Description

ClinVar contains an entry for this variant (Variation ID: 2155444). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. 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 not expected to disrupt CAPN3 protein function. This variant has not been reported in the literature in individuals affected with CAPN3-related conditions. This variant is present in population databases (rs564594188, gnomAD 0.003%). This sequence change replaces cysteine, which is neutral and slightly polar, with serine, which is neutral and polar, at codon 697 of the CAPN3 protein (p.Cys697Ser).
