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]

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.10346A>G (p.E3449G) alteration is located in exon 73 (coding exon 73) of the RYR3 gene. This alteration results from a A to G substitution at nucleotide position 10346, causing the glutamic acid (E) at amino acid position 3449 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This sequence change replaces glutamic acid, which is acidic and polar, with glycine, which is neutral and non-polar, at codon 3449 of the RYR3 protein (p.Glu3449Gly). This variant is present in population databases (rs756934182, gnomAD 0.007%). 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: 572379). 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"). 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. -
