Abstract

The tryptophan hydroxylase-2 gene (TPH2) codes for the enzyme of serotonin (5-HT) synthesis in the brain and variation of TPH2 has been implicated in disorders of emotion regulation. Here, we used functional magnetic resonance imaging (fMRI) to demonstrate that a potentially functional variant of TPH2 modulates amygdala responsiveness to emotional stimuli of both negative and positive valence.
