One of the conducted toxicogenomic studies which assessed the link between PFAS mixtures and polycystic ovary syndrome (PCOS) found 74 genes linked to both PFAS exposure and PCOS, highlighting cell cycle regulation and steroid hormone synthesis—particularly genes like CCNB1 and SRD5A1 [30]. Here, CCNB1 is linked to polycystic ovary syndrome.
