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]

The c.7679G>A (p.R2560Q) alteration is located in exon 51 (coding exon 51) of the RYR3 gene. This alteration results from a G to A substitution at nucleotide position 7679, causing the arginine (R) at amino acid position 2560 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This variant has not been reported in the literature in individuals affected with RYR3-related conditions. This variant is present in population databases (rs376062318, gnomAD 0.02%). This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 2560 of the RYR3 protein (p.Arg2560Gln). ClinVar contains an entry for this variant (Variation ID: 461954). 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 are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). -
