In Choi et al.’s study [44], an increase in the level of CTRP3 in patients with DM type 2 was found; however, other studies showed a decrease of the discussed adipocytokine in patients with DM type 2 and/or obesity [13,15,41,42,43], which corresponds with the results obtained in this research paper. The gene discussed is C1QTNF3; the disease is obesity due to melanocortin 4 receptor deficiency.
