Outline of Annual Research Achievements |
BAF複合体の構成サブユニットをコードする遺伝子群に異常を認めないコフィン-サイリス症候群症例とその両親のゲノムDNAを用いて、次世代シークエンサーによる全エクソーム解析を行った。その結果、2例においてSOX11にde novo変異を見出した。転写因子であるSOX11はBAF複合体ネットワークの下流で、神経細胞の分化制御などに重要な役割を果たしていることが報告されている。本遺伝子がヒトの脳組織で発現していること定量PCR法により確認し、モデル実験動物のゼブラフィッシュにおいて、モルフォリノアンチセンスオリゴにより相同遺伝子の機能を阻害すると、頭部の縮小、中枢神経の細胞死などの異常が認められ、CSSの症状を模倣していた。これまでにCSS症例では、BAF複合体の構成サブユニットをコードする5つの遺伝子の変異が報告されていたが、新たにSOX11が同定されたことにより、本疾患の遺伝子診断の正確性が向上した。また、新たな責任遺伝子が解明されたことで、さらにCSSの病態解明と治療・予防法の開発に進展することが期待される。
