17β-Hydroxysteroid dehydrogenase 2 (17β-HSD2) is an enzyme of the 17β-hydroxysteroid dehydrogenase (17β-HSD) family that in humans is encoded by the HSD17B2 gene.[5][6][7]


17β-HSD2 is involved in inactivation of androgens and estrogens,[8] being accurately describable as "antiandrogenic" and "antiestrogenic",[9] and is the key 17β-HSD isozyme in androgen and estrogen inactivation.[8] Specific reactions catalyzed by 17β-HSD2 include estradiol to estrone, testosterone to androstenedione, and androstenediol to DHEA.[8][10] In addition to 17β-HSD activity, this enzyme also shows high 20α-hydroxysteroid dehydrogenase activity and can activate the weak progestogen 20α-hydroxyprogesterone into the potent progestogen progesterone.[8][10]


17β-HSD2 is widely expressed throughout the body including in the placenta, liver, intestines, endometrium, kidney, pancreas, breast, prostate, bone, and many other tissues.[11][12]

Clinical significance

Polymorphisms in HSD17B2 have been associated with breast cancer and prostate cancer.[13] 17β-HSD2 activity has also been associated with endometriosis and osteoporosis,[14] and inhibitors of the enzyme are of potential interest in the treatment of the latter condition.[15][16] Inactivating mutations resulting in a syndrome of congenital deficiency of 17β-HSD2 have not been reported to date.[17]

PMID 16413960. 17β-HSD types 1–3, the key enzymes in homeostasis of steroid hormones (Andersson, 1995, Blomquist, 1995) seem to have their role solely in steroid metabolism catalysing reactions on steroid substrates only. [...] 17β-HSD2, an enzyme with broad tissue distribution (Casey et al., 1994), plays its major role in the inactivation of potent steroid hormones oxidising estradiol and testosterone to estrone and androstenedione, respectively (Wu et al., 1993). Beside this, 17β-oxidation of intermediates of steroid metabolism, e.g. 5α-androstane-3α,17β-diol, dihydrotestosterone and Δ5-androstene-3β,17β-diol is described (for review see Mindnich et al. (2004b). Additionally, human 17β-HSD type 2 has high 20α-HSD activity with progestins (Puranen et al., 1999).
