Narcolepsy-Associated Antigen, HLA-DQB1 Typing, Blood
Clinical Information: Narcolepsy is a neurological condition affecting about 0.02% to 0.16% of
African American, Caucasian, and Japanese individuals. It can be quite disabling because it is
characterized by abnormal rapid eye movement (REM) sleep, cataplexy, hypnagogic hallucinations, and
sleep paralysis. Studies have identified DQB1*06:02 as a useful marker of narcolepsy. While
DQB1*06:02 is found in virtually all African American, Caucasian, and Japanese narcoleptics, it must be
clearly understood that some patients do not have this allele and, more importantly, about 25% of normal
people have this gene. Because DQB1*06:02 is present in the normal population, no test for an HLA gene
constitutes a test for narcolepsy. A more reliable approach would be to consider that, in an appropriate
patient, the absence of the strongly associated DQB1*06:02, provides good evidence that the patient does
not have narcolepsy.
Useful For: Ruling out a diagnosis of narcolepsy
Interpretation: If DQB1*06:02 is not detected, the narcolepsy-associated antigen test result will be
reported as negative for DQB1*06:02. If the allele is detected, the result will be reported as positive for
DQB1*06:02.
