We identified novel differentially expressed genes (PRKAG2, MAPK1), and genes with known associations to either ADHD or ND (ANK3, CALD1, CHRNA4, CHRNA7, CMTM8, DLG4, DUSP6, GNG3, GNG11, GRIK5, GRINA2, GRM5, ICAM2, KCNJ6, PRKAB1, SNAP25, SYNPO, SYT1, VAMP2). Here, DUSP6 is linked to attention deficit-hyperactivity disorder.
