RCV001880039 | SCV002283697 | uncertain significance | Episodic ataxia type 2; Developmental and epileptic encephalopathy, 42 | 2022-12-15 | 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. 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) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on CACNA1A protein function. ClinVar contains an entry for this variant (Variation ID: 982692). This variant has not been reported in the literature in individuals affected with CACNA1A-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 1234 of the CACNA1A protein (p.Arg1234Cys). |
