A polymorphism in the regulatory region of the serotonin transporter gene (5-HTTLPR) was found to be associated both with the personality trait of neuroticism and with seasonal changes in mood and behavior, or seasonality. 5-HTTLPR is a variation in the promoter region of the serotonin transporter gene (SLC6A4).<\/p>\n<p>We measured 5-HTTLPR genotypes and both psychological traits in 236 healthy volunteers. The 5-HTTLPR was significantly associated with both neuroticism and seasonality. The results indicated that the 5-HTTLPR contributions to variation in the two traits are largely independent. Approximately three-quarters of the effect of the gene on seasonality are not related to its effects on neuroticism. The gene has a larger effect on the covariation between neuroticism and seasonality than it does on either trait alone. Sibling-pair analysis confirmed that the effects of the serotonin transporter gene are due to genetic pleiotropy rather than population stratification.<\/p>\n<p>Reference<\/p>\n<p>1.
