Labcorp Genetics (formerly Invitae), Labcorp RCV003783866 SCV004571625 uncertain significance Hypokalemic periodic paralysis, type 1; Malignant hyperthermia, susceptibility to, 5 2023-03-24 criteria provided, single submitter clinical testing This sequence change replaces glycine, which is neutral and non-polar, with aspartic acid, which is acidic and polar, at codon 1285 of the CACNA1S protein (p.Gly1285Asp). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with clinical features of congenital myopathy (Invitae). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. 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 expected to disrupt CACNA1S 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.
