Invitae RCV001304572 SCV001493859 uncertain significance Glycogen storage disease due to muscle and heart glycogen synthase deficiency 2022-06-27 criteria provided, single submitter clinical testing This variant is not present in population databases (gnomAD no frequency). 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 create or strengthen a splice site. 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"). ClinVar contains an entry for this variant (Variation ID: 1007393). This variant has not been reported in the literature in individuals affected with GYS1-related conditions. This sequence change replaces asparagine, which is neutral and polar, with serine, which is neutral and polar, at codon 376 of the GYS1 protein (p.Asn376Ser).
