21-Deoxycortisol, also known as 11β,17α-dihydroxyprogesterone or as 11β,17α-dihydroxypregn-4-ene-3,20-dione, is a naturally occurring, endogenous steroid related to cortisol (11β,17α,21-trihydroxyprogesterone) which is formed as a metabolite from 17α-hydroxyprogesterone via 11β-hydroxylase.[1]

Marker of 21-hydroxylase deficiency

21-deoxycortisol is a marker of congenital adrenal hyperplasia due to 21-hydroxylase deficiency,[2][1][3] even in mild (non-classic) cases.[4][5] It can be also used for newborn screening.[6]

The deficiency of the 21-hydroxylase enzyme leads to excess of 17α-hydroxyprogesterone,[7][8] a 21-carbon (C21) steroid. This excess is accompanied by the accumulation of other C21 steroids, such as 21-deoxycortisol, which is formed by the 11β-hydroxylation of 17α-hydroxyprogesterone[7] via 11β-hydroxylase (CYP11B1).[1] The build-up of 21-deoxycortisol in patients with congenital adrenal hyperplasia have been described since at least 1955, this steroid was then called "21-desoxyhydrocortisone".[9][10] Unlike 17α-hydroxyprogesterone, 21-deoxycortisol is not produced in the gonads and is uniquely adrenal-derived. Hence, 21-deoxycortisol is a more specific biomarker of 21-hydroxylase deficiency than is 17α-hydroxyprogesterone.[11]

The corticosteroid activity of 21-deoxycortisol is lower than that of cortisol.[12][13]

As 21-deoxycortisol can be at high levels in congenital adrenal hyperplasia, and it has structural similarity to cortisol, it can cross-react in immunoassays,[14][15][16] resulting in a falsely normal or high cortisol result, when the true cortisol is actually low. Whereas immunoassays can suffer from cross-reactivity due to interactions with structural analogues, the selectivity offered by liquid chromatography-tandem mass spectrometry (LC-MS/MS) has largely overcome these limitations.[17][18] Hence, the use of LC-MS/MS instead of immunoassays in cortisol measurement aims to provide greater specificity.[19]

Besides 21-deoxycortisol, another C21 steroid, 21-deoxycorticosterone (11β-hydroxyprogesterone), has been proposed as a marker for 21-hydroxylase deficiency,[20][21][22] but this marker did not gain acceptance due to the fact that testing for the levels of this steroid is not routinely offered by diagnostic laboratories.[23]
