Description

This sequence change replaces glycine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 939 of the ATP7A protein (p.Gly939Ser). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with ATP7A-related conditions. ClinVar contains an entry for this variant (Variation ID: 574362). 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 ATP7A 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.
