Description

This sequence change replaces alanine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 139 of the MC1R protein (p.Ala139Ser). 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 MC1R protein function. This variant has not been reported in the literature in individuals affected with MC1R-related conditions. This variant is not present in population databases (gnomAD no frequency).
