Overview

Non-classic CAH is one of the more common inherited conditions. Symptoms often appear in childhood, adolescence or adulthood and can be similar to polycystic ovary syndrome.

Symptoms

  • Early pubic hair in children
  • Fast growth and early bone maturation
  • Acne
  • Excess facial or body hair in women
  • Irregular periods and difficulty getting pregnant
  • Often no symptoms in men

Causes and risk factors

It is caused by a partial deficiency of an enzyme (21-hydroxylase) inherited from both parents.

Diagnosis

Diagnosis uses blood tests for 17-hydroxyprogesterone, sometimes after an ACTH stimulation test, and genetic testing.

Treatment

Treatment depends on symptoms and may include low-dose steroids, oral contraceptives, anti-androgen medicines and fertility support.

When to see a doctor

See a doctor if a child develops early signs of puberty or a woman has excess hair growth and irregular periods.
