Overview
Epidemiology and Demographics
The classic type affects approximately 1 in 16,000 live births.2
NCCAH is one of the most common autosomal recessive disorders in humans and affects approximately 1 in 1000 individuals.3
The second most common form of CAH, 11b-hydroxylase deficiency (11-OHD), occurs in 1 in 100,000 live births in the general population and accounts for approximately 5% of cases.4
Other less common forms of CAH include 3b-hydroxysteroid dehydrogenase type 2 deficiency, 17a-hydroxylase deficiency that is more commonly seen in Brazil and Mennonite descendants from Dutch Friesland; congenital lipoid adrenal hyperplasia that is more commonly seen in the Japanese and Korean populations; side-chain cleavage (SCC) enzyme deficiency that is most commonly found in Turkey; and cytochrome P450 oxidoreductase deficiency, the only variant that can manifest with skeletal malformation
