Abstract:
OBJECTIVETo investigate the association of 1858C/T polymorphism of protein tyrosine phosphatase nonreceptor type 22 (PTPN22) and rheumatoid arthritis (RA) susceptibility.
METHODSCMB, wanfang (Chinese) and PubMed databases were searched to get the studies on the association between 1858C/T polymorphism and RA susceptibility, and odds ratio (OR) and 95% confidential interval (CI) were calculated under different genetic models. Then heterogeneity, stratified analysis, and publication bias test were conducted in the study.
RESULTSA total of 32 studies (40 separate comparisons) with 25 059 RA patients and 25 466 controls were included in this meta-analysis. No evidence for publication bias was found in these studies. Meta-analysis showed an association between PTPN22 1858C/T polymorphism and RA (OR=1.606, 95%CI: 1.518-1.699, P<0.001). When stratified by ethnicity, T allele of PTPN22 1858C/T polymorphism was a risk allele in Caucasian (OR=1.612, 95%CI: 1.544-1.683, P<0.001); however, the polymorphism was not detected in Asians (or allele frequencies was extremely low). PTPN22 1858C/T polymorphism was associated with rheumatoid factor (RF) and anti-cyclic citrullinated peptide antibody (ACCP).
CONCLUSIONT allele of PTPN22 1858C/T polymorphism is associated with RA susaptibility in Caucasians. PTPN22 1858C/T polymorphism is significantly more prevalent in RF-positive or ACCP-positive patients than in RF-negative or ACCP-negative patients.
