DNA methylation changes associated with type 1 diabetes were previously detected in individuals clinically diagnosed with the disease. Recently, using array-based methods, these changes were also detected in whole blood samples from individuals before they developed diabetes. In this issue, Starskaia et al ( use genome-wide reduced representation bisulphite sequencing to detect cell type-specific DNA methylation changes associated with type 1 diabetes before clinical diagnosis, and even before the appearance of autoantibodies. The authors conclude that the early epigenetic changes associated with type 1 diabetes identified in this study may contribute to pathogenesis and provide basis for the early detection of diabetes.
