Abstract excerpt
Molecular genetic studies of attention deficit hyperactivity disorder (ADHD) have implicated the variable number of tandem repeat (VNTR) polymorphisms of two candidate genes, the dopamine D4 receptor (DRD4) and the dopamine transporter (DAT1). We sought to determine if these genes were relevant to the etiology of ADHD in China by using both family-based (N = 202 nuclear ADHD families) and case-control (N = 340...
