In the multivariable linear regression analysis––after adjusting for group, age, sex, hypertension, coronary artery disease, BMI, fasting glucose, log-transformed triglycerides, total cholesterol, high-density lipoprotein–cholesterol, eGFR, GOT, GPT and a urinary albumin–creatinine ratio >30 mg/g––old age, and a high BMI were independently correlated with high fasting glucose for the relatives of a patient with type 2 diabetes (vs. controls; unstandardized coefficient β: 5.611; 95% confidence interval (CI), 1.282–9.940; p = 0.011). This evidence concerns the gene GPT and hypertensive disorder.
