Two Moroccan Sisters Presenting with a Severe Salt-Wasting Form of Congenital Adrenal Hyperplasia but Normal Female Genitalia.

We report the case of 2 sisters (46,XX) born from consanguineous Moroccan parents. Both sisters had normal female genitalia, but within 2 weeks after birth, they presented with a severe salt-wasting crisis. Hormonal investigations suggested the diagnosis of congenital adrenal hyperplasia, which was confirmed by subsequent molecular analysis to be caused by 3β-hydroxysteroid dehydrogenase type 2 deficiency. Here, we discuss the main features like onset, possible complications, genetics, and replacement therapy of this rare disease.
