Study supports a causal role in narcolepsy for a common genetic variant
Results show a remarkable genetic association of almost 100 percentDARIEN, IL – A new study conducted across Europe found an extraordinary association between narcolepsy and a specific gene variant related to the immune system. The modified genome-wide association study involved 1,261 people with narcolepsy, representing nearly 90 percent of European patients suffering from narcolepsy with cataplexy who have complete diagnostic work-up and DNA available. They were matched with 1,422 controls. High-resolution genotyping identified genetic variants including those in the human leukocyte
