RCV003738747 | SCV004548567 | likely pathogenic | Qualitative or quantitative defects of dysferlin | 2024-05-20 | criteria provided, single submitter | clinical testing | This sequence change replaces valine, which is neutral and non-polar, with glutamic acid, which is acidic and polar, at codon 1856 of the DYSF protein (p.Val1856Glu). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with limb-girdle muscular dystrophy (PMID: 30098242). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt DYSF protein function with a positive predictive value of 80%. 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. |
