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 (
