Outline of Research at the Start

小児ALL発症の遺伝的背景の全貌はまだ十分に解明されていない。これまで小児ALL患者582例のゲノムワイド関連解析から幾つかの疾患感受性ローカスを同定し、またB細胞分化にかかわる転写因子に注目し、レアバリアントを同定した。さらに、乳児ALL52例から、新規疾患感受性遺伝子候補を同定した。本研究では、これらの同定された候補遺伝子の機能解析やゲノム疫学解析により小児ALL発症にかかわる新規疾患感受性遺伝子を同定し、小児ALL発症に関する遺伝的背景の実態を明らかにする。

Outline of Final Research Achievements

To explore the genetic background of childhood acute lymphocytic leukemia (ALL), we analyzed genes involved in B-cell differentiation and identified 6 PAX5 and 8 TCF3 rare variants.
One patient with a variant of PAX5 was common variable immunodeficiency. Knock-in mice with this variant showed abnormal B cell differentiation and susceptibility to leukemogenesis.TCF3 variants retained normal transcriptional function. Therefore, in collaboration with a U.S. group, we analyzed 4,405 ALL samples and identified 106 variants, 8 of which were nonsense mutations.
We identified the PAX5 rare variant in familial cases of ALL. We identified additional 2 families and their clinical features, immune abnormalities, and genetics were characterized.

Academic Significance and Societal Importance of the Research Achievements

小児急性リンパ性白血病(ALL)の遺伝的な背景を明らかにすることにより、小児ALLの発症に関わる病態解明につながることが予測される。今回の研究により小児ALLの一部はB細胞分化にかかわる転写因子の異常を背景としていることが明らかになり、将来的にはこういった分子を標的とした治療法開発につなげていく必要があると考える。また小児ALLの一部が遺伝的な背景のもとに発症しているということは遺伝カウンセリングの適切な介入が必要なことを意味し、将来的な患者ケアに役立つ情報となると考える。
