Positive pairwise associations were also found in TET2 and POTEG, GATA2 and AHNAK, and CSF3R and ASXL2. Only GATA2 showed significant mutual exclusivity with KMT2A. KEGG pathway enrichment analysis revealed that the mutated genes, including CEBPA, were mainly involved in cancer (Figure 3B). The gene discussed is GATA2; the disease is cancer.
