For the endocrine parameters, there were significant differences in the level of FSH among the PCOS patients carrying different genotypes of the two polymorphisms (p = 0.027 for Ser680Asn; p = 0.009 for Ala307Thr) and in the level of PRL among the PCOS patients carrying different genotypes of the Ser680Asn polymorphisms (p = 0.009) (Table 5). The gene discussed is BRD2; the disease is polycystic ovary syndrome.
