Glintborg et al. observed that PRL was positively associated with HDL-C (r = −0.11, P < 0.05) and inversely associated with TC (r = −0.15, P < 0.05) and TG (r = −0.14, P < 0.05), with the inverse association between PRL and LDL-C (r = −0.15, P < 0.05) being independent of age and BMI in a cohort of polycystic ovary syndrome (PCOS) patients [19]. The gene discussed is PRL; the disease is polycystic ovary syndrome.
