Labcorp Genetics (formerly Invitae), Labcorp RCV003587859 SCV004322375 uncertain significance Familial hemiplegic migraine 2023-09-10 criteria provided, single submitter clinical testing 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 ATP1A2 protein function. This variant has not been reported in the literature in individuals affected with ATP1A2-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces arginine, which is basic and polar, with threonine, which is neutral and polar, at codon 471 of the ATP1A2 protein (p.Arg471Thr).
