Invitae RCV001059789 SCV001224436 uncertain significance RYR1-Related Disorders 2019-05-10 criteria provided, single submitter clinical testing 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: "Possibly Damaging"; Align-GVGD: "Class C0"). 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 sequence change is located in a region of the RYR1 protein where a significant number of previously reported RYR1 missense mutations are found (PMID: 16084090). 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 valine with glutamic acid at codon 4855 of the RYR1 protein (p.Val4855Glu). The valine residue is highly conserved and there is a moderate physicochemical difference between valine and glutamic acid.
