What genes or chromosomes are affected by narcolepsy?
A variation of the HLA-DQB1 gene called HLA-DQB1*06:02 has been strongly associated with narcolepsy, particularly in people who also have cataplexy and a loss of hypocretins. Most people with narcolepsy have the HLA-DQB1*06:02 variation, and many also have specific versions of other, closely related HLA genes.
