Description

This sequence change replaces arginine with serine at codon 1038 of the SCN10A protein (p.Arg1038Ser). The arginine residue is weakly conserved and there is a moderate physicochemical difference between arginine and serine. This variant is present in population databases (rs773394234, ExAC 0.002%). This variant has not been reported in the literature in individuals with SCN10A-related conditions. ClinVar contains an entry for this variant (Variation ID: 809460). 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 SCN10A 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.
