Invitae RCV003768956 SCV001213977 uncertain significance Absence seizure; Myoclonic epilepsy, juvenile, susceptibility to, 1 2023-02-10 criteria provided, single submitter clinical testing ClinVar contains an entry for this variant (Variation ID: 846571). 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) performed at Invitae indicates that this missense variant is expected to disrupt EFHC1 protein function. This variant has not been reported in the literature in individuals affected with EFHC1-related conditions. This variant is present in population databases (rs373625101, gnomAD 0.007%). This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 153 of the EFHC1 protein (p.Arg153Trp).
