Phenotypes observed in double KO of NCC and pendrin have led to the suggestion of pharmacologic inhibition of pendrin and NCC to provide a novel and strong diuretic regimen for patients with fluid overload, including those with congestive heart failure, nephrotic syndrome, or renal failure (35), which would induce huge Na+ and water excretion without significant K+ loss. The gene discussed is SLC12A3; the disease is acute kidney injury.
