The serological reaction of DR9 is relatively good. The serology of DRB1*0902 to *0906 serotypes is unknown.
Disease associations
DRB1*0901: Early childhood myasthenia gravis[2]
Extended linkage
DRB1*0901:DQA1*0301:DQB1*0303 haplotype: Early childhood myastenia gravis[2]
Genetic linkage
HLA-DR9 is genetically linked to HLA-DR53, and HLA-DQ3 and DQ9 serotypes.
