A significantly higher incidence of the KIR3DL2(+)/HLA-A3/11(-) genotype was found in the myeloid leukemia group compared to the healthy control group (AML vs. controls: 88.2% vs. 65.9%, p=0.047, CML vs. controls: 83.3% vs. 65.9%, p=0.047). This evidence concerns the gene KIR3DL2 and myeloid leukemia.
