Labcorp Genetics (formerly Invitae), Labcorp RCV000701418 SCV000830219 uncertain significance LAMA2-related muscular dystrophy 2022-08-23 criteria provided, single submitter clinical testing This variant is not present in population databases (gnomAD no frequency). This sequence change replaces asparagine, which is neutral and polar, with lysine, which is basic and polar, at codon 1916 of the LAMA2 protein (p.Asn1916Lys). This variant has not been reported in the literature in individuals affected with LAMA2-related conditions. 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 LAMA2 protein function. ClinVar contains an entry for this variant (Variation ID: 578417).
