Congenital adrenal hyperplasia due to steroid 21-hydroxylase deficiency (21OHD) is the commonest inborn error in steroid biosynthesis. It is caused by mutations in the 21-hydroxylase gene (CYP21A2). A good genotype–phenotype correlation exists allowing for prediction of the expressed adrenal phenotype. We performed functional and structural analysis of six novel CYP21A2 variants (p.Trp22Cys; p.Asp184Asn; p.Leu198Phe; p.Val305Gly; p.His310Asn; p.Thr443Asn), i...
