A recent study from Germany showed that WT1 single nucleotide polymorphism (SNP) rs16754 was an independent prognostic factor in cytogenetically normal acute myeloid leukemia (CN-AML). We analyzed clinical impact of the WT1 rs16754 genotype on disease characteristics and outcomes in Korean patients with CN-AML. A total of 73 patients with CN-AML were included in the study. All patients received standard induction chemotherapy and their bone marrow or peripheral blood samples were cryopreserved at the time of diagnosis. WT1 exons 7 and 9 were amplified using polymerase chain reaction and directly sequenced. The genotype frequency for WT1 rs16754 was 6.8% for AA, 39.7% for GA, and 53.4% for GG. G was a minor allele in German population, whereas it was a major allele in Korean (13.7% vs. 73.3%, P < 0.001). Complete remission was induced in 85.3% of patients with GA/AA and 84.6% of those with GG (P = 0.936). Survival rates were also similar between patients with GG and those with GA/AA. Asian and Western populations exhibited significant differences in allele and genotype frequencies of WT1 rs16754. In Korean patients with CN-AML, WT1 SNP rs16754 had no significant impact on clinical outcomes and further investigations are needed to define prognostic implication of WT1 SNP rs16754 in CN-AML.
