Pain-related comorbidity in depression: the association with 5-HTTLPR and STin2.

A conference paper on the relationship between the presence of comorbidity, with or without pain, and serotonin transporter genotype in major depressive disorder is presented. One hundred sixty-four patients meeting the DSM-IV criteria for major depressive disorder were included in the analyses. Findings underscore a slightly increased risk of developing comorbidity with the serotonin transporter genes 5-HTTLPR and STin2.
