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]

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. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on RYR3 protein function. ClinVar contains an entry for this variant (Variation ID: 565911). This variant has not been reported in the literature in individuals affected with RYR3-related conditions. This variant is present in population databases (rs201633381, gnomAD 0.1%), and has an allele count higher than expected for a pathogenic variant. This sequence change replaces alanine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 2284 of the RYR3 protein (p.Ala2284Thr). -

This variant has not been reported in the literature but is present in the Genome Aggregation Database (Highest reported MAF 0.08% (60/68048) (https://gnomad.broadinstitute.org/variant/15-33724114-G-A?dataset=gnomad_r3). This variant is present in ClinVar (Variation ID:565911). Evolutionary conservation and computational predictive tools suggest that this variant may impact the protein. In summary, data on this variant is insufficient for disease classification. Therefore, the clinical significance of this variant is uncertain. -
