Research Abstract

1 てんかんの責任遺伝子同定
JMEを含む特発性全般てんかん患者123例と360例の健常対象でCACN1Gを解析し、5種類のアミノ酸置換を伴う13バリアントを見いだし、その中には対照群では存在しない変異が含まれていた。また、AP3M2がてんかんの感受性遺伝子たり得るか否か検討する目的で6種類のてんかん類型を含む190人の患者でスクリーニングし、21種類のバリエーションを見いだし、内、16種類は新規のバリエーションであった。Direct sequencingで変異の認められなかったSMEI30症例をsemi-quantitative PCR法(multiplex ligation-dependent probe amplification : MLPA)を用いて解析したところ、6症例で複数のエクソンの欠失やSCN1A遺伝子の1コピー全体の欠損などを認めた。
2 新たな遺伝子解析の手段としてGene Chip Mapping Arrayを用いたゲノム切断点の解析が有力であることを証明し、現在、この方法とMLPAで新たな熱性けいれん及びてんかんの責任遺伝子を探索中である。
3 てんかんの分子病態の解析
これまでに研究グループで見いだした遺伝子変異の機能解析を進めている。これまでに作出した遺伝子改変動物でepileptogenesisとictogenesisを脳発達の観点から解析中である。またこれらのモデル動物で遺伝子変異の種類とAEDに対する反応性を発射頻度、発作頻度を指標として直接的に解析している。
4 臨床的には部分発作に対するtopiramate、levetiracetamの効果を公表した。500例以上の健常対照群でCYP、transporterのすべての既知の多型頻度解析を行い、加えてAED単剤で治療中のてんかん患者の例数を積み重ねている。
5 新たに同定した遺伝子変異を利用したてんかん診断方法に関する特許を公開した(SMEIに関連するKCNJ10と14,GES+に関連するKCNJ13,BFNC12に関連するKCNJ13,及びADNFLEに関連するKCNJ16変異)。
