Answer

Classic adrenal hyperplasia has an overall prevalence of 1 case per 16,000 population; however, in selected populations (eg, the Yupik of Alaska), the prevalence is as high as 1 case in 400 population. Congenital adrenal hyperplasia caused by 11-beta-hydroxylase deficiency accounts for 5-8% of all congenital adrenal hyperplasia cases.
