WebDeficient P450c11β activity causes about 5% of CAH in persons of European ancestry but is more common in both Moslem and Jewish Middle Eastern populations. 127,128 Severe deficiency of P450c11β decreases the secretion of cortisol, causing CAH and virilization of affected females. Congenital adrenal hyperplasia (CAH) refers to any of several autosomal recessive diseases resulting from defects in steps of the synthesis of cortisol from cholesterol by the adrenal glands. All of the forms of CAH involve excessive or defective production of sex steroids and can prevent or impair development of primary or secondary sex characteristics in affected infants, children, and adults. Many also involve excessive or defective production of mineralocorticoids, which can cause the outgoing administration

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. WebThe substrate for P450c11 is 11-deoxycortisol. Mutations in CYP11B1 cause congenital adrenal hyperplasia (CAH) due to 11beta-hydroxylase deficiency. This disorder is characterized by androgen excess and hypertension and is autosomal recessively inherited. Classical and nonclassical forms of 11beta-hydroxylase deficiency can be distinguished.

WebThe increase in the powerful mineralocorticoid deoxycorticosterone, resulting from the enzymatic block, promotes sodium retention, hypertension, and hypokalemia.
