Labcorp Genetics (formerly Invitae), Labcorp RCV003058751 SCV003448910 uncertain significance Lethal congenital glycogen storage disease of heart 2022-04-12 criteria provided, single submitter clinical testing This sequence change replaces lysine, which is basic and polar, with glutamic acid, which is acidic and polar, at codon 310 of the PRKAG2 protein (p.Lys310Glu). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected 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.
Color Diagnostics, LLC DBA Color Health RCV003533336 SCV004359747 uncertain significance Cardiomyopathy 2021-08-31 criteria provided, single submitter clinical testing This missense variant replaces lysine with glutamic acid at codon 310 of the PRKAG2 protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with cardiovascular disorders in the literature. This variant has not been identified in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance.
All of Us Research Program, National Institutes of Health RCV004009322 SCV004842235 uncertain significance Hypertrophic cardiomyopathy 2023-08-15 criteria provided, single submitter clinical testing This missense variant replaces lysine with glutamic acid at codon 310 of the PRKAG2 protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373).
