Outline of Final Research Achievements

Top genes that cause gene mutations at a frequency of 10% or more (VHL; 71.40%, PBRM1; 57.10%, SETD2; 42.90%, KDM5C; 20.00%, TTN; 17.10%, CACNA1I; 17.10%, BAP1; 14.30%, We comprehensively analyzed the ccRCC database of 1744 people (1813 samples) regarding DYNC1I1; 11.40%, MTOR; 11.40%) to assess the impact of genetic variants on the survival of ccRCC patients. SETD2 had the highest impact on patient survival among somatic mutations in renal cancer.

Academic Significance and Societal Importance of the Research Achievements

いずれの腎癌免疫療法も効果が限定的である理由と解決のヒントは不明である。有力な原因遺伝子を同定し、将来、治療感受性を向上できるのであろうか。腎癌の分子病態の全容解析からすでに重要性が判明しているSETD2の免疫療法における役割の解析は直ちに取り組まないといけないもので、その結果は社会に還元できるものと考える。
