Scientists in Japan have identified a genetic mutation linked to narcolepsy, a disease that can cause someone to doze off in
mid-sentence or behind the wheel of a car, a study reports.
Genetic variant common in Koreans
The statistical link was strongest among Japanese, but remained
significant among Europeans and persons of African descent as well.
The study also showed that the suspect genetic variant - known as
rs57770917 - is common among Koreans.
