DQB1*0602 is a better genetic marker than DR2 for narcolepsy susceptibility across all ethnic groups; for instance, only 75% of African American narcoleptics are DR2+ compared with 96% DQB1*0602+. We studied DRB1 genes of DR2- but DQB1*0602+ African American patients with cataplexy and observed two with an unusual DR12, DQA1*0102, DQB1*0602 haplotype; a new allelic variant of DRB1*1202 has been designated DRB*12022. 8 refs.
