Invitae RCV001070663 SCV001235927 uncertain significance RYR1-Related Disorders 2019-02-26 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. This missense change is located in a region of the RYR1 protein where a significant number of previously reported RYR1 missense mutations are found (PMID: 16084090). These observations suggest that a previously unreported missense substitution within this region may affect protein function, but experiments have not been done to test this possibility. 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"). This variant has not been reported in the literature in individuals with RYR1-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces arginine with cysteine at codon 4188 of the RYR1 protein (p.Arg4188Cys). The arginine residue is moderately conserved and there is a large physicochemical difference between arginine and cysteine.
