HLA-DR2
Active
Description
HLA-DRB1*1501 and DRB1*1503, subtypes of DR2, are associated with narcolepsy. There is a strong association between HLA DR2/DQ1 and idiopathic narcolepsy in both the Japanese and Caucasian population. Studies between the Japanese and Caucasian population have shown 85 to 90% of individuals diagnosed with narcolepsy have DR2/DQ1. In Blacks, DR5 may be present instead of DR2, however, nearly all have DQ1. The absence of DQ1 in a patient with negative clinical findings is strong evidence against the diagnosis of narcolepsy.
