A previously undescribed mutation detected by sequence analysis of CYP21A2 gene in an infant with salt wasting congenital adrenal hyperplasia.

The Human Cytochrome P450 (CYP) Allele Nomenclature Committee (http:www.imm.Ki.se/CYPalleles/cyp21.htm) has created a CYP21A2 database which include a list of all reported CYP21A2 mutations and the last update of this database was in 2006. The most up to date list of the CYP21A2 mutations reported over the last four years was published in a recent article by Concolino et al. We report a previously undescribed mutation detected by sequence analysis of CYP21A2 gene in an infant resulting in salt wasting congenital adrenal hyperplasia.
