- 21-Deoxycortisol is a steroid hormone metabolite that serves as a critical biomarker in the differential diagnosis of congenital adrenal hyperplasia (CAH), particularly the 11-beta-hydroxylase deficiency form. This compound, while less commonly discussed than cortisol itself, plays an essential role in understanding adrenal steroidogenesis and identifying specific enzymatic defects within the cortisol synthesis pathway.
