Labcorp Genetics (formerly Invitae), Labcorp RCV003806956 SCV004594380 uncertain significance Episodic ataxia type 2; Developmental and epileptic encephalopathy, 42 2023-05-22 criteria provided, single submitter clinical testing 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 CACNA1A protein function. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. 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. This sequence change replaces alanine, which is neutral and non-polar, with glycine, which is neutral and non-polar, at codon 1665 of the CACNA1A protein (p.Ala1665Gly). This variant has not been reported in the literature in individuals affected with CACNA1A-related conditions. This variant is not present in population databases (gnomAD no frequency).
