Summaries for RYR1 Gene

Entrez Gene Summary for RYR1 Gene

  • 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]

GeneCards Summary for RYR1 Gene

RYR1 (Ryanodine Receptor 1 (Skeletal)) is a Protein Coding gene. Diseases associated with RYR1 include minicore myopathy with external ophthalmoplegia and central core disease. Among its related pathways are CREB Pathway and Activation of cAMP-Dependent PKA. GO annotations related to this gene include calcium ion binding and protease binding. An important paralog of this gene is RYR3.

UniProtKB/Swiss-Prot for RYR1 Gene

  • Calcium channel that mediates the release of Ca(2+) from the sarcoplasmic reticulum into the cytoplasm and thereby plays a key role in triggering muscle contraction following depolarization of T-tubules. Repeated very high-level exercise increases the open probability of the channel and leads to Ca(2+) leaking into the cytoplasm. Can also mediate the release of Ca(2+) from intracellular stores in neurons, and may thereby promote prolonged Ca(2+) signaling in the brain. Required for normal embryonic development of muscle fibers and skeletal muscle. Required for normal heart morphogenesis, skin development and ossification during embryogenesis (By similarity).

    Quaternary structure:
    • Homotetramer. Can also form heterotetramers with RYR2. Interacts with CALM; CALM with bound calcium inhibits the RYR1 channel activity. Interacts with S100A1. Interacts with FKBP1A; this stabilizes the closed conformation of the channel. Interacts with CACNA1S; interaction with CACNA1S is important for activation of the RYR1 channel. Interacts with CACNB1. Interacts with TRDN and ASPH; these interactions stimulate RYR1 channel activity (By similarity). Identified in a complex composed of RYR1, PDE4D, PKA, FKBP1A and protein phosphatase 1 (PP1). Repeated very high-level exercise decreases interaction with PDE4D and protein phosphatase 1 (PP1).
    • Channel activity is modulated by the alkaloid ryanodine that binds to the open Ca-release channel with high affinity. At low concentrations, ryanodine maintains the channel in an open conformation. High ryanodine concentrations inhibit channel activity. Channel activity is regulated by calmodulin (CALM). The calcium release is activated by increased cytoplasmic calcium levels, by nitric oxyde (NO), caffeine and ATP. Channel activity is inhibited by magnesium ions, possibly by competition for calcium binding sites (By similarity).
    • Coexpression of normal and mutant Thr-4898 RYR1 in a 1:1 ratio, produces RYR1 channels with normal halothane and caffeine sensitivities, but maximal levels of Ca(2+) release are reduced by 67%. Binding of [3H]ryanodine indicates that the heterozygous channel is activated by Ca(2+) concentrations 4-fold lower than normal. Single-cell analysis of cotransfected cells shows a significantly increased resting cytoplasmic Ca(2+) level and a significantly reduced luminal Ca(2+) level. These data indicated a leaky channel, possibly caused by a reduction in the Ca(2+) concentration required for channel activation. Comparison with 2 other coexpressed mutant/normal channels suggests that the Thr-4898 mutation produces one of the most abnormal RYR1 channels that has been investigated, and this level of abnormality is reflected in the severe and penetrant phenotype of affected CCD individuals

(3) OMIM Diseases for RYR1 Gene (180901)


