Labcorp Genetics (formerly Invitae), Labcorp RCV001206174 SCV001377470 uncertain significance Vici syndrome 2021-08-31 criteria provided, single submitter clinical testing This sequence change replaces glutamic acid with lysine at codon 226 of the EPG5 protein (p.Glu226Lys). The glutamic acid residue is moderately conserved and there is a small physicochemical difference between glutamic acid and lysine. This variant is present in population databases (rs776920434, ExAC 0.006%). 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 (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. 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.
