Objective:
To investigate the association of 1858C/T polymorphism of protein tyrosine phosphatase nonreceptor type 22 (PTPN22) and rheumatoid arthritis (RA) susceptibility.
Methods:
CMB, 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.
Results:
A 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).
Conclusion:
T 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.
