Dopamine beta-hydroxylase gene modulates individuals' empathic ability

Abstract

Dopamine beta-hydroxylase (DBH), an enzyme that converts dopamine to norepinephrine, has broad influences on social functions. In this study, we examined to what extent two polymorphisms (-1021C/T and a 19 bp insertion/deletion) in DBH gene modulate individuals' empathic perception and response, which were measured, respectively, by reading the mind in the eyes test and the empathic concern subscale of interpersonal reactivity index. Results showed that polymorphism at -1021C/T, but not the 19 bp insertion/deletion, accounts for 2.3% variance of empathic perception and 1.4% variance of empathic response. Individuals with the CC genotype, which is associated with higher DBH activity, manifested greater empathic ability than those with CT/TT genotypes. These findings demonstrate the importance of DBH -1021C/T as a genetic basis of empathy and in predicting individual differences in social and affective processing.

Keywords: DBH; dopamine beta-hydroxylase; empathy; polymorphism; −1021C/T.
