Gene Variations In Diverse Patient Populations Determine Who Responds Best To An Antidepressant

A new Mayo Clinic study shows that variations in the serotonin transporter gene could explain why some people with depression respond better than others to treatment with citalopram (Celexa), an antidepressant medication. The study, in the current issue of the American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, examined the serotonin transporter gene, or SLC6A4, in 1,914 study participants.
