Functional polymorphism (5-HTTLPR) in the serotonin transporter gene is associated with subjective well-being: evidence from a US nationally representative sample

Variation in the promotor region of the serotonin transporter gene (5-HTTLPR) is a promising candidate for better understanding individual heterogeneity in subjective well-being or happiness, as measured by life satisfaction. This functional polymorphism has previously been associated with mental health and selective processing of positive and negative… (More)
