Classification

Congenital adrenal hyperplasia is classified into seven types based on the genetic causes that lead to hyperplasia and hormonal imbalance.

Disease History and symptoms Laboratory findings Defective gene
Blood pressure Genitalia K levels
21-hydroxylase deficiency Classic type
  • Low in salt-wasting
  • Normal in non-salt-wasting
  • Female: ambiguous
  • Male: normal or scrotal pigmentation and large phallus

Increased:

  • 17-OHP
  • Progesterone
  • Androstenedione
  • DHEA

Decreased:

  • Aldosterone
  • Corticosterone (salt-wasting)
  • Cortisol (simple virilizing)
  • High in salt wasting type
  • Normal in non salt wasting
Non-classic type
  • Normal
  • Female: virilization after puberty
  • Male: normal appearance
Increased:
  • 17-OHP
  • Exaggerated androstene-dione, DHEA, and 17-OHP

response to ACTH

  • Normal
17a-Hydroxylase deficiency
  • Hypertension
  • Increased DOC, corticosterone
  • Decreased 17OH-steroids, cortisol, aldosterone, androgens and estrogens
  • Low
CYP17A1
11β-hydroxylase deficiency
  • Hypertension
  • Female: ambiguous
  • Male: normal or scrotal pigmentation and large phallus
  • Indreased DOC, 11-deoxycortisol
  • Decreased corticosterone, cortisol, aldosterone, androgens
  • Low
CYP11B1
3-beta-hydroxysteroid dehydrogenase Increased:
  • DHEA
  • 17-OH pregneno-lone
  • Pregnenolone

Decreased:

  • Cortisol
  • Aldosterone
  • High
Cytochrome P450-oxidoreductase (POR) deficiency (ORD)
