Shown are the levels of statistical significance (P values) of associations with CpG islands, CAGE tag shape classes, promoter expression, and imprinting candidates, where the Fisher's exact test is used for the null hypothesis that the two examined sets do not have any positive associations. *Statistically significant findings. CAGE, cap analysis of gene expression.
