文献購入ページに移動アルコールの吸収と代謝,アルコール代謝酵素遺伝子多型との関連,アルコール代謝酵素遺伝子多型とアルコール依存症との相関,遺伝子多型によって異なるアルコール依存症の臨床像といった点について紹介した.アルコール代謝には主にアルコール脱水素酵素(ADH1B),アルデヒド脱水素酵素(ALDH2)が関与するが,そのいずれにも遺伝子多型が存在する.非活性型ALDH2,代謝速度の速いADH1Bはいずれもアルコール依存症発症に予防的に働くことが知られているが,依存症の発症は遺伝因子だけで規定されるものではなく環境因子や精神科合併症などの様々な要因が関与する複雑なものであることについて説明した.
