Invitae RCV001041193 SCV001204795 uncertain significance Episodic ataxia type 2; Developmental and epileptic encephalopathy, 42 2024-01-13 criteria provided, single submitter clinical testing This sequence change replaces glycine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 2072 of the CACNA1A protein (p.Gly2072Ser). This variant is present in population databases (rs370514102, gnomAD 0.004%). This variant has not been reported in the literature in individuals affected with CACNA1A-related conditions. ClinVar contains an entry for this variant (Variation ID: 839437). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt CACNA1A protein function with a negative predictive value of 95%. 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.
