IL4I1, KMO, and HADH demonstrated positive correlations with most checkpoints (PDCD1LG2, CD200R1, CD86, TNFSF15), whereas ACAT2 and ECHS1 exhibited inverse correlations, indicating differential roles of these genes in modulating the AML immune microenvironment (Figure 7C). The gene discussed is PDCD1LG2; the disease is acute myeloid leukemia.
