for three probands. In the fourth, the only one alive at birth, proband born at 39+5 weeks, normal growth parameters after pregnancy with polyhydramnios, corpus callosum agenesis and polydactyly. Respiratory distress at birth. All four probands presented typical features of ciliopathy disorders, overlapping with oral, facial and digital abnormalities. All with homozygous missense variants. All absent in gnomAD (in homozygous state). Sanger sequencing confirmed mode of inheritance. Sources: Literature |

Lucy Spencer gene: MIR145 was added gene: MIR145 was added to Mendeliome. Sources: Literature Mode of inheritance for gene: MIR145 was set to MONOALLELIC, autosomal or pseudoautosomal, imprinted status unknown Publications for gene: MIR145 were set to 36649075 Phenotypes for gene: MIR145 were set to multisystemic smooth muscle dysfunction syndrome (MONDO:0013452), MIR145-related Review for gene: MIR145 was set to RED Added comment: PMID: 36649075- a patient whose fetal ultrasound revealed polyhydramnios, enlarged abdomenand bladder, and prune belly syndrome. 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. RNA-seq showed that the differentially expressed genes were substantially different between patient and control fibroblasts. Sources: Literature |

| Mendeliome v1.489 | PIGN |
Zornitza Stark edited their review of gene: PIGN: Added comment: Large cohort study of 21 new and review of 40 previously published cases in PMID 36322149 Biallelic-truncating variants were detected in 16 patients-10 with Fryns syndrome, 1 with MCAHS1, 2 with Fryns syndrome/MCAHS1, and 3 with neurologic phenotype. There was an increased risk of prenatal or neonatal death within this group (6 deaths were in utero or within 2 months of life; 6 pregnancies were terminated). Incidence of polyhydramnios, congenital anomalies (eg, diaphragmatic hernia), and dysmorphism was significantly increased. Biallelic missense or mixed genotype were reported in the remaining 45 cases-32 showed a neurologic phenotype and 12 had MCAHS1. No cases of diaphragmatic hernia or abdominal wall defects were seen in this group except patient 1 in which we found the missense variant p.Ser893Arg to result in functionally null alleles, suggesting the possibility of an undescribed functionally important region in the final exon.; Changed publications: 36322149; Changed phenotypes: Multiple congenital anomalies-hypotonia-seizures syndrome 1, MIM# 614080, MONDO:0013563, Fryns syndrome |

Zornitza Stark changed review comment from: Two individuals reported with same missense variant and hypopigmentation, organomegaly, and delayed myelination and development. Variant is GoF. No osteopetrosis, biopsy findings from skin and other organs are consistent with a lysosomal storage disorder. IUGR, prematurity and polyhydramnios are features. Bi-allelic variants in this gene are associated with osteopetrosis.; to: Two individuals reported with same missense variant and hypopigmentation, organomegaly, and delayed myelination and development.
