Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the RYR1 gene is commonly pathogenic or not.

In the table, we include only reliable ClinVar variants with their consequences to MANE Select, Mane Plus Clinical transcripts, or transcripts with TSL equals 1. Click the count to view the source variants.

Warning: slight differences between displayed counts and the number of variants in ClinVar may occur, primarily due to (1) the application of a different transcript and/or consequence by our variant effect predictor or (2) differences in clinical significance: we classify Benign/Likely benign variants as Likely benign and Pathogenic/Likely pathogenic variants as Likely pathogenic.

Function
FUNCTION: 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 (PubMed:11741831, PubMed:16163667). Repeated very high-level exercise increases the open probability of the channel and leads to Ca(2+) leaking into the cytoplasm (PubMed:18268335). 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). {ECO:0000250|UniProtKB:E9PZQ0, ECO:0000269|PubMed:18268335, ECO:0000305|PubMed:11741831, ECO:0000305|PubMed:16163667}.;
Disease
DISEASE: 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:19685112, ECO:0000269|PubMed:20142353, ECO:0000269|PubMed:20681998, ECO:0000269|PubMed:23558838, ECO:0000269|PubMed:24013571, ECO:0000269|PubMed:26115329, ECO:0000269|PubMed:26381711, ECO:0000269|PubMed:26631338, ECO:0000269|PubMed:27586648, ECO:0000269|PubMed:7751854, ECO:0000269|PubMed:7849712, ECO:0000269|PubMed:7881417, ECO:0000269|PubMed:8012359, ECO:0000269|PubMed:8220423, ECO:0000269|PubMed:9066328, ECO:0000269|PubMed:9138151, ECO:0000269|PubMed:9389851, ECO:0000269|PubMed:9450902, ECO:0000269|PubMed:9497245}. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.; DISEASE: 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: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:26381711, ECO:0000269|PubMed:27234031, ECO:0000269|PubMed:27586648, 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.; DISEASE: 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, ECO:0000269|PubMed:20583297}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: 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.;
