Congenital adrenal hyperplasia (CAH) is due to defective adrenal cortisol biosynthesis. In most cases, deficiency of a P 450-C21 specific steroid hydroxylase impairing cortisol synthesis has been found. The disease is HLA-linked, and on clinical grounds it can be divided into two major forms, the classical and the non-classical type. Here, evidence is presented that the classical and the non-classical forms of CAH caused by 21-OH deficiency are due to different genetic alterations in the C4/21-OH gene region. In most cases of classical CAH associated with the HLA-Bw47 antigen, a specific and selective loss of the 21-OH B gene was observed with some interesting exceptions. Alterations in the 21-OH gene region in the non-classical forms of CAH, patients either HLA-B14; DR1 homo- or heterozygous, are different. Our data indicate the possibility of gene conversion events in this genomic region in non-classical CAH.
