RCV001306423 | SCV001495795 | uncertain significance | Episodic ataxia type 2; Developmental and epileptic encephalopathy, 42 | 2020-06-17 | criteria provided, single submitter | clinical testing | This sequence change replaces arginine with serine at codon 2109 of the CACNA1A protein (p.Arg2109Ser). The arginine residue is moderately conserved and there is a moderate physicochemical difference between arginine and serine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with CACNA1A-related conditions. 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: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). 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. |
