Abstract
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.
