Individual GAD primary gene sets were analyzed using Venny [14] http://bioinfogp.cnb.csic.es/tools/venny/index. html. Pathway Venn Diagram comparisons were performed by placing individual GAD primary gene sets into WebGestalt [15] http://bioinfo.vanderbilt.edu/webgestalt/ to identify KEGG pathways, then placing the resulting pathway names into Venny.
