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]

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

Variant identified in a genome or exome case(s) and assessed due to predicted null impact of the variant or pathogenic assertions in the literature or databases. Disclaimer: This variant has not undergone full assessment. The following are preliminary notes: This variant has been reported in one patient with axial myopathy and one who is malignant hyperthermia susceptible as determined by the Caffeine contracture test. The variant has a Max MAF of 0.1% in ExAC (19 South Asian alleles) and 0.1% in gnomAD (35 South Asian alleles). Frequency is too high for disease. It is classified with 1 star in ClinVar as VUS by GeneDx and as Likely benign by CSER_CC_NCGL. -
