Abstract:
BACKGROUND:Limited studies have focused on the association between the protein tyrosine phosphates non-receptor type 22 (PTPN22) genetic polymorphisms and Juvenile idiopathic arthritis (JIA) susceptibility in different populations, but the results were inconclusive. Therefore, this meta-analysis of PTPN22 polymorphism (1858 C>T) was performed to get a precise systematic estimation. The "rs" number of the PTPN22 polymorphism (1858 C>T) is 4. METHODS:A systematic literature search strategy was carried out using English databases (PubMed, Embase.) for the eligible studies. We ultimately identified 11 records from 10 articles involving the relationship between PTPN22 genetic polymorphisms and JIA risk from PubMed and Embase databases. Overall, 4552 cases and 10161 controls were investigated in this study to evaluate the association between PTPN22 (C allele vs. T allele) genotype and JIA susceptibility. RESULTS:Analysis using random effects model showed an increased risk of JIA with T allele of rs2476601 vs. A allele (P<0.001). Subgroup analysis suggested that the PTPN22 polymorphism (1858C>T) was significantly associated with JIA risk in America population (OR=1.52, 95% CI:1.30-1.78). Additionally, the subgroup analysis also showed that the associations were still significant in case number more than 500 (OR=1.38, 95% CI: 1.04-1.83), while in the case number less than 500 was OR=1.55, 95% CI: 1.39-1.72. CONCLUSIONS:SNPs of PTPN22 (1858C>T) showed an increased risk of developing JIA.
