| Abstract: | Objective The purpose of this study was to examine the association of interleukin-1 receptor-associated kinase (IRAK1) polymorphisms (rs3027898, rs1059702) with systemic lupus erythematosus (SLE) in a Chinese Han population. Methods A total of 667 SLE patients and 667 healthy controls were collected in this study. The genotyping of polymorphisms (rs3027898, rs1059702) was determined by TaqMan allele discrimination assay on the 7300 real-time polymerase chain reaction system. The statistical analysis was conducted by chi square test or Fisher’s exact test. Results The frequency of C allele for rs3027898 in patients was significantly higher than in controls (C versus A: OR = 1.438, 95 % CI = 1.180–1.753, p < 0.001), and a similar association was shown in rs1059702 (A versus G: OR = 1.383, 95 % CI = 1.143–1.674, p = 0.001). Interestingly, the C allele of rs3027898 was associated with a decreased risk for patients with oral ulcers. However, no significant difference was detected in IRAK1 rs1059702 polymorphism and the clinical manifestations. Conclusions Our data demonstrate that the polymorphisms rs3027898 and rs1059702 of IRAK1 gene are associated with SLE in the Chinese Han population. |
