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]

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.19G>A (p.G7R) alteration is located in exon 1 (coding exon 1) of the RYR3 gene. This alteration results from a G to A substitution at nucleotide position 19, causing the glycine (G) at amino acid position 7 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
