RCV001359241 | SCV001555104 | uncertain significance | Vici syndrome | 2021-09-01 | criteria provided, single submitter | clinical testing | This sequence change replaces glycine with glutamic acid at codon 107 of the EPG5 protein (p.Gly107Glu). The glycine residue is weakly conserved and there is a moderate physicochemical difference between glycine and glutamic acid. This variant is present in population databases (rs766983961, ExAC 0.002%). This variant has not been reported in the literature in individuals affected with EPG5-related conditions. 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 glutamic acid 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. |
