Research Abstract

性分化異常を伴うX連鎖性・サラセミア精神遅滞(ATR-X)症候群はクロマチン調節関連蛋白をコードするATRX遺伝子の異常が原因である。性分化異常は多様で,症例の約80%に観察されるが,その発症機序は全く不明である。一方,ATR-X症候群患者細胞ではリボゾーマルDNA(rDNA)等のDNAメチル化異常が存在し,ATR-Xにおける性分化異常の発症にゲノムDNAメチル化を含むエピゲノム異常が関与する可能性が極めて高い。本研究ではATR-X特異的なDNAメチル化異常を同定しその領域に存在する遺伝子群を明らかにする目的でゲノムワイドなDNAメチル化異常探索を行っている。種々の検討の結果,本研究に最適なプラットフォームをAgilent社のCpGアレーと決定し,メチル化シトシン抗体を用いたChIP on chip法と,メチル化感受性制限酵素を用いたプローブ調整法の2つの異なる手法でATR-X患者細胞特異的なメチル化異常部位を多数同定した。現在,個々の症例におけるメチル化の検討を行っており候補遺伝子探索を続けている。また新規のATR-X症例のATRX変異解析も平行して行い新規症例の集積の努力を行っている。
