Association of a Polymorphism of the Dopamine Transporter Gene With Externalizing Behavior Problems and Associated Temperament Traits: A Longitudinal Study From Infancy to the Mid-Teens

Abstract

There have been reports that a variable number of tandem repeats (VNTR) polymorphism situated in the 3′ untranslated region of the dopamine transporter gene is associated with attention-deficit hyperactivity disorder. On the basis of these findings, we
