Cortisol 11-beta-ketoreductase

The enzyme encoded by this gene metabolises cortisol to cortisone in the kidney and thereby prevents excessive mineralocorticoid receptor stimulation by cortisol. Deficiency results in clinical symptoms similar to hyperaldosteronism, which is remediable by dexamethasone suppressing cortisol secretion.
