RCV001215162 | SCV001386891 | uncertain significance | Episodic ataxia type 2; Developmental and epileptic encephalopathy, 42 | 2021-11-28 | criteria provided, single submitter | clinical testing | ClinVar contains an entry for this variant (Variation ID: 944702). This variant has not been reported in the literature in individuals affected with CACNA1A-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.007%). This sequence change replaces methionine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 1618 of the CACNA1A protein (p.Met1618Thr). 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. 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. |
