DRD4 promoter SNPs and gender effects on Extraversion in African Americans.

Molecular psychiatry - 1 Jan 2002

Bookman E B, Taylor R E, Adams-Campbell L, Kittles R A

Abstract excerpt

There is strong evidence for genetic influences on personality traits. Interest in one such gene, the dopamine D4 receptor (DRD4) grew after an exon III polymorphism was associated with Novelty Seeking and related measures of Extraversion. However, the findings were not confirmed in later studies. Recently, a -521C/T single nucleotide polymorphism (SNP) within the promoter region of the DRD4 gene was found to be...
