Introduction: 3-beta-hydroxysteroid dehydrogenase (HSD3B2) deficiency causes a rare form of Congenital Adrenal Hyperplasia (CAH) characterised by varying degrees of mineralocorticoid and glucocorticoid deficiencies with undermasculinisation in genetic males. The biochemical hallmarks are elevated androgen precursors in the delta5 pathway (dehydroepiandrosterone (DHEA) and 17-pregnenolone), with low mineralocorticoids and low (stimulated) cortisol levels.
