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 variant is present in population databases (rs368466725, gnomAD 0.1%), and has an allele count higher than expected for a pathogenic variant. 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) performed at Invitae indicates that this missense variant is expected to disrupt RYR3 protein function. ClinVar contains an entry for this variant (Variation ID: 569729). This variant has not been reported in the literature in individuals affected with RYR3-related conditions. This sequence change replaces alanine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 4650 of the RYR3 protein (p.Ala4650Thr). -
