New research links narcolepsy with cataplexy to a genetic variant

New research in Europe shows that almost 100% of study subjects who had a particular variation in the HLA-DQB1 gene had narcolepsy with cataplexy.  The findings are published in the January 2014 issue of the Journal Sleep.

“This almost 100 percent association with HLA is somehow unique to narcolepsy and suggests a causal implication,” lead author Mehdi Tafti, professor at the University of Lausanne in Switzerland.

The researchers suggest that in the future, DQB1 genotyping could become a way to diagnose narcolepsy with cataplexy.
