Multiple neoplasia in a patient with Gitelman syndrome harboring germline monoallelic MUTYH mutation

Gitelman syndrome is a rare, recessively inherited disease characterized by chronic hypokalemia and hypomagnesemia as a result of defective electrolyte co-transport at the level of the distal convoluted tubule of the kidney. Here, we present the first report of a patient with Gitelman syndrome who d...
