Gitelman syndrome with diabetes and kidney stones: A case report

When unexplained hypokalemia is observed, the HCT test can help with the diagnosis of GS. When genetic testing reveals that a patient only carries only 1 SLC12A3 mutant allele, he requires further genetic evaluation. The patient's combination of kidney stones and cysts could not exclude the diagnosis of GS. Patients with GS and diabetes should be monitored for the development of diabetic ketoacidosis.
