| Outline of Final Research Achievements |
Aggressive immunosuppressive therapy is often required for the treatment of rheumatoid arthritis, and methotrexate (MTX) is used as an anchor drug. Recently, MTX-associated lymphoproliferative disorder (MTX-LPD), which occurs during MTX administration, has attracted attention as a serious complication. In this study, we collected samples and performed a comprehensive genetic analysis with the aim of identifying genetic risk factors for MTX-LPD. Unfortunately, we were not able to identify significant genetic risk factors, but our findings are useful for future research.

| Academic Significance and Societal Importance of the Research Achievements |
関節リウマチの治療における第一選択薬であるメトトレキサート（MTX）の重篤な合併症の1つに、MTX関連リンパ増殖性疾患（MTX-LPD）があげられる。本研究ではMTX-LPDの遺伝的危険因子を同定することを目的に、試料収集、網羅的な遺伝子解析を行った。残念ながら検定力の不足により、有意な遺伝的危険因子の同定には至らなかったものの、今後も試料収集を続けることで将来的にはその同定の可能性が高いと考えられた。また多くの患者試料で得られた全ゲノム領域の遺伝子多型同定の結果は他の関節リウマチ関連遺伝子解析にも役立てることが可能である。
