Overview
Classification
Congenital adrenal hyperplasia may be classified in to seven different types, based on specified genetic mutation as following:[1]
- 21-hydroxylase deficiency
- Genetic defects: CYP21A2
- The most common cause of congenital adrenal hyperplasia worldwide, accounting for more than 90 percent of cases, is 21-hydroxylase deficiency.[2]
- 11β-hydroxylase deficiency
- Genetic defect: CYP11B1
- 17α-hydroxylase/ 17,20-lyase deficiency
- Genetic defect: CYP17A1
- 3β-hydroxy-steroid dehydrogenase type 2 deficiency
- Genetic defect: HSD3B2
- P450 oxidoreductase deficiency
- Genetic defect: POR
- Lipoid adrenal hyperplasia
- Genetic defect: StAR
- Cholesterol side chain cleavage enzyme deficiency
- Genetic defect: CYP11A1
