Invitae RCV001033733 SCV001197040 pathogenic Glycogen storage disease, type V 2021-08-04 criteria provided, single submitter clinical testing This variant is a gross deletion of the genomic region encompassing exon(s) 2-4 of the PYGM gene. This variant would be expected to be in-frame, preserving the integrity of the reading frame. A similar copy number variant has been observed in individual(s) with McArdle disease (Invitae). In at least one individual the data is consistent with the variant being in trans (on the opposite chromosome) from a pathogenic variant. This variant disrupts the p.Arg94 amino acid residue in PYGM. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 12508303, 17324573, 17404776, 17994553, 19472443, 22250184). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic.
