Abstract excerpt

Genetic polymorphisms in the human dopamine D4 receptor (DRD4) gene, especially the exon 3 variable number of tandem repeats (VNTR), have been related to several psychiatric disorders and personality traits. A homologous exon 3 VNTR has been described in dogs, and we previously showed an association between the DRD4 exon 3 polymorphism and activity/impulsivity trait in German shepherds. In this study, we present...
