Narcolepsy is a multigenic environmentally influenced neurologic sleep disorder affecting 0.01 to 0.15% of the population. Among other genetic regions, it is associated with the HLA class LI region of the HLA complex. HLA-DQ6 and/or HLA-DR15 confer susceptibility to narcolepsy, with variable relative risk according to ethnicity.
