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. This variant is present in population databases (rs112800954, gnomAD 0.03%). This sequence change replaces histidine, which is basic and polar, with tyrosine, which is neutral and polar, at codon 162 of the EFHC1 protein (p.His162Tyr). This variant has not been reported in the literature in individuals affected with EFHC1-related conditions. 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: 534108). -
