RCV002037543 | SCV002115607 | uncertain significance | Glycogen storage disease due to muscle and heart glycogen synthase deficiency | 2021-07-12 | 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 missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. This variant has not been reported in the literature in individuals affected with GYS1-related conditions. This variant is present in population databases (rs764543224, ExAC 0.002%). This sequence change replaces lysine with glutamic acid at codon 97 of the GYS1 protein (p.Lys97Glu). The lysine residue is moderately conserved and there is a small physicochemical difference between lysine and glutamic acid. |
