LEP and obesity due to melanocortin 4 receptor deficiency: When comparing the two groups, those with vs. those without obesity (Table 3), a significant difference in leptin levels in ng/mL (30.61 ± 18.60 vs. 4.14 ± 3.19; p < 0.001), adiponectin in μg/mL (29.54 ± 23.95 vs. 67.71 ± 41.63; p < 0.001), and GGT in U/L (21.86 ± 13.49 vs. 15.00 ± 2.69; p < 0.001) is observed.
