Association between serotonin transporter genotype and extraversion.

Psychiatric genetics - 1 Dec 2007

Abstract excerpt

Despite the long-standing recognition that extraversion is partially heritable, few specific genes have been found to be associated significantly with this personality trait. The purpose of this study was to examine the association between a functional genetic polymorphism of the serotonin transporter promoter region (5-HTTLPR) and extraversion. Caucasian participants (N=183) were genotyped for the 5-HTTLPR;...
