Labcorp Genetics (formerly Invitae), Labcorp RCV002036635 SCV002317682 uncertain significance Episodic ataxia type 2; Developmental and epileptic encephalopathy, 42 2020-11-04 criteria provided, single submitter clinical testing This sequence change replaces glycine with alanine at codon 22 of the CACNA1A protein (p.Gly22Ala). The glycine residue is moderately conserved and there is a small physicochemical difference between glycine and alanine. This variant is not present in population databases (ExAC no frequency). 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 CACNA1A protein function. This variant has not been reported in the literature in individuals with CACNA1A-related conditions.
