過眠症(ナルコレプシー)に関連した遺伝子を発見!

2008年9月29日付けのYOL(Yomiuri On Line)によると、東京大の徳永勝士教授(人類遺伝学)らのグループが、「過眠症(ナルコレプシー)」に関連した新たな遺伝子を発見したそうです。過眠症とは、「昼間なのに突然激しい眠気を感じて眠ったり、突然全身が脱力したりする病気」なのですが、この発見によって、近い将来、過眠症の原因が明らかになって、治療法が開発されると良いですね。同グループの論文は、29日に「科学誌ネイチャー・ジェネティクス(電子版)」に掲載されます。

According to today’s YOL(Yomiuri On Line), a research group led by Professor TOKUNAGA, Katsushi at the Univeristy of Tokyo has discovered a new gene linked to the onset of narcolepsy. Typcial syndrome of narcolepsy includes ‘suddenly feeling excessive sleepiness during the day time and fall asleep immediately’ or ‘a sudden loss of muscle tone (known as ‘cataplexy’). Through this discovery, it is hoped that the cause of narcolepsy becomes clear and a new treatment of the disease will be developled in the near future. The article is going to be published on the electronic version of  a US Science journal of ‘Nature Genetics’ on 29 September.
