RCV002048493 | SCV002298265 | uncertain significance | Glycogen storage disease due to muscle and heart glycogen synthase deficiency | 2021-08-26 | criteria provided, single submitter | clinical testing | This sequence change replaces serine with threonine at codon 532 of the GYS1 protein (p.Ser532Thr). The serine residue is highly conserved and there is a small physicochemical difference between serine and threonine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals affected with GYS1-related conditions. 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 C55"). 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. |
