TL;DR
The present study did not yield evidence for an association between Extraversion and the dopamine receptor D4 polymorphism.
Abstract
An association between long alleles of a variable number tandem repeat (VNTR) polymorphism in the dopamine receptor D4 gene and the extraversion related personality traits Excitement and Novelty Seeking has been reported in healthy subjects. In an attempt to replicate the previous findings, 256 healthy Caucasian volunteers were analysed for a potential relationship between the dopamine receptor D4 exon III VNTR polymorphism and Extraversion as assessed by the Revised Neo Personality Inventory (NEO PI-R). The present study did not yield evidence for an association between Extraversion and the dopamine receptor D4 polymorphism.

It is concluded that the most likely explanation of these results is that the DRD4 VNTR does not influence directly the trait of novelty seeking, in these samples.

The results provide further confirmation for the role of the DRD4 exon III polymorphism in modulation of Novelty Seeking, and the pattern of associations between the polymorphism and other scales suggests that this polymorphism has its effect on exploratory, extravagant, and extraverted, rather than on impulsive and monotony-avoidant subtypes of novelty Seeking.

The results confirm the original findings of an association between the type 4 dopamine receptor (DRD4) gene and novelty seeking, while showing that novelty seeking is probably not influenced by the polymorphism itself but, rather, a different DNA variant in the DRD4 gene or another gene in linkage disequilibrium with it.

There were no significant associations between long alleles (7-repeat allele) and high novelty seeking groups and future research must carefully address whether the D4DR genetic polymorphisms vary substantially across demographic groups.
