Insulin sensitivity indices [homeostatic model assessment (HOMA) of insulin resistance (HOMA-IR), whole body insulin sensitivity index (WBISI)] and β-cell function indices [HOMA of β-cell function (HOMA-β), insulinogenic index (IGI), and disposition index (DI)] were calculated from glucose and insulin levels obtained during the OGTT. The gene discussed is INS; the disease is Insulin resistance.
