Genes affected

RYR3 (HGNC:10485): (ryanodine receptor 3) The protein encoded by this gene is a ryanodine receptor, which functions to release calcium from intracellular storage for use in many cellular processes. For example, the encoded protein is involved in skeletal muscle contraction by releasing calcium from the sarcoplasmic reticulum followed by depolarization of T-tubules. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2011]

This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 2781 of the RYR3 protein (p.Arg2781Gln). This variant is present in population databases (rs375015024, gnomAD 0.03%). This variant has not been reported in the literature in individuals affected with RYR3-related conditions. ClinVar contains an entry for this variant (Variation ID: 570829). 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: "Probably 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. -
