RCV003122207 | SCV003788816 | pathogenic | Autosomal recessive limb-girdle muscular dystrophy type 2C | 2022-10-19 | criteria provided, single submitter | clinical testing | This variant is a gross deletion of the genomic region encompassing exon(s) 8 of the SGCG gene, which includes the termination codon. This deletion extends beyond the assayed region for this gene and therefore may encompass additional genes. While this deletion is not anticipated to lead to nonsense mediated decay, it is expected to alter mRNA translation or result in a truncated protein product. A similar copy number variant has been observed in individual(s) with SGCG-related conditions (PMID: 18285821). This variant disrupts a region of the SGCG protein in which other variant(s) (p.Thr251Serfs*29) have been determined to be pathogenic (Invitae). This suggests that this is a clinically significant region of the protein, and that variants that disrupt it are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic. |
