Successful pregnancy in a patient with severe 11-beta-hydroxylase deficiency and novel mutations in CYP11B1 gene

11 beta-Hydroxylase deficiency is a rare form of congenital adrenal hyperplasia, resulting in virilization, glucocorticoid deficiency and hypertension. There have been no previous reports in the literature of a successful pregnancy in a severely affected female. We report the first successful pregnancy resulting in a live birth for a female with 11 beta-hydroxylase deficiency and outline management issues from preconception to successful birth. We also report 2 novel mutations in the CYP11B1 gene leading to 11 beta-hydroxylase deficiency. Copyright (c) 2007 S. Karger AG, Basel.
