Behavioral genetic research has consistently revealed that genetic factors explain at least one half of the variance in measures of cognitive skills. However, the specific DNA markers involved in the etiology of cognitive abilities have remained elusive. The current study examined the association between the TaqI polymorphism in the dopamine D2 receptor gene (DRD2) and verbal skills. Analysis of data drawn from the National Longitudinal Study of Adolescent Health (Add Health) revealed that the A1 allele was associated with group membership in high-, average-, and low-verbal skills groups for Caucasians. The results suggest that DRD2 may be related to domain specific cognitive abilities, such as verbal skills.
