In addition, haploinsufficiency for CNTNAP2, resulting from gene disruption, has been implicated in other clinically distinct behavioral disorders such as Gilles de la Tourette syndrome [40] (GTS; MIM 137580), attention-deficit/hyperactivity disorder [41] (ADHD) and, schizophrenia and epilepsy [42]. The gene discussed is CNTNAP2; the disease is attention deficit-hyperactivity disorder.
