Invitae RCV000687520 SCV000815092 uncertain significance Glycogen storage disease due to muscle and heart glycogen synthase deficiency 2022-08-08 criteria provided, single submitter clinical testing This sequence change replaces glutamic acid, which is acidic and polar, with glycine, which is neutral and non-polar, at codon 132 of the GYS1 protein (p.Glu132Gly). This variant is present in population databases (rs183816843, gnomAD 0.009%). This variant has not been reported in the literature in individuals affected with GYS1-related conditions. ClinVar contains an entry for this variant (Variation ID: 567434). 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: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). 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.
