Polymorphisms in IRF5 and TYK2 Genes Are Associated with Rheumatoid Arthritis in a Chinese Han Population.


ABSTRACT: BACKGROUND The IRF5 and TYK2 gene polymorphisms are associated with autoimmune diseases. However, the relationship between the IRF5 and TYK2 gene polymorphisms and RA risk in the Chinese Han population was inconsistent. MATERIAL AND METHODS A total of 578 RA patients (case group) and 578 healthy controls (control group) were assessed in a case-control study. Genotyping of IRF5 (Exon 6 insertion/deletion (in/de), rs2004640, rs2070197, rs10954213) and TYK2 (rs280500, rs280519, rs280521, rs8108236, rs12720253) was performed by direct sequencing method. Data analysis was performed by SHEsis. RESULTS The rs2004640T allele (P=0.0003) and the dominant (P=0.001) and recessive (P=0.01) models of rs2004640 were associated with RA risk after stringent Bonferroni correction (0.05/4). The IRF5 exon 6 (in), rs2070197 and rs10954213 were not associated with RA (P>0.05). Two haplotypes of IRF5 (DTAT and DTGG) were associated with RA susceptibility (P<0.05). In addition, the frequencies of TYK2 rs280500A, rs280521A, and rs8108236A were significantly higher in the RA group compared with the control group (P<0.05). TYK2 rs280500, rs280521, and rs8108236 were associated with RA susceptibility in the dominant model, but the same was not observed for rs280519 and rs12720253 (P<0.05). Furthermore, 3 risk haplotypes (AAAGT, AGGAT, and GAAAT) and a protective haplotype (GAGGT) of TYK2 gene were associated with RA susceptibility (P<0.05). CONCLUSIONS Our results suggest that IRF5 rs2004640, TYK2 rs280500, rs280521, rs8108236, and haplotypes IRF5 (DTAT and DTGG) and TYK2 (AAAGT, AGGAT, GAAAT, and GAGGT) are susceptible factors for RA in a Chinese Han population.
