The first aforementioned study also compared overweight/obese PCOS subjects (n = 40) to lean PCOS subjects (n = 32), and concluded that body mass excess may decrease myonectin concentration (6.34 ± 1.93 vs. 7.31 ± 1.90 ng/mL; p = 0.038) [27]. The gene discussed is ERFE; the disease is polycystic ovary syndrome.
