Neuroticism, a fundamental personality trait characterized by anxiety, moodiness, worry, envy and jealousy
Other studies have associated neuroticism with genetic variations, e.g., with 5-HTTLPR — a polymorphism in the serotonin transporter gene.

Another study has found that healthy subjects with a high neuroticism score tend to have higher DASB binding in the thalamus; DASB is a ligand that binds to the serotonin transporter protein.
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.
