Background: Congenital adrenal hyperplasia due to 21-hydroxylase deficiency (CAH) is associated with ACTH-driven adrenal androgen excess. In women with classic CAH, this regularly causes prenatal virilisation of the external genitalia, commonly corrected by genital surgery during the first years of life. This practice, however, has been questioned and is discussed highly controversial. The aim of this study was to retrospectively assess the perspective of affected patients and...

Congenital adrenal hyperplasia due to 21-hydroxylase deficiency (CAH) is encoded by the CYP21A2 gene. The CYP21A2 gene is partially overlapped by the TNXB gene encoding an extracellular matrix protein called Tenascin-X. Deficiency of Tenascin X can cause the Ehlers-Danlos Syndrome (EDS). Deletions of CYP21A2 extending into TNXB rarely cause CAH combined with EDS. CAH associated with mild hypermobility form of EDS due to TNXB haploinsufficiency caused by heterozygous mutation h...
