Outline of Annual Research Achievements |
次世代シーケンサー(NGS)を用いて、全ゲノムシーケンス(WGS)を行い、染色体構造異常を明らかにすることを目的として研究を進めた。WGSは1サンプルあたりの解析コストを抑えるため通常のスタンダードな30xカバレージではなく読み取り深度を5x~20x程度として解析を進めた。解析には、複数のソフトウェアをトライしBreakDancerを選択して解析を進めた。個々のNGSのリードの詳細な解析にはIntegrated Genome Viewer (IGV)を利用した。解析には、あらかじめ通常の染色体検査で構造異常が明らかでその一部ですでに構造異常切断点の解析が進められた10症例を選択した。均衡型転座を有する8例(うち1例では2種類の転座を有する)と、逆位を有する2例を用いた。この結果、転座については、18転座切断点のうち15を(83%)、4逆位切断点では全てを(100%)塩基レベルで決定することが示された。これらのデータはNGSによる読み取り深度の浅い全ゲノム解析で比較的容易に構造異常解析が可能でありことが示された。本解析は、あらかじめ染色体構造異常が明らかな症例のみを用いており、染色体構造異常が不明な状況下でblindで効率よく染色体構造異常が同定できるのかは今後の課題である。
