Invitae RCV001041446 SCV001205066 uncertain significance Lethal congenital glycogen storage disease of heart 2022-09-12 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 sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. 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 expected to disrupt PRKAG2 protein function. ClinVar contains an entry for this variant (Variation ID: 839643). This missense change has been observed in individual(s) with PRKAG2-related conditions (PMID: 31720784). This variant is not present in population databases (gnomAD no frequency). This sequence change replaces alanine, which is neutral and non-polar, with glycine, which is neutral and non-polar, at codon 304 of the PRKAG2 protein (p.Ala304Gly).
