Chimeric CYP11B2/CYP11B1 causing 11?-hydroxylase deficiency in Chinese patients with congenital adrenal hyperplasia..     ///    "A chimeric CYP11B1/CYP11B2 gene causes glucocorticoid-remediable aldosteronism (GRA), while the rare CYP11B2/CYP11B1 chimeric gene leads to 11?-hydroxylase deficiency (11-OHD). "    ///    "We found that patient 1 and patient 2 harbored novel homozygotic chimeric CYP11B2/CYP11B1 genes consisting of the promoter, exons 1-6 of CYP11B2, and exons 7-9 of CYP11B1. "    ///    Rare chimeric CYP11B2/CYP11B1 gene mutations are the underlying cause of disease in three patients with 11-OHD.     ///    The breakpoints to form Chimeric CYP11B2/CYP11B1 were not the same for the three patients.
