Abstract

The monoamine oxidase A (MAO-A) gene has been suggested to be involved in the pathogenesis as well as the pharmacological treatment of major depressive disorder. In the present analysis, for the first time a pharmacoepigenetic approach was applied investigating the influence of DNA methylation patterns in the MAO-A regulatory and exon1/intron1 region on antidepressant treatment response. 94 patients of Caucasian descent with major depressive disorder (f = 61; DSM-IV) were analyzed for DNA methylation status at 43 MAO-A CpG sites via direct sequencing of sodium bisulfite treated DNA extracted from blood cells. Patients were also genotyped for the functional MAO-A VNTR. Clinical response to an..
