Schematic depiction of a TAL tubular cell’s uptake of ions by the Na+,K+,2Cl−cotransporter (NKCC2). Loss-of-function mutations in the genes for NKCC2, ROMK, CLCNKB or BSND account for, respectively, Types 1–4 Bartter’s syndrome; a gain-of-function mutation in the CASR gene results in Type 5 Bartter’s syndrome. A deficiency in ROMK inhibits NKCC2 because of less K+ available to the cotransporter (K+ availability is rate-limiting); less luminal K+ results in a more negative charge that keeps Ca++ in solution thereby favoring its excretion (as opposed to its paracellular uptake). CLCNKB and BSNB are required for maintaining efflux of Cl− and are rate-limiting for the optimal function of the cotransporter. Activation of CASR by extracellular Ca++ has an effect to inhibit indirectly the cotransporter. ROMK = K+ channel; CLCNKB = Cl− channel; BSND = Bartter’s syndrome, infantile, with sensorneural deafness; also known as barttin; and CASR = Ca++ -sensing receptor.
