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]

RYR3 NM_001036.4 exon 44 p.Arg2233Gln (c.6698G>A): This variant has not been reported in the literature but is present in 0.1% (102/64580) of European alleles in the Genome Aggregation Database (https://gnomad.broadinstitute.org/variant/15-33722793-G-A?dataset=gnomad_r3). This variant is present in ClinVar (Variation ID:461938). Evolutionary conservation suggests that this variant may impact the protein; computational predictive tools for this variant are unclear. Of note, splice prediction tools suggest that this variant may affect splicing through creation of a novel splice site. However, further studies are needed to understand its impact. In summary, data on this variant is insufficient for disease classification. Therefore, the clinical significance of this variant is uncertain. -
