Labcorp Genetics (formerly Invitae), Labcorp RCV003044026 SCV003338703 uncertain significance Lethal congenital glycogen storage disease of heart 2022-11-01 criteria provided, single submitter clinical testing This variant has not been reported in the literature in individuals affected with PRKAG2-related conditions. 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 disruptive. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces leucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 547 of the PRKAG2 protein (p.Leu547Val).
