Labcorp Genetics (formerly Invitae), Labcorp RCV001295279 SCV001484194 uncertain significance Episodic ataxia type 2; Developmental and epileptic encephalopathy, 42 2020-06-05 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. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site, but this prediction has not been confirmed by published transcriptional studies. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with CACNA1A-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces proline with glutamine at codon 1129 of the CACNA1A protein (p.Pro1129Gln). The proline residue is moderately conserved and there is a moderate physicochemical difference between proline and glutamine.
