Abstract

Objectives: Congenital adrenal hyperplasia (CAH) is a group of autosomal recessive diseases characterized by salt wasting or virilization. 21 hydroxylase deficiency (21-OHD) accounts for 90-95% of all cases of CAH and caused by the genetic defects of CYP21A2. Other forms include 3-beta-hydroxysteroid dehydrogenase deficiency, 11-beta-hydroxylase deficiency (11 beta-OHD) (%5-8), 17-alpha-hydroxylase deficiency (17 alpha-OHD), and steroidogenic acute regulatory protein (STAR) defects (congenital lipoid adrenal hyperplasia) with mutations in HSD3B2, CYP11B1, CYP17A1, and STAR, respectively. Objectives: Herein, we aimed to present the clinical and genetic features of 64 patients with various types of CAH.
