rs1801725

rs1801725 is the CASR Ala986Ser (A986S) missense variant in the calcium-sensing receptor gene, located in the receptor's cytoplasmic tail. The Ser986 allele produces a less-active receptor with reduced sensitivity to extracellular calcium, shifting the calcium set-point and associating with modestly higher serum calcium and parathyroid hormone levels. Along with CYP24A1 rs1570669, it is used as inherited context for calcium status within the normal range.
