Labcorp Genetics (formerly Invitae), Labcorp RCV001912838 SCV002170516 pathogenic Episodic ataxia type 2; Developmental and epileptic encephalopathy, 42 2022-06-09 criteria provided, single submitter clinical testing For these reasons, this variant has been classified as Pathogenic. 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). This sequence change creates a premature translational stop signal (p.Cys281Alafs*29) in the CACNA1A gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in CACNA1A are known to be pathogenic (PMID: 10371528, 19486177, 25735478, 27250579).
