RCV001890735 | SCV002147522 | uncertain significance | Glycogen storage disease due to muscle and heart glycogen synthase deficiency | 2022-02-27 | criteria provided, single submitter | clinical testing | This sequence change replaces threonine, which is neutral and polar, with isoleucine, which is neutral and non-polar, at codon 84 of the GYS1 protein (p.Thr84Ile). This variant is present in population databases (rs143186691, gnomAD 0.007%). 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 (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. 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. |
