ALT exhibited significant positive correlations with fasting blood sugar (r=0.547, p<0.0001), HbA1C (r=0.281, p=0.001), total cholesterol (r=0.575, p<0.0001), triglycerides (r=0.610, p<0.0001), LDL (r=0.577, p<0.0001), and diabetes duration (r=0.188, p=0.012). This evidence concerns the gene GPT and diabetes mellitus.
