Outline of Final Research Achievements |
The purpose of this project is to investigate underlying mechanism of clinical "outlier" among pediatric leukemia, using detailed genomic analysis. As major findings of this project, we identified a novel fusion of RARB in acute promyelocytic leukemia which lacked typical translocation, and confirmed the pathogenic role for leukemogenesis. We also established a precise genotyping method of NUDT15 variants conferring sensitivity to mercaptopurine, a one of the key drugs for acute lymphoblastic leukemia. Through these findings, we confirmed an importance of genomic analysis to understand clinical outlier.

Academic Significance and Societal Importance of the Research Achievements |
非典型的な経過を取る小児白血病の病態には、それぞれ特有のゲノム異常が強くかかわっていることが確認された。ゲノム解析は標準的な検査では病態が把握できない、もしくは通常の臨床経過と異なる非典型例の病態を理解することにつながり、白血病の診療にあたってゲノム診断を実施することの重要性を検証する結果が得られた。
