RCV002272955 | SCV002557447 | uncertain significance | Autosomal dominant childhood-onset proximal spinal muscular atrophy without contractures | 2022-06-24 | criteria provided, single submitter | clinical testing | Based on the classification scheme VCGS_Germline_v1.3.4, this variant is classified as VUS-3B. Following criteria are met: 0103 - Loss of function and gain of function are known mechanisms of disease in this gene and are associated with spinal muscular atrophy, lower extremity-predominant 1 (MIM#158600), intellectual disability (MIM#614563) and Charcot-Marie-Tooth disease, axonal, type 20 (MIM#614228). While there is no clear genotype-phenotype correlation, there is some association between the severity of the variant on protein function and the phenotype that is manifested (PMIDs: 25512093, 28196890). (I) 0107 - This gene is associated with autosomal dominant disease. (I) 0115 - Variants in this gene are known to have variable expressivity, with intrafamilial variation reported (PMID: 25512093). (I) 0200 - Variant is predicted to result in a missense amino acid change from phenylalanine to tyrosine. (I) 0251 - This variant is heterozygous. (I) 0301 - Variant is absent from gnomAD (both v2 and v3). (SP) 0502 - Missense variant with conflicting in silico predictions and uninformative conservation. (I) 0604 - Variant is not located in an established domain, motif, hotspot or informative constraint region. (I) 0705 - No comparable missense variants have previous evidence for pathogenicity. (I) 0807 - This variant has no previous evidence of pathogenicity. (I) 0905 - No published segregation evidence has been identified for this variant. (I) 1007 - No published functional evidence has been identified for this variant. (I) 1208 - Inheritance information for this variant is not currently available in this individual. (I) Legend: (SP) - Supporting pathogenic, (I) - Information, (SB) - Supporting benign |
