Dopamine D2 receptor (DRD2) and dopamine D3 receptor (DRD3) genes could be candidates for personality-related genes considering their pharmacological profiles or structures. However, a limited number of studies have investigated the association between these genes and personality traits. In the present study, we investigated the DRD2, DRD3, and tyrosine hydroxylase (TH) genes in relation to personality traits in the Japanese population. Epistasis (gene-gene interaction) among the genes was extensively analyzed, in addition to the analysis based on each gene.
