From: A genetic association study of DNA methylation levels in the DRD4 gene region finds associations with nearby SNPs

Figure 4

Average percentage DNA methylation across CpG sites in the DRD4 region by genotype groups at 4 associated SNPs. Error bars denote standard deviation. * = significant associations at the p < 0.05 level. Though association analyses were conducted on arcsine transformed data, the true proportion of methylation observed is plotted here. The one homozygous TT subject at rs752306 within our sample was collapsed with the heterozygote group in association analyses.
