1. Segregation analysis is of limited value in assessing pathogenicity of RYR1 variants in malignant hyperthermia PMID: 28403410
2. 49 RYR1 variants were identified in 47 cases. In recessive cases, facial weakness, neonatal hypotonia, ophthalmoplegia/paresis, ptosis, and scapular winging were more frequently observed than in dominant/de novo cases.

14. Data suggest that reduced SOICR (store overload-induced Ca2+ release) threshold is a common defect of malignant hyperthermia- or central core disease-associated RyR1 mutations; carvedilol (a beta-blocker), like dantrolene (a central muscle relaxant), can suppress RyR1-mediated SOICR. Here, human disease-associated point mutations were induced in recombinant rabbit RyR1 via site-directed mutagenesis. PMID: 28687594
15. results suggest that nine RyR1 mutants associated with skeletal muscle diseases were differently regulated by Ca(2+) and Mg(2+) Four malignant hyperthermia-associated RyR1 mutations in the S2-S3 loop conferred RyR2-type Ca(2+)- and Mg(2+)-dependent channel regulation PMID: 27558158
