Outline of Research at the Start

RNF213 p.R4810K多型は、本邦を含む東アジア人で一般人口の2~3%にみられる。この多型を保有する脳梗塞やもやもや病(RNF213 脳血管症)ではてんかん発症率が13~30%と高値を示し、血管系の異常だけではなく、新たなてんかん発生機序も想定される。本研究では大規模ゲノムレジストリのSNPアレイ解析結果RNF213 多型保有者のてんかん発症機序を明らかにし、脳卒中後てんかん発症を予測するためのpolygenic risk scoreを開発する。

Outline of Annual Research Achievements

国立循環器病研究センターゲノムレジストリを利用してデータ整備と解析を進めた。さらに、Newcastle大学(英国)、University College London(英国)、University Hospital Zurich(スイス連邦)と連携し、脳卒中後てんかんに関する国際共同コホート研究の体制を構築した。
脳卒中後てんかんのnarrative reviewを投稿し、Neurology誌に採択された。
また、脳卒中後てんかんにおいて、発作急性期脳波上のlateralized periodic discharges (LPDs)、特に速波が重畳したもの(LPDs+F)の存在が、その後の経過における機能予後悪化に関連していることを明らかにし、Epilepsia誌にて採択された。また、脳卒中後てんかんにおける発作後過灌流の促進因子と抑制因子を明らかにし、第35回国際てんかん会議(International Epilepsy Congress)で報告した。

Current Status of Research Progress
Current Status of Research Progress

2: Research has progressed on the whole more than it was originally planned.

Reason

ゲノムレジストリデータの整備と解析を進めた。また、国際共同研究体制を構築しデータ共有の準備を進めた。さらに、脳卒中後てんかんに関してレビューを含めて幾つかの論文報告を行った。

Strategy for Future Research Activity

ゲノムレジストリを用いて、遺伝情報と画像情報を統合した解析を行い、RNF213 p.R4810K多型と脳卒中後てんかんとの関連を明らかにし、脳卒中後てんかんの予測モデルを構築する予定である。さらに、海外のコホートを用いた外部検証を予定している。
