IL17A and obesity due to melanocortin 4 receptor deficiency: Our study aligns with the findings of Garcia et al. (2021), which demonstrated that serum IL-17 levels were significantly higher in individuals with obesity (34.99 pg/mL), with positive correlations between IL-17 levels and both the BMI and waist circumference (OR of 0.413 and 0.337, respectively, both significant at p < 0.001) [29].
