Significant (p < 0.05) but not strong correlations were observed between patients’ age and BMI z-score (r = 0.33), fasting insulin (r = 0.15), HOMA-IR (r = 0.17), QUICKI (r = −0.23), Matsuda index (r = −0.19), HDL (r = −0.16), and uric acid (r = 0.21), speaking for the increase in obesity, IR, and other metabolic disorders with age. The gene discussed is INS; the disease is obesity due to melanocortin 4 receptor deficiency.
