WebHistorically, patients with congenital myopathy due to RYR1 mutations were diagnosed based on the finding of pathologic central cores (central core disease; CCD) on muscle biopsy, which represent areas that lack oxidative enzymes and mitochondrial activity in type 1 muscle fibers. WebRYR1 channels play a critical role in muscles used for movement (skeletal muscles). For the body to move normally, skeletal muscles must tense (contract) and relax in a coordinated way. Muscle contractions are triggered by an increase in the concentration of calcium ions inside muscle cells.
