17β-Hydroxysteroid Dehydrogenase Type 3 Deficiency: Diagnosis, Phenotypic Variability and Molecular Findings
The steroid hormones are lipophilic compounds with low molecular weight, derived from cholesterol, which play a crucial role in differentiation, development and physiological functions of many tissues. They are synthesized primarily by endocrine glands, such as the gonads, the adrenal glands and the feto-placental unit during pregnancy. In addition, the central nervous system (CNS) seems to be ...
متن کاملSynthesis and Molecular Docking Studies of 2-arylideneindan-1,3-diones Derivatives as an Inhibitor of 17β-hydroxysteroid Dehydrogenase Type 1
Due to the drawbacks of applying catalysts in the synthesis of α,β-unsaturated structure units and the importance of these materials, electrochemistry has been introduced as an efficient alternative.Therefore, herein a high-yield synthesis of 2-arylideneindan-1,3-diones is proposed. The procedure is carried out in propanol, using electrons as a green catalyst for generating propanol anion...
متن کاملSevere Undervirilisation in a 46,XY Case Due to a Novel Mutation in HSD17B3 Gene
17-β-hydroxysteroid dehydrogenase type 3 (17β-HSD3) is an important enzyme involved in the final steps of androgen synthesis and is required for the development of normal male external genitalia. 46,XY individuals with deficiency of this enzyme present a wide clinical spectrum from a female appearance of the external genitalia through ambiguous genitalia to a predominantly male genitalia with m...
متن کاملMolecular genetics and pathophysiology of 17 beta-hydroxysteroid dehydrogenase 3 deficiency.
Autosomal recessive mutations in the 17 beta-hydroxysteroid dehydrogenase 3 gene impair the formation of testosterone in the fetal testis and give rise to genetic males with female external genitalia. Such individuals are usually raised as females, but virilize at the time of expected puberty as the result of increases in serum testosterone. Here we describe mutations in 12 additional subjects/...
متن کاملClinical and molecular characterization of patients with classic 3β-hydroxysteroid dehydrogenase deficiency
Background 3b-hydroxysteroid dehydrogenase type 2 (3bHSD2) is the key enzyme converting Δ5-steroids to Δ4-ketosteroids in adrenal and gonadal steroidogenesis. Severe lossof-function mutations of HSD3B2 gene encoding for this enzyme cause the rare form of congenital adrenal hyperplasia, “3bHSD deficiency”. Affected individuals have salt losing, adrenal insufficiency and ambiguous genitalia in bo...
