In addition to these, some other genes have also been found to be the cause of PCOS, i.e., plasminogen activator inhibitor-1 gene (PAI-1), apoprotein E (ApoE), resistin (RETN), glycogen synthetase (GYS1), paraoxonase (PON), aldosterone synthetase (CYP11B2), dopamine receptor (DRD), 17α-hydroxysteroid dehydrogenase (HSD), and 3-β-hydroxysteroid dehydrogenase (HSD3B2) genes [33,38,45,46,47,48,49,50,51,52]. The gene discussed is SERPINE1; the disease is polycystic ovary syndrome.
