Hartanti, et al. (2020), Liu, et al. (2020) showed that all PCOS candidate genes in/near loci identified by GWAS, except small ubiquitin like modifier 1 pseudogene 1 (SUMO1P1), and three additional candidate genes AR, AMH and transforming growth factor beta 1 induced transcript 1 (TGFB1I1) were expressed in human and bovine fetal ovaries. Here, AMH is linked to polycystic ovary syndrome.
