Several genes identified in DGE and pathway analysis are implicated in human ADHD and ND (ANK3, CALD1, CHRNA4, CHRNA7, CMTM8, DLG4, DUSP6, GNG3, GNG11, GRIK5, GRINA2, GRM5, ICAM2, KCNJ6, MAPK1, PRKAB1, PRKAG2, SNAP25, SYNPO, SYT1, VAMP2). Here, CHRNA4 is linked to attention deficit-hyperactivity disorder.
