on the association between the 5-HTTLPR polymorphism in the serotonin transporter gene and the personality trait neuroticism has been highly cited and was one of the first papers in personality genetics.
Other studies have associated neuroticism with genetic variations, e.g., with 5-HTTLPR — a polymorphism in the serotonin transporter gene.
5-HTTLPR |
Gene variants that have been investigated are, e.g., 5-HTTLPR in the serotonin transporter gene and gene variants in XBP1.
