== Disease ==
 +
[https://www.uniprot.org/uniprot/AK1D1_HUMAN AK1D1_HUMAN] Defects in AKR1D1 are the cause of congenital bile acid synthesis defect type 2 (CBAS2) [MIM:[https://omim.org/entry/235555 235555]; also known as cholestasis with delta(4)-3-oxosteroid 5-beta-reductase deficiency. Patients with this liver disease show absence or low levels of chenodeoxycholic acid and cholic acid in plasma and urine.<ref>PMID:12970144</ref> <ref>PMID:15030995</ref>
 +
== Function ==
 +
[https://www.uniprot.org/uniprot/AK1D1_HUMAN AK1D1_HUMAN] Efficiently catalyzes the reduction of progesterone, androstenedione, 17-alpha-hydroxyprogesterone and testosterone to 5-beta-reduced metabolites. The bile acid intermediates 7-alpha,12-alpha-dihydroxy-4-cholesten-3-one and 7-alpha-hydroxy-4-cholesten-3-one can also act as substrates.
