Hyperinsulinemia (>20 μU/L) was associated with significant reduction in albumin (2.67 ± 0.59 vs. 3.56 ± 0.37 g/dL; p = 0.0001), albumin/globulin ratio (0.57 ± 0.24 vs. 1.01 ± 0.32 g/dL; p = 0.0001), catalase (17.23 ± 2.24 vs. 100.67 ± 30.99 U/mL; p = 0.021), NO (19.23 ± 2.24 vs. 21.35 ± 1.29 mmoL/mL; p = 0.002), glucose (5.44 ± 0.53 vs. 5.61 ± 0.38 mmol/L; p = 0.038), and glucose/insulin ratio (0.18 ± 0.04 vs. 0.72 ± 0.41; p = 0.0001). The gene discussed is INS; the disease is hyperinsulinism.
