Labcorp Genetics (formerly Invitae), Labcorp RCV000824171 SCV000965057 uncertain significance Lethal congenital glycogen storage disease of heart 2018-11-08 criteria provided, single submitter clinical testing 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. 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, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has not been reported in the literature in individuals with PRKAG2-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change replaces glutamic acid with lysine at codon 239 of the PRKAG2 protein (p.Glu239Lys). The glutamic acid residue is weakly conserved and there is a small physicochemical difference between glutamic acid and lysine.
