Figure 6

DRD4 percentage DNA methylation levels in CEPH transformed lymphoblastoid cell lines and post-mortem Singular Frontal Gyrus tissue (SFG). a) Average DRD4 DNA methylation levels plotted by rs3802971 genotype b) DNA methylation levels across individual DRD4 CpG sites plotted by rs3802971 genotype group. * = significant associations at the p < 0.05 level. Though arcsine transformed data were used in analyses, the true proportion of DNA methylation observed is plotted here. The one heterozygous subject in the post-mortem brain tissue sample was combined with the TT homozygotes for analyses.
