Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpSep 12, 2022This variant is present in population databases (rs767558102, gnomAD 0.006%). This sequence change replaces methionine, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 383 of the FAM46A protein (p.Met383Leu). This variant has not been reported in the literature in individuals affected with FAM46A-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 FAM46A protein function. -
