Invitae RCV000810035 SCV000950221 uncertain significance Epilepsy, familial adult myoclonic, 5 2022-08-31 criteria provided, single submitter clinical testing This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 480 of the CNTN2 protein (p.Arg480Trp). This variant is present in population databases (rs200089665, gnomAD 0.03%). This variant has not been reported in the literature in individuals affected with CNTN2-related conditions. ClinVar contains an entry for this variant (Variation ID: 654139). 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 CNTN2 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.
