T1D candidate genes are highly expressed in endothelial, islet, and immune tissues. T1D risk loci were collected from ImmunoBase (http://www.immunobase.org), tissue expression was identified per tissue (genevisible.com/search), and a venn diagram was created based on relative abundance of expression in immune (blue), endothelial (purple), and pancreatic islet tissue (green) 61.
