NCIt definition : Human CASR wild-type allele is located within 3q13.33-q21.1 and is approximately 108
kb in length. This allele, which encodes extracellular calcium-sensing receptor protein,
plays a role in G-protein-coupled receptor signaling in response to changes in circulating
calcium concentration. Mutations in the gene are associated with idiopathic generalized
epilepsy 8, severe neonatal hyperparathyroidism, familial hypocalciuric hypercalcemia
type 1 and autosomal dominant hypocalcemia 1, with or without Bartter Syndrome.;
