Short chain dehydrogenase/reductase family 9C, member 3
Catalyzes the conversion of cortisol to the inactive metabolite cortisone. Modulates intracellular glucocorticoid levels, thus protecting the nonselective mineralocorticoid receptor from occupation by glucocorticoids.
Found in placenta, kidney, pancreas, prostate, ovary, small intestine and colon.
Defects in HSD11B2 are the cause of apparent mineralocorticoid excess (AME) [MIM:218030]. AME is a potentially fatal disease characterized by severe juvenile low-renin hypertension, sodium retention, hypokalemia and low levels of aldosterone. It often leads to nephrocalcinosis.
Belongs to the short-chain dehydrogenases/reductases (SDR) family.
