Japanese scientists identify the gene causing sleep during the day
Scientists in Japan to identify different gene may be linked to the situation of twilight sleep (shift in times of the day sleeping), a condition characterized by extensive sleep during the day and the lack of clarity of vision and muscle weakness.
This situation is occurring in one out of every two thousand five hundred people in the United States and Europe, but more frequently at least four times between Japanese.
The researchers analyzed a set of genetic factors or the DNA of the 222 wounded Japanese situation twilight sleep, and 389 others are suffering from this situation.
The researchers said in a report published in the journal "Nature Jinteks" He appeared a different gene significantly affected by repeating cataplexy.
The Professor of the Department of Katsuchi Tokonaja "human gene" in the University of Tokyo in a telephone interview that "45% of those who suffer from the twilight sleep with this altered gene, compared with 30% among those who do not suffer from this situation."
He added that the identification of this gene could pave the different ways to experts to search for a cure.
It is called methylation of this gene (CP my T-1) and (CH KP), both of the apparent connection to this imbalance, and control gene (CP my T-1) in the enzyme regulates sleep, while the gene (CH KP) linked Sleep cycle and vigilance.
Scientists took a further step in examining the different between this gene Korea 424, and 785 people come to Europe, and 184 American of African descent.
A repetition of this gene significantly between Koreans living cataplexy, but these were not relevant and clear between the Europeans and Americans of African descent.
Tokonaja said, "We have no idea why the emergence of this gene altered such repetition of the large Japanese and Koreans living cataplexy, it may be a natural selection or by accident.
