Genes affected
RYR1 (HGNC:10483): (ryanodine receptor 1) This gene encodes a ryanodine receptor found in skeletal muscle. The encoded protein functions as a calcium release channel in the sarcoplasmic reticulum but also serves to connect the sarcoplasmic reticulum and transverse tubule. Mutations in this gene are associated with malignant hyperthermia susceptibility, central core disease, and minicore myopathy with external ophthalmoplegia. Alternatively spliced transcripts encoding different isoforms have been described. [provided by RefSeq, Jul 2008]

Submissions by phenotype

RYR1-related disorder Uncertain:2
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpFeb 24, 2022This variant, c.8494_8496del, results in the deletion of 1 amino acid(s) of the RYR1 protein (p.Glu2832del), but otherwise preserves the integrity of the reading frame. This variant is present in population databases (rs767722812, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with RYR1-related conditions. ClinVar contains an entry for this variant (Variation ID: 544422). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. 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. -
Uncertain significance, no assertion criteria providedclinical testingPreventionGenetics, part of Exact SciencesJun 26, 2024The RYR1 c.8494_8496delGAG variant is predicted to result in an in-frame deletion (p.Glu2832del). To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0099% of alleles in individuals of Ashkenazi Jewish descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
