Overview

Patients with 21-hydroxylase deficiency usually appear underweight and dehydrated. Physical examination is usually remarkable for hypotension and virilization.

Physical Examination

Common physical examination findings of 21-hydroxylase deficiency include:^[1]^[2]^[3]^[4]^[5]

Reflex tachycardia

Head

Hirsutism

Female in non-classic type may have:
- Clitoromegaly
Male in classic type may have:
- Penile enlargement
- Testicular mass
- Hyperpigmentation of the scrotum
- Early virilization at two to four years of age with pubic hair growth, growth spurt, adult body odor

- Normal appearing at birth.

Cognitive function:

Female:
- Male-typical cognitive pattern (better performance on spatial tasks, worse performance on verbal tasks)
- Cross-gender role behavior
- Lower intelligence quotients (IQ)
