Description

In summary, this variant is a novel missense change with uncertain impact on protein function. 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 do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). This variant is not present in population databases (ExAC no frequency) and has not been reported in the literature in individuals with a RYR1-related disease. This sequence change replaces glutamine with histidine at codon 3899 of the RYR1 protein (p.Gln3899His). The glutamine residue is moderately conserved and there is a small physicochemical difference between glutamine and histidine.
