A significant positive correlation was found between galectin-9 level and body fat (r = 0.4070, P = 0.0435), waistline (r = 0.4025, P = 0.0461), CRP (r = 0.5918, P = 0.0018), and HbA1c (r = 0.6037, P = 0.0014) in obesity patients, but there were no significant correlations between galectin-9 and BMI, LDL, HDL, and TG (Figure 3, Table 2). Here, LGALS9 is linked to obesity due to melanocortin 4 receptor deficiency.
