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. Immun...

Background: Haplo-insufficiency of the Myelin-Regulatory Factor (MYRF) gene causes cardiac-urogenital syndrome (CUGS) and Differences in Sexual Development (DSD) in 46,XY and 46,XX (OMIM #618280). The gene product, a transcription factor, is involved in development of Coelomic epithelium derived cells, and likely causative for DSD. To date, only a few MYRF de novo variants are reported in children with DSD and associated CUGS symptoms.<s...

Background: Prenatal dexamethasone treatment (Pdex) has been used since the 1980s to prevent virilization in female offspring suspected to have congenital adrenal hyperplasia (CAH). However, due to lack of strong evidence for its best practice as well as limited data regarding long term adverse effects, use of dex is highly controversial. This study reveals the current medical practice regarding Pdex in female fetuses at risk of CAH due to 21 hydroxylase defic...
