Abstract:
The genetic variant rs16754 of Wilms tumor gene 1 (WT1) has recently been described as an independent prognostic factor in AML patients. It is of great interest to test whether WT1 single nucleotide polymorphism can be used as a molecular marker in other types of cancer, to improve risk and treatment stratification. We performed sequencing analysis of exons 7 and 9 of WT1, which are known mutational hotspots, in a total of 73 patients with BCR-ABL1-negative myeloproliferative neoplasm (MPN) and 93 healthy controls. No previously reported WT1 mutations were identified in the present study. In Korean patients with BCR-ABL1-negative MPN, WT1 genetic variant rs16754 had no significant impact on clinical outcomes. We observed a significant difference in the allelic frequencies of WT1 rs16754 in Koreans between BCR-ABL1-negative MPN cases and healthy controls. Individuals carrying variant G alleles of WT1 rs16754 showed a relatively low prevalence of BCR-ABL1-negative MPN, compared with those carrying wild A alleles of WT1 rs16754 (Hazard ratio 0.10-0.65, P<0.05). Therefore, possession of the variant G allele of WT1 rs16754 may reduce the risk of developing BCR-ABL1-negative MPN.
