  • CuratedUniProtKB
DQ2 (heterodimer of DQA1*05:01/DQB1*02:01) is associated with more than 90% of celiac disease patients. A minority displays DQ8 (heterodimer of DQA1*03/DQB1*03:02).  
  • CuratedUniProtKB
DQ0602 (heterodimer of DQA1*01:02/DQB1*06:02) confers dominant protection against type 1 diabetes (T1D) and strong susceptibility to narcolepsy. DQB1*06:02 has been found to be present in most of the narcolepsy patients. As well 98% of the patients with an HCRT deficiency are positive for DQB1*06:02.
