In 2018, Ahlqvist et al. performed a cluster analysis of patients with recently diagnosed diabetes (n = 8980) that were grouped by phenotypic similarity according to six clinical parameters: presence of glutamic acid decarboxylase (GAD) autoantibodies, age at diagnosis, glycated hemoglobin (HbA1c), body mass index (BMI), and homeostatic model assessment estimates of insulin secretion capacity (HOMA2-B) and insulin resistance (HOMA2-IR) [5]. The gene discussed is INS; the disease is diabetes mellitus.
