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.5035C>A (p.H1679N) alteration is located in exon 35 (coding exon 35) of the RYR3 gene. This alteration results from a C to A substitution at nucleotide position 5035, causing the histidine (H) at amino acid position 1679 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
