The outcome of two pregnancies in a patient with Gitelman syndrome: case report and review of the literature.

We report a case of a 30-year-old woman who was first found to have a persistently low serum potassium level at 26 years of age during her first pregnancy. Genetic test of SLC12A3 confirmed Gitelman syndrome. The patient remained asymptomatic and had two deliveries following spontaneous labor. The first neonate died of heart failure due to cardiac abnormalities. The obstetric and neonatal outcome of the second pregnancy was good.
