Abstract

Tubulopathies are a heterogeneous group of entities defined by abnormalities of renal tubular function. Gitelman syndrome, the subject of our article, is caused by inactivating mutations of the SLC12A3 gene, which encodes the thiazide-sensitive Na-Cl cotransporter of the distal convoluted tubule, thus producing a urinary loss of Cl-Na.

Three clinical cases of Gitelman syndrome are presented, each with a clinical presentation. The purpose of this article is to familiarize the reader with this tubulopathy and to help in its early diagnosis.
