The serotonin transporter gene (SLC6A4; 5-HTT; SERT) is considered a prime candidate in pharmacogenetic research major depressive disorder (MDD). Besides genetic variation, recent advances have spotlighted the involvement of epigenetic mechanisms such as DNA methylation predicting antidepressant treatment response "pharmaco-epigenetic" approaches. In MDD, lower SLC6A4 promoter has been suggested to predict impaired serotonergic antidepressants. present study sought replicate and extend this finding large, independent sample MDD patients.The comprised n = 236 Caucasian patients with receiving medication naturalistic setting.
