Schematic overview and sequence of
promoter associated CpG island region. The positions refer to GeneBank accession number NG_011747.2. The numbers 1 to 4 refer to locations of the CpG sites assayed in the present study. CpG site 2 corresponds to CpG site cg22584138. (5-HTTLPR = SLC6A4-linked polymorphic region, S shore = South shore of CpG island, CpG island = cytosin-phosphate-guanine island, N shore = North shore of CpG island).
