title: [Pathophysiology of Hypoparathyroidism].
abstract: Hypoparathyroidism in a broad sense is caused by a parathyroid hormone (PTH) deficiency or resistance, leading to hypocalcemia and hyperphosphatemia. PTH deficiency can be result from destruction or hypoplasia/agenesis of the parathyroid gland, or the impaired synthesis or secretion of PTH. On the other hand, PTH resistance is based on the disrupted transduction of its signaling and includes pseudohypoparathyroidism, Blomstrand lethal chondrodysplasia and acrodysostosis. There has been a substantial progress in the identification of the pathogenesis for the inherited hypoparathyroidism, and genetic tests for diagnosis are considered when necessary.
