Figure 8B shows the correlation of selected allele-specific signals across the whole genome. For instance we find a strong allelic correlation between POL2RA and BCLAF1 binding, as well as negative correlation between H3K79me2 and H3K27me3, both at genes (below the diagonal, bottom left) and chromosomal segments (top right). Overall we find that positive allelic correlations among the 193 ENCODE assays are stronger and more frequent than negative correlations. This may be due to preferential capture of accessible alleles and/or the specific histone modification and TF, assays used in the project.
