Labcorp Genetics (formerly Invitae), Labcorp RCV003770787 SCV001517643 uncertain significance Absence seizure; Myoclonic epilepsy, juvenile, susceptibility to, 1 2022-11-22 criteria provided, single submitter clinical testing This sequence change replaces lysine, which is basic and polar, with glutamic acid, which is acidic and polar, at codon 434 of the EFHC1 protein (p.Lys434Glu). This variant is present in population databases (rs771316611, gnomAD 0.003%). 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 not expected to disrupt EFHC1 protein function. ClinVar contains an entry for this variant (Variation ID: 1026185). This variant has not been reported in the literature in individuals affected with EFHC1-related conditions.
