HLA-DQA~DQ heterodimer Antigens

Serologic combinations of HLA-DQA~HLA-DQ heterodimer Antigens

As of the 2026 Nomenclature Report, it is now possible to define a nomenclature for the paired combination of both subunits of HLA-DQ molecules. Antigens of DQA1 are listed as DQA, antigens of DQB1 are listed as DQ.

Below lists those proteins encoded in cis by common DQ haplotype blocks:

• DQA01~DQ6
• DQA02~DQ2
• DQA02~DQ9
• DQA03~DQ2
• DQA03~DQ4
• DQA03~DQ7
• DQA03~DQ8
• DQA03~DQ9
• DQA04~DQ4
• DQA04~DQ7
• DQA05~DQ2
• DQA05~DQ7
• DQA05~DQ9
• DQA06~DQ7
