== Disease ==
[https://www.uniprot.org/uniprot/DHI1_HUMAN DHI1_HUMAN] Defects in HSD11B1 are a cause of cortisone reductase deficiency (CRD) [MIM:[https://omim.org/entry/604931 604931]. In CRD, activation of cortisone to cortisol does not occur, resulting in adrenocorticotropin-mediated androgen excess and a phenotype resembling polycystic ovary syndrome (PCOS).
== Function ==
[https://www.uniprot.org/uniprot/DHI1_HUMAN DHI1_HUMAN] Catalyzes reversibly the conversion of cortisol to the inactive metabolite cortisone. Catalyzes reversibly the conversion of 7-ketocholesterol to 7-beta-hydroxycholesterol. In intact cells, the reaction runs only in one direction, from 7-ketocholesterol to 7-beta-hydroxycholesterol (By similarity).
