Invitae | RCV000817288 | SCV000957838 | likely pathogenic | LAMA2-related muscular dystrophy | 2021-08-12 | criteria provided, single submitter | clinical testing | This variant is a gross deletion of the genomic region encompassing exon(s) 9-12 of the LAMA2 gene. This variant would be expected to be in-frame, preserving the integrity of the reading frame. This variant has not been reported in the literature in individuals affected with LAMA2-related conditions. This variant disrupts the p.Cys527 amino acid residue in LAMA2. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 12552556, 23326386). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. |
