RCV001342623 | SCV001536567 | uncertain significance | Lethal congenital glycogen storage disease of heart | 2020-09-20 | criteria provided, single submitter | clinical testing | This sequence change replaces glutamic acid with glycine at codon 247 of the PRKAG2 protein (p.Glu247Gly). The glutamic acid residue is moderately conserved and there is a moderate physicochemical difference between glutamic acid and glycine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with PRKAG2-related conditions. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt PRKAG2 protein function. 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. |
