Labcorp Genetics (formerly Invitae), Labcorp RCV001059896 SCV001224550 uncertain significance Lethal congenital glycogen storage disease of heart 2019-03-05 criteria provided, single submitter clinical testing This sequence change replaces arginine with proline at codon 120 of the PRKAG2 protein (p.Arg120Pro). The arginine residue is moderately conserved and there is a moderate physicochemical difference between arginine and proline. 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 are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with PRKAG2-related conditions. This variant is not present in population databases (ExAC no frequency).
