Bartter syndrome is a group of rare renal tubular disease characterized by impaired salt reabsorption in the thick ascending limb of Henle's loop and clinically by the association of hypokalemic alkalosis, hypercalciuria/nephrocalcinosis, increased levels of plasma renin and aldosterone, low blood pressure and vascular resistance to angiotensin II. The disease is Bartter syndrome (MONDO_0015231). Also known as: Bartter disease, Bartter's syndrome, aldosteronism with hyperplasia of the adrenal cortex, hypokalemic alkalosis, renal tubular normotensive hypokalemic alkalosis with hypercalciuria, salt-losing tubular disorder, Henle's loop type, salt-wasting tubulopathy, Henle's loop type.
