Outline of Research at the Start

ヒトゲノムに存在する構造多型の25%はこれまで"ジャンク"だと考えられてきた転移因子の挿入多型である。本研究では独自に開発した解析手法を用い、日本人を含む1万人規模のヒトゲノムから転移因子の挿入多型を探索する。次に、これらの多型を用い遺伝統計解析を行う。具体的には、ゲノムワイド関連解析(GWAS)やeQTL解析を行い、転移因子多型と疾患や遺伝子発現との関連を明らかとする。いくつかの転移因子多型に関しては実際に転移因子が疾患の原因となるかを細胞生物学実験により検証する。本研究はこれまで着目されてこなかった転移因子多型に遺伝統計手法を適用し、遺伝性疾患の病因を理解する上で重要な知見を得る。

Outline of Final Research Achievements

This research has made three achievements. 1) Development and open-source release of MEGAnE, a software that can precisely detect and genotype mobile element variations (MEVs). 2) GWAS of MEVs in Biobank Japan. We performed MEV GWAS and found one MEV in NEDD4 gene is one genetic cause of keloid, a skin disease. We reported this result in Nature Genetics (applicaint is the first and co-corresponding author). 3) Publishment of a review paper. I summarized statistical genetics of MEVs and published a review paper in Human Genome Variation (applicaint is the first and corresponding author).

Academic Significance and Societal Importance of the Research Achievements

疾患の遺伝要因の特定は、精密医療の実現の鍵となる。ゲノムワイド関連解析(GWAS)は疾患の遺伝要因を網羅的に調べる手法だが、大半のGWASは一塩基多型のみを使用しており、疾患の原因となる構造多型を見つけることができない。本研究により、ヒトの構造多型の25%を占める転移因子多型を遺伝統計解析することが可能となった。つまり、これまで見過ごされてきた疾患の遺伝要因の特定が可能となり、疾患の予防法開発と治療法開発、精密医療の推進に貢献することが期待される。実際に本研究では皮膚病変の原因変異を特定した。本結果は今後、皮膚病変リスクのより良い評価手法の開発や皮膚病変の治療開発に役立つ。
