21-Hydroxylase Deficiency

Overview

Type of disease: Rare conditions

21-hydroxylase-deficiency is a genetic disorder of cortisol biosynthesis. It is caused by mutations in the human 21-hydroxylase gene (CYP21A2).  Symptoms of 21-hydroxylase deficiency vary, but can involve salt-wasting crises in infants; ambiguous genitalia in female infants; excessive hair, deep voice, abnormal periods, no periods, and fertility problems in older girls and women; early development of masculine features in boys; and shorter than average adult height, acne, and blood pressure problems.
