| Outline of Final Research Achievements |
Because genetic factors may contribute partly to the etiologies of inner
ear diseases, we investigated the association between genetic polymorphisms located in genes related to the inflammatory pathway and susceptibility to Meniere disease and tinnitus. We found that uncoupling protein 1, 2 polymorphisms were significantly associated with the risk of tinnitus and platelet glycoprotein Ia polymorphism was associated with the risk of Meniere disease.

| Academic Significance and Societal Importance of the Research Achievements |
内耳性難聴や耳鳴は、病態は不明の点が多いが、環境要因や遺伝要因含めた多因子によるものと考えられる。本研究の成果により耳鳴やメニエール病で遺伝要因の関与が考えられた。内耳MRI画像の進歩により内耳血管透過性亢進や内リンパ水腫の評価が可能となった。画像所見も含めて病態を分類し、内耳性難聴や耳鳴の個別化医療に向けての基礎的なデータになることが考えられる。
