Abstract

This study was designed to assess the association between novelty seeking and D4DR gene polymorphism in the Japanese population. The 48 bp repeat polymorphism in the third exon of the dopamine D4 receptor gene of 153 normal female students was correlated with personality feature results from the Japanese version of Cloninger's Temperament and Character Inventory. The Novelty Seeking subscale of Exploratory Excitability had a significant association with long alleles of the polymorphic exon III repeat sequence of D4DR. Our results suggest that there is an association between long alleles of the polymorphic exon III repeat sequence of D4DR and the personality traits of the Novelty Seeking subscale of Exploratory Excitability, regardless of racial differences in the frequencies of D4DR exon III repeat polymorphism.
