RCV001896951 | SCV002171176 | uncertain significance | LAMA2-related muscular dystrophy | 2021-09-17 | criteria provided, single submitter | clinical testing | This sequence change replaces methionine with valine at codon 1768 of the LAMA2 protein (p.Met1768Val). The methionine residue is weakly conserved and there is a small physicochemical difference between methionine and valine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with LAMA2-related conditions. 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 LAMA2 protein function. 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. |
