RCV002471798 | SCV002766747 | pathogenic | Muscular dystrophy-dystroglycanopathy (congenital with brain and eye anomalies), type A, 7 | 2022-03-31 | 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 muscular dystrophy-dystroglycanopathy (congenital with brain and eye anomalies), type A, 7 (MIM#614643) and muscular dystrophy-dystroglycanopathy (limb-girdle), type C, 7 (MIM#616052). (I) 0106 - This gene is associated with autosomal recessive disease. (I) 0211 - Canonical splice site variant without proven consequence on splicing (no functional evidence available). (SP) 0251 - This variant is heterozygous. (I) 0301 - Variant is absent from gnomAD (both v2 and v3). (SP) 0505 - Abnormal splicing is predicted by in silico tools and affected nucleotide is highly conserved. (SP) 0703 - Two canonical splice site variants comparable to the one identified in this case have moderate previous evidence for pathogenicity. One alternative canonical splice site variant, c.258-1G>C, has been reported as pathogenic and likely pathogenic in ClinVar and also in a heterozygous individual from a cohort of inherited muscular disorders (PMID: 27363342). And the other one, c.258-1G>A has been reported in a compound heterozygous individual with Walker Warburg Syndrome (PMID: 28688748). (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) 1205 - This variant has been shown to be maternally inherited (by trio analysis). (I) Legend: (SP) - Supporting pathogenic, (I) - Information, (SB) - Supporting benign |
