Congenital Adrenal Hyperplasia: Congenital adrenal hyperplasia (CAH) is an autosomal recessive disease emerging from mutations of genes for enzymes that lead to the biochemical steps of production of glucocorticoids, mineralocorticoids, or sex steroids from cholesterol by the adrenal glands. Females with CAH might have genitalia that appear different from what is expected for girls, early puberty, deepening voice, short height, acne, excessive facial or body hair, or menstrual irregularities. Both males and females with CAH may have infertility or adrenal crisis.
