Furthermore, in a recent cross-disorder study investigating the genetic architecture of eleven psychiatric disorders, including attention-deficit/hyperactivity disorder (ADHD), ASD, anxiety disorders, bipolar disorder, major depressive disorder (MDD), obsessive–compulsive disorder (OCD), and SCZ, among others, RBFOX1 emerged as an independent associated locus in genome-wide association study (GWAS) across all eleven psychiatric traits [9]. Here, RBFOX1 is linked to attention deficit-hyperactivity disorder.
