Labcorp Genetics (formerly Invitae), Labcorp RCV002045520 SCV002297186 uncertain significance Familial hemiplegic migraine 2024-02-16 criteria provided, single submitter clinical testing This sequence change replaces arginine, which is basic and polar, with proline, which is neutral and non-polar, at codon 7 of the ATP1A2 protein (p.Arg7Pro). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with clinical features of ATP1A2-related conditions (Invitae). ClinVar contains an entry for this variant (Variation ID: 1503799). 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) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on ATP1A2 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.
