Overview

Classification

Congenital adrenal hyperplasia may be classified in to nine 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 defects: CYP11B1
  • 17α-hydroxylase/ 17,20-lyase deficiency
    • genetic defects: CYP17A1
  • 3β-hydroxy-steroid dehydrogenase type 2 deficiency
    • genetic defects: HSD3B2
  • P450 oxidoreductase deficiency
    • genetic defects: POR
  • Lipoid adrenal hyperplasia
    • genetic defects: StAR
  • Cholesterol side chain cleavage enzyme deficiency
    • genetic defects: CYP11A1
