Abstract

Objective: The aim of this study was to determine whether the p53 codon 72 polymorphism confers susceptibility to systemic lupus erythematous (SLE) and rheumatoid arthritis (RA). Methods: A meta-analysis was conducted on the associations between the p53 codon 72 polymorphism and SLE or RA using: 1) allele contrast; 2) the recessive model; 3) the dominant model; and 4) the additive model. Results: A total of 10 studies, that is, 6 SLE and 4 RA studies, involving 1578 patients and 3138 controls were considered in the meta-analysis. Meta-analysis of the p53 codon 72 polymorphism showed no association between patients and the C allele (odds ratio (OR) = 0.834, 95% confidence interval (CI) = 0.599-1.161, p = 0.282), or between SLE and the p53 C allele (OR = 0.998, 95% CI = 0.765-1.302, p = 0.989). However, stratification by ethnicity showed an association between the p53 C allele and SLE in Asians (OR = 1.410, 95% CI = 1.044-1.906, p = 0.025), but not in Europeans (OR = 0.871, 95% CI = 0.625-1.214, p = 0.415). Furthermore, an association was found between the polymorphism and SLE in Asians using recessive and additive models. However, no association was found between RA and the p53 codon 72 polymorphism in all study subjects or in Europeans. Conclusions: This meta-analysis demonstrates that the p53 codon 72 polymorphism may confer susceptibility to SLE in Asians, but not in Europeans.
