Description
This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 204 of the EMD protein (p.Arg204Cys). This variant is present in population databases (rs782299893, gnomAD 0.005%), including at least one homozygous and/or hemizygous individual. This variant has not been reported in the literature in individuals affected with EMD-related conditions. ClinVar contains an entry for this variant (Variation ID: 201776). 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 EMD 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.
