Individuals with recently diagnosed diabetes from the All New Diabetics In Scania (ANDIS) study were grouped by phenotypic similarity based on six clinical variables selected to reflect important risk factors and aspects of the pathogenesis of diabetes: presence of GAD65 autoantibodies, age at diabetes diagnosis, BMI, HbA1c at diagnosis, and homeostatic model assessment estimates of insulin secretion capacity (HOMA2-B) and insulin resistance (HOMA2-IR). The gene discussed is GAD2; the disease is diabetes mellitus.
