Summaries for HSD3B2 Gene

Entrez Gene Summary for HSD3B2 Gene

  • The protein encoded by this gene is a bifunctional enzyme that catalyzes the oxidative conversion of delta(5)-ene-3-beta-hydroxy steroid, and the oxidative conversion of ketosteroids. It plays a crucial role in the biosynthesis of all classes of hormonal steroids. This gene is predominantly expressed in the adrenals and the gonads. Mutations in this gene are associated with 3-beta-hydroxysteroid dehydrogenase, type II, deficiency. Alternatively spliced transcript variants have been found for this gene.

Disorders for HSD3B2 Gene

(1) OMIM Diseases for HSD3B2 Gene (613890)


  • Adrenal hyperplasia 2 (AH2) [MIM:201810]: A form of congenital adrenal hyperplasia, a common recessive disease due to defective synthesis of cortisol. Congenital adrenal hyperplasia is characterized by androgen excess leading to ambiguous genitalia in affected females, rapid somatic growth during childhood in both sexes with premature closure of the epiphyses and short adult stature. Four clinical types: salt wasting (SW, the most severe type), simple virilizing (SV, less severely affected patients), with normal aldosterone biosynthesis, non-classic form or late-onset (NC or LOAH)and cryptic (asymptomatic). In AH2, virilization is much less marked or does not occur. AH2 is frequently lethal in early life. {ECO:0000269 PubMed:10599696, ECO:0000269 PubMed:10651755, ECO:0000269 PubMed:10843183, ECO:0000269 PubMed:12050213, ECO:0000269 PubMed:18252794, ECO:0000269 PubMed:22579964, ECO:0000269 PubMed:7608265, ECO:0000269 PubMed:7633426, ECO:0000269 PubMed:7633460, ECO:0000269 PubMed:7833923, ECO:0000269 PubMed:7893703, ECO:0000269 PubMed:7962268, ECO:0000269 PubMed:8060486, ECO:0000269 PubMed:8126127, ECO:0000269 PubMed:8185809, ECO:0000269 PubMed:8316254, ECO:0000269 PubMed:9719627}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Note=Mild HSD3B2 deficiency in hyperandrogenic females is associated with characteristic traits of polycystic ovary syndrome, such as insulin resistance and luteinizing hormone hypersecretion. {ECO:0000269 PubMed:14764797}.
