Subtle changes in chromatin loop contact propensity are associated with differential gene regulation and expression.

Across cell types and haplotypes, we found a positive and highly significant correlation (Pearson correlation; cell type: p = 2.36 × 10 −30 , haplotype p = 6.76 × 10 −4 , Fig. 7d ) between gene expression fold change and chromatin loop fold change, and between H3K27ac fold change and loop fold change (Pearson correlation; cell type: p = 6.6 × 10 −211 ; haplotype: p = 4.63 × 10 −5 , Fig. 7e ).
