HLA-DR6 (DR6) is a broad-antigen serotype that is further split into HLA-DR13 and HLA-DR14 antigen serotypes.

DR6 serological reactivity is relatively poor compared to other serological tests for DR antigens. Compare to DQ2 or DR7.

Disease associations

edit

DR13 and DR14 share a common association to myasthenia gravis.[6]

Allele groups

edit

HLA-DRB1*13 and HLA-DRB1*14 encode serotypes of DR6.
