Description:
Narcolepsy is a chronic, debilitating sleep disorder. One of the most important associated genetic factors is the HLA-DQB1*06:02 allele on the DRB1*15:01-DQA1*01:02-DQB1*06:02 haplotype. Between 85 and 95% of narcolepsy patients with cataplexy carry this haplotype. Persons homozygous for HLA-DQB1*06:02 carry a greater risk than heterozygous persons. The detection of HLA-DQB1*06:02 typing is useful as an aid to diagnosis in patients with cataplexy.
