Disease

CASR_HUMAN Autosomal dominant hypocalcemia;Familial isolated hypoparathyroidism due to impaired PTH secretion;Neonatal severe primary hyperparathyroidism;Familial hypocalciuric hypercalcemia type 1;Bartter syndrome with hypocalcemia. The disease is caused by mutations affecting the gene represented in this entry. The disease is caused by mutations affecting the gene represented in this entry. The disease is caused by mutations affecting the gene represented in this entry. Disease susceptibility is associated with variations affecting the gene represented in this entry. Homozygous defects in CASR can be a cause of primary hyperparathyroidism in adulthood. Patients suffer from osteoporosis and renal calculi, have marked hypercalcemia and increased serum PTH concentrations.

Function

CASR_HUMAN Senses changes in the extracellular concentration of calcium ions. The activity of this receptor is mediated by a G-protein that activates a phosphatidylinositol-calcium second messenger system.
