IL6 and obesity due to melanocortin 4 receptor deficiency: IL-10(−1082G > A),(− 819 T > C), (−592A > C), TGF-β(+ 869 T > C), (+915C > G) IL-6(−174G > C), TNF-α(−308G > A) and IL-18(−137G > C),(−607C > A) cytokine polymorphisms were not correlated with the examined factors (BMI/obesity, blood cholesterol, triglycerides, fasting plasma glucose, creatinine) and their variations along the considered period after transplantation (Supporting information Figure 7: cytokine polymorphism and BMI; other variables: not shown).
