We also identified genes with a broad H3K4me3 domain in a specific colorectal cancer cell line but not in normal cells, which could be attributed to intertumoral heterogeneity or a cluster of genes on chromosome X in HCT 116 cells, e.g., MAGE Family Member A2 (MAGEA2) (Figure 9B). Here, MAGEA2 is linked to colorectal cancer.
