Background:
21-Deoxycortisone is a corticosteroid metabolite of 11-keto progesterone.1It is formed from 11-keto progesterone by the cytochrome P450 (CYP) isoform CYP17A1, but can also be producedviaoxidation of 21-deoxycortisol by 11β-hydroxysteroid dehydrogenase type 2 (11β-HSD2). Levels of 21-deoxycortisone are increased in patients with congenital adrenal hyperplasia, an inborn error of metabolism characterized by a deficiency in 21-hydroxylase.2
