Considering the classical role of PTH and the muscle symptoms (muscle weakness, myopathy, etc.)that occur in hyperparathyroidism and hypoparathyroidism, it is thought that PTH may affect these musculoskeletal and neuromuscular interactions in a complex manner [6]; however, there is a lack of comprehensive information on the systemic and local effects of PTH on skeletal muscle. The gene discussed is PTH; the disease is myopathy.
