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 falls in intron 95 of the RYR3 gene. It does not directly change the encoded amino acid sequence of the RYR3 protein. It affects a nucleotide within the consensus splice site. This variant is present in population databases (rs780109992, gnomAD 0.009%). 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: 531036). Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. 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. -
