Modeling hyperactivity: of mice and men

Although attention deficit hyperactivity disorder (ADHD) is a highly heritable and common psychiatric disorder, few susceptibility genes have been identified. A new multidisciplinary genetic study in humans and mice reveals GIT1 (encoding G protein–coupled receptor kinase–interacting protein-1) as a previously undescribed ADHD susceptibility gene in humans and provides new insights into the underlying mechanisms of this condition (pages 566–572).
