This sequence change replaces histidine, which is basic and polar, with glutamine, which is neutral and polar, at codon 1384 of the EPG5 protein (p.His1384Gln). This variant is present in population databases (rs200079588, gnomAD 0.05%). This variant has not been reported in the literature in individuals affected with EPG5-related conditions. ClinVar contains an entry for this variant (Variation ID: 570618). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The glutamine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect 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. -

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
