Labcorp Genetics (formerly Invitae), Labcorp RCV003516440 SCV004300902 uncertain significance Amyotrophic lateral sclerosis type 21 2023-06-20 criteria provided, single submitter clinical testing This variant is not present in population databases (gnomAD no frequency). This sequence change replaces alanine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 449 of the MATR3 protein (p.Ala449Ser). This variant has not been reported in the literature in individuals affected with MATR3-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 MATR3 protein function.
