Invitae RCV001038979 SCV001202484 uncertain significance Familial hemiplegic migraine 2023-07-07 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. ClinVar contains an entry for this variant (Variation ID: 837603). This variant has not been reported in the literature in individuals affected with ATP1A2-related conditions. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This sequence change replaces threonine, which is neutral and polar, with alanine, which is neutral and non-polar, at codon 417 of the ATP1A2 protein (p.Thr417Ala).
