3β-Hydroxysteroid dehydrogenase/Δ isomerase (3β-HSD) (EC 1.1.1.145) is an enzyme that catalyzes the biosynthesis of the steroid progesterone from pregnenolone, 17α-hydroxyprogesterone from 17α-hydroxypregnenolone, and androstenedione from dehydroepiandrosterone (DHEA) in the adrenal gland. It is the only enzyme in the adrenal pathway of corticosteroid synthesis that is not a member of the cytochrome P450 family. It is also present in other steroid-producing tissues, inclu.Definition.

3-beta–hydroxysteroid dehydrogenase (3BHSD) deficiency is a rare genetic disorder of steroid biosynthesis that results in decreased production of all 3 groups of adrenal .Congenital Adrenal Hyperplasia due to 3-Beta-Hydroxysteroid Dehydrogenase-2 Deficiency. In 3 patients with classic 3-beta-HSD deficiency from 2 apparently unrelated pedigrees, Rheaume et al. (1992) described the nucleotide sequence of 2 highly homologous genes encoding 3-beta-HSD isoenzymes, types I (HSD3B1; 109715) and II (HSD3B2).No mutation . Introduction. Congenital adrenal hyperplasia (CAH) is a group of disorders caused by deficiency of one of five enzymes that are responsible for making cortisol from cholesterol in the adrenal glands [1–3]. 21-hydroxylase deficiency (21OHD) is the most common disorder causing CAH (95-99%) followed by 11-beta-hydroxylase deficiency (11OHD) [2, 4–7].
Classic 3-beta-hydroxysteroid dehydrogenase deficiency is an autosomal recessive form of CAH characterized by a severe impairment of steroid biosynthesis in both the adrenals and the gonads, resulting in decreased excretion of cortisol and aldosterone and of progesterone, androgens, and estrogens by these tissues. 3-beta–hydroxysteroid dehydrogenase (3BHSD) deficiency is a rare genetic disorder of steroid biosynthesis that results in decreased production of all 3 groups of adrenal steroids, which include mineralocorticoids, glucocorticoids, and sex steroids. Decreased mineralocorticoid secretion results in varying degrees of salt wasting in both males .

3β-hydroxysteroid dehydrogenase II (3β-HSD) deficiency represents a rare CAH variant. Newborns affected with its classic form have salt wasting in early infancy and genital ambiguity in both sexes. High levels of 17-hydroxypregnenolone (Δ517OHP) are characteristic, but extra-adrenal conversion to 17 .3 beta hsd deficiency 3β17-beta hydroxysteroid dehydrogenase 3 deficiency is a condition that affects male sexual development. People with this condition are genetically male, with one X and one Y chromosome in each cell, and they have male gonads ().Their bodies, however, do not produce enough of a male sex hormone (androgen) called testosterone.3-beta-hydroxysteroid dehydrogenase deficiency Description 3-beta (β)-hydroxysteroid dehydrogenase (HSD) deficiency is an inherited disorder that affects hormone-producing glands including the gonads (ovaries in females and testes in males) and the adrenal glands. The gonads direct sexual development before birth and during puberty.e diagnosis of NC3β-HSD in children. Adult women usually present with signs of androgen excess such as hirsutism, acne, temporal balding, irregular menses, and infertility. Among 759 women with signs of androgen excess reviewed in the literature, the prevalence for NC3β-HSD was 15.9%. The diagnosis of NC3β-HSD relies upon elevated Δ5 over Δ4-steroid ratios either after .The delta-5 steroid abnormality for the nonclassic 3 beta-HSD deficiency CAH, proven by genotype study, is substantially greater than the hormonal criteria for the disorder published before the advent of molecular information on the gene encoding adrenals and gonads in humans. In hyperandrogenic children and women, the pathogenic mechanism of a . All 3β-HSD members except type 4 possess these irreversible dehydrogenase and isomerase activities. Isolation of the cDNA and the transient in vitro expression of the human type I (3β-HSD1) and II (3β-HSD2) isoenzymes have confirmed that 3β-HSD and Δ 5 –Δ 4-isomerization activities reside within a single protein [5], [6], [7].However, data obtained from . Welzel et al. (2008) described the functional consequences of 3 C-terminal mutations in the 3-beta-HSD protein that were found in 4 patients with the classic form of beta-3-HSD deficiency with varying degrees of undervirilization. One of these was a missense mutation (P341L; 613890.0011) and the other 2 were nonsense mutations.
Congenital adrenal hyperplasia due to 3β-hydroxysteroid dehydrogenase/Δ 5-Δ 4-isomerase (3βHSD), a rare autosomal recessive disorder that affects both sexes, has a heterogeneous clinical presentation ranging from the severe salt-wasting to the non-salt-wasting forms and results from mutations in the HSD3B2 gene.The hormonal criteria for diagnosing the .
Human 3 beta-hydroxysteroid dehydrogenase deficiency (3b-HSD) is a very rare form of congenital adrenal hyperplasia resulting from HSD3B2 gene mutations. The estimated prevalence is less than 1/1,000,000 at birth. It leads to steroidogenesis impairment in both adrenals and gonads. Few data are available concerning adult testicular function in such patients. We had .

1. Introduction. Congenital adrenal hyperplasia (CAH) represents a group of disorders affecting adrenal and extra-adrenal steroidogenesis, caused by a deficiency in at least one of the enzymes involved in the synthesis of cortisol from cholesterol at the level of the adrenal cortex [1,2,3].The 21-hydroxylase (21OH) deficiency underling CYP21A2 gene mutations on .
To date, several cases of 3β-HSD deficiency diagnosed in childhood have been reported, but the relationship between prognosis and variable clinical characteristics is relatively under-explored. Therefore, we performed a systematic review of cases of 3β-HSD deficiency, aiming to find the potential factors that affect the prognosis.
Context: The clinical effects of classical 3β-hydroxysteroid dehydrogenase 2 (3βHSD2) deficiency are insufficiently defined due to a limited number of published cases. Objective: To evaluate an integrated steroid metabolome and the short- and long-term clinical features of 3βHSD2 deficiency. Design: Multicenter, cross-sectional study.
