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]

Epileptic encephalopathy Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingInvitaeAug 17, 2023This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 140 of the RYR3 protein (p.Arg140Trp). 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. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. ClinVar contains an entry for this variant (Variation ID: 531003). This variant has not been reported in the literature in individuals affected with RYR3-related conditions. This variant is present in population databases (rs374959679, gnomAD 0.04%). -
