Web11 de fev. de 2024 · The gene CYP11B1 encodes 11β-hydroxylase that catalyzes the conversion of 11-deoxycortisol and 11-deoxycorticosterone to cortisol and corticosterone in the zona fasciculata. Thus, from a clinical perspective, deficiency of 11β-hydroxylase, results in low levels of cortisol and high levels of 11-deoxycortisol and 11-deoxycorticosterone … WebThe increase in the powerful mineralocorticoid deoxycorticosterone, resulting from the enzymatic block, promotes sodium retention, hypertension, and hypokalemia. Females who have the deficiency also show signs of virilization due to the shunting of the precursors to the synthesis of adrenal androgens.

WebResults: Our results showed that adrenal insufficiency of any cause was adequately diagnosed using the response of 11-deoxycortisol, dehydroepiandrosterone, or these analytes combined in a two-steroid profile. A three-steroid profile yielded a test with 100% accuracy for discriminating primary adrenal insufficiency from normal status.
