Bartter syndrome

From SNPedia

Bartter syndrome is a rare inherited kidney disorder in the thick ascending limb of the loop of Henle. It is characterized by low potassium levels (hypokalemia), increased blood pH (alkalosis), and normal to low blood pressure. There are two types of Bartter syndrome: neonatal and classic. A closely associated disorder, Gitelman syndrome, is milder than both subtypes of Bartter syndrome.Wikipedia

Bartter and Gitelman syndromes can be divided into different subtypes based on the genes involved 10.1159/000076752:
