Takayasu arteritis (TA) is a chronic large-vessel vasculitis of unknown etiology. Human leukocyte antigen (HLA) alleles play an important role in the development of TA. Sequence specific primer-polymerase chain reaction was used to detect 10 alleles of the HLA-DQA1 gene and 13 alleles of the HLA-DQB1, -DRB1 gene. A significant increase in the frequencies of DRB1(∗)07 (Pc<0.01, OR=3.44, CI: 2.15-5.52) was observed among TA patients compared with the control group. The significantly increased frequencies of the haplotype DQA1(∗)03:01-DQB1(∗)03:01-DRB1(∗)07 (Corrected P-values<0.01) were observed in TA patients. But in the analysis of clinical manifestations, there are no significant associations with the HLA-DRB1(∗)07 allele.
