Labcorp Genetics (formerly Invitae), Labcorp RCV002003087 SCV002277129 uncertain significance Lethal congenital glycogen storage disease of heart 2021-07-30 criteria provided, single submitter clinical testing This variant has not been reported in the literature in individuals affected with PRKAG2-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces glutamic acid with aspartic acid at codon 515 of the PRKAG2 protein (p.Glu515Asp). The glutamic acid residue is highly conserved and there is a small physicochemical difference between glutamic acid and aspartic acid. 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.
