The DR15-DQ6 haplotype may afford some greater protection against the progression of HIV.
HLA | HLA-C | HLA-DQ1 | HLA-DQ5 | HLA-DRB1 | HLA-DR16 | HLA-DR15 | HLA-DQ8 | HLA-DQ7 | HLA-DQ2 | HLA-G | HLA-E | HLA-DR14 | HLA-DR13 | HLA-DR12 | HLA-DR11 | HLA-DQ9 | Hla Myint | HLA-DRB5 | HLA-DRA | HLA-DR7 | HLA-DR52 | HLA-DR4 | HLA-DQ4 | HLA-DQ3 | HLA-DPB1 |
For DQ6, however, cis-isoform pairing only occurs with DQ1 α-chains.
HLA-DR2 (DR2) of the HLA-DR serotype system, is a broad antigen serotype that is now preferentially covered by HLA-DR15 and HLA-DR16 serotype group.
