Labcorp Genetics (formerly Invitae), Labcorp RCV000654660 SCV000776557 uncertain significance Hyperkalemic periodic paralysis 2023-09-01 criteria provided, single submitter clinical testing 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 SCN4A protein function. ClinVar contains an entry for this variant (Variation ID: 543807). This variant has not been reported in the literature in individuals affected with SCN4A-related conditions. This variant is present in population databases (rs767053007, gnomAD 0.009%). This sequence change replaces asparagine, which is neutral and polar, with serine, which is neutral and polar, at codon 916 of the SCN4A protein (p.Asn916Ser). 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.
