RCV004788229 | SCV005398723 | pathogenic | Congenital myopathy | 2022-02-02 | criteria provided, single submitter | clinical testing | Based on the classification scheme VCGS_Germline_v1.3.4, this variant is classified as Pathogenic. Following criteria are met: 0102 - Loss of function is a known mechanism of disease in this gene and is associated with congenital myopathy (PMID: 28012042). (I) 0108 - This gene is associated with both recessive and dominant disease. A number of dominant conditions are associated with this gene (OMIM), however congenital myopathy involving frameshift variants is inherited in a recessive manner (PMID: 28012042). (I) 0201 - Variant is predicted to cause nonsense-mediated decay (NMD) and loss of protein (premature termination codon is located at least 54 nucleotides upstream of the final exon-exon junction). (SP) 0251 - This variant is heterozygous. (I) 0301 - Variant is absent from gnomAD (both v2 and v3). (SP) 0702 - Other NMD-predicted variants comparable to the one identified in this case have strong previous evidence for pathogenicity. At least six other frameshifts have been reported in compound heterozygosity with missense variants in individuals with autosomal recessive congenital myopathy (PMID: 26247046, PMID: 28012042). (SP) 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) 1203 - This variant has been shown to be de novo in the proband (parental status confirmed) (by trio analysis). (SP) Legend: (SP) - Supporting pathogenic, (I) - Information, (SB) - Supporting benign |
