RCV001051662 | SCV001215830 | uncertain significance | Episodic ataxia type 2; Developmental and epileptic encephalopathy, 42 | 2019-05-19 | criteria provided, single submitter | clinical testing | 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: "Benign"; 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). 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. This sequence change replaces aspartic acid with tyrosine at codon 903 of the CACNA1A protein (p.Asp903Tyr). The aspartic acid residue is weakly conserved and there is a large physicochemical difference between aspartic acid and tyrosine. |
