Labcorp Genetics (formerly Invitae), Labcorp RCV003800840 SCV004592464 uncertain significance Episodic ataxia type 2; Developmental and epileptic encephalopathy, 42 2023-03-09 criteria provided, single submitter clinical testing This sequence change results in a frameshift in the CACNA1A gene (p.Ala2239Thrfs*272). While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 23 amino acid(s) of the CACNA1A protein and extend the protein by 248 additional amino acid residues. This variant is not present in population databases (gnomAD 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. Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. This variant has not been reported in the literature in individuals affected with CACNA1A-related conditions.
