A polymorphism within the serotonin transporter gene (SERTPR) has been repeatedly associated to mood disorders and response to SSRIs treatment. Recent evidence suggested that influence of genetic effect of SERTPR might be modulated by stress, particularly as regard the development of anxious-depressive symptoms. Nevertheless, there is no information about the role of stressors as potential modulator of SERTPR effects on depressive outcome during pharmacological treatment. In a sample of 159 mood disorder patients treated with fluvoxamine, we found stressors; preceding the onset of the illness significantly influencing the genetic effect exerted by SERTPR on response after 6 weeks of treatment. This preliminary finding supports the idea of complex interaction between biological and environmental factors underlying the efficacy of biological treatments, other than liability for mood disorders. Nevertheless, many limitations characterize the present investigation and well-funded studies on larger samples are required. (C) 2008 Elsevier B.V. and ECNP. All rights reserved.
