Labcorp Genetics (formerly Invitae), Labcorp RCV003510213 SCV004327249 uncertain significance Generalized epilepsy-paroxysmal dyskinesia syndrome 2023-09-27 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 expected to disrupt KCNMA1 protein function. This variant has not been reported in the literature in individuals affected with KCNMA1-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces tyrosine, which is neutral and polar, with aspartic acid, which is acidic and polar, at codon 1072 of the KCNMA1 protein (p.Tyr1072Asp).
