The results of the first study conducted on PCOS genotypes in Pakistan suggest that the CYP 17 5′-UTR MspA1 (rs743572) (genotype TC) and CYP19 gene (rs2414096) (genotype GA) polymorphisms are significantly associated with the vulnerability to PCOS in Pakistani women with the traits of infertility and a family history of hypertension [157]. This evidence concerns the gene CYP19A1 and polycystic ovary syndrome.
