Recent genome-wide association studies have found susceptibility loci close to genes encoding FSH receptor (FSHR), FSH B polypeptide gene (FSHB), and LH choriogonadotropin receptor (LHCGR), implicating gonadotropins and their receptors in the pathogenesis of PCOS (9–11). The gene discussed is LHCGR; the disease is polycystic ovary syndrome.
