title: The serotonin transporter promoter polymorphism and suicide.
abstract: Serotonergic dysfunction has been implicated in mood disorders and in the pathophysiology of suicidality. A functional polymorphism (a 44-base pair insertion (L)/deletion (S)) in the promoter of the gene encoding the serotonin transporter (5-HTTLPR), associated with mood disorders, has been inconsistently associated with suicidality. To add to this debate, we designed a case-control study involving 62 suicide victims and 72 controls matched for age, gender and ethnicity. All subjects underwent forensic investigation. No association could be detected between the 5-HTTLPR polymorphism and suicide. This result is consistent with the proposal that different genes are involved in hopelessness and suicidal behavior or in depressive illness.