  • Malignant hyperthermia 1 (MHS1) [MIM:145600]: Autosomal dominant pharmacogenetic disorder of skeletal muscle and is one of the main causes of death due to anesthesia. In susceptible people, an MH episode can be triggered by all commonly used inhalational anesthetics such as halothane and by depolarizing muscle relaxants such as succinylcholine. The clinical features of the myopathy are hyperthermia, accelerated muscle metabolism, contractures, metabolic acidosis, tachycardia and death, if not treated with the postsynaptic muscle relaxant, dantrolene. Susceptibility to MH can be determined with the in vitro contracture test (IVCT): observing the magnitude of contractures induced in strips of muscle tissue by caffeine alone and halothane alone. Patients with normal response are MH normal (MHN), those with abnormal response to caffeine alone or halothane alone are MH equivocal (MHE(C) and MHE(H) respectively). {ECO:0000269 PubMed:10051009, ECO:0000269 PubMed:10484775, ECO:0000269 PubMed:10612851, ECO:0000269 PubMed:10823104, ECO:0000269 PubMed:10888602, ECO:0000269 PubMed:11241852, ECO:0000269 PubMed:11389482, ECO:0000269 PubMed:11525881, ECO:0000269 PubMed:11575529, ECO:0000269 PubMed:11928716, ECO:0000269 PubMed:12059893, ECO:0000269 PubMed:12066726, ECO:0000269 PubMed:12123492, ECO:0000269 PubMed:12208234, ECO:0000269 PubMed:12411788, ECO:0000269 PubMed:12709367, ECO:0000269 PubMed:12883402, ECO:0000269 PubMed:1354642, ECO:0000269 PubMed:14732627, ECO:0000269 PubMed:14985404, ECO:0000269 PubMed:15221887, ECO:0000269 PubMed:15448513, ECO:0000269 PubMed:16163667, ECO:0000269 PubMed:1774074, ECO:0000269 PubMed:19191329, ECO:0000269 PubMed:20142353, ECO:0000269 PubMed:20681998, ECO:0000269 PubMed:23558838, ECO:0000269 PubMed:24013571, ECO:0000269 PubMed:7751854, ECO:0000269 PubMed:7849712, ECO:0000269 PubMed:7881417, ECO:0000269 PubMed:8012359, ECO:0000269 PubMed:9066328, ECO:0000269 PubMed:9138151, ECO:0000269 PubMed:9389851, ECO:0000269 PubMed:9450902, ECO:0000269 PubMed:9497245}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Central core disease of muscle (CCD) [MIM:117000]: Autosomal dominant congenital myopathy, but a severe autosomal recessive form also exists. Both clinical and histological variability is observed. Affected individuals typically display hypotonia and proximal muscle weakness in infancy, leading to the delay of motor milestones. The clinical course of the disorder is usually slow or nonprogressive in adulthood, and the severity of the symptoms may vary from normal to significant muscle weakness. Microscopic examination of CCD-affected skeletal muscle reveals a predominance of type I fibers containing amorphous-looking areas (cores) that do not stain with oxidative and phosphorylase histochemical techniques. {ECO:0000269 PubMed:10051009, ECO:0000269 PubMed:10097181, ECO:0000269 PubMed:11113224, ECO:0000269 PubMed:11709545, ECO:0000269 PubMed:11741831, ECO:0000269 PubMed:12112081, ECO:0000269 PubMed:12136074, ECO:0000269 PubMed:12565913, ECO:0000269 PubMed:12566385, ECO:0000269 PubMed:12937085, ECO:0000269 PubMed:14670767, ECO:0000269 PubMed:14985404, ECO:0000269 PubMed:17204054, ECO:0000269 PubMed:17226826, ECO:0000269 PubMed:18253926, ECO:0000269 PubMed:18312400, ECO:0000269 PubMed:20142353, ECO:0000269 PubMed:21674524, ECO:0000269 PubMed:23558838, ECO:0000269 PubMed:24561095, ECO:0000269 PubMed:7829078, ECO:0000269 PubMed:8220422, ECO:0000269 PubMed:8220423, ECO:0000269 PubMed:9497245}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Multiminicore disease with external ophthalmoplegia (MMDO) [MIM:255320]: Clinically heterogeneous neuromuscular disorder. General features include neonatal hypotonia, delayed motor development, and generalized muscle weakness and amyotrophy, which may progress slowly or remain stable. Muscle biopsy shows multiple, poorly circumscribed, short areas of sarcomere disorganization and mitochondria depletion (areas termed minicores) in most muscle fibers. Typically, no dystrophic signs, such as muscle fiber necrosis or regeneration or significant endomysial fibrosis, are present in multiminicore disease. {ECO:0000269 PubMed:12719381, ECO:0000269 PubMed:16380615}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Myopathy, congenital, with fiber-type disproportion (CFTD) [MIM:255310]: A genetically heterogeneous disorder in which there is relative hypotrophy of type 1 muscle fibers compared to type 2 fibers on skeletal muscle biopsy. However, these findings are not specific and can be found in many different myopathic and neuropathic conditions. {ECO:0000269 PubMed:20583297}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Note=Defects in RYR1 may be a cause of Samaritan myopathy, a congenital myopathy with benign course. Patients display severe hypotonia and respiratory distress at birth. Unlike other congenital myopathies, the health status constantly improves and patients are minimally affected at adulthood.
