Abstract
The objective of the study was to determine by meta-analysis whether polymorphisms of the gene encoding peptidylarginine deiminase 4 (PADI4) are associated with susceptibility to rheumatoid arthritis (RA). A literature review was conducted to identify data sets that described analyses of genetic association between PADI4 polymorphisms and RA. Data sets were collated and a meta-analysis was performed, with a specific focus on associations within Caucasian and Asian populations. A total of 15,947 RA cases and 22,696 controls that were taken from 28 studies in 24 papers were included in this study. Meta-analysis showed a significant association between allele 2 of the PADI4_94 polymorphism and RA in the overall population (odds ratio [OR] = 1.155, 95 % confidence interval [CI] = 1.069-1.249, p = 2.7 x 10(-5)). Stratification by ethnicity revealed an association between PADI4_94 allele 2 and RA in Asians (OR = 1.273, 95 % CI = 1.193-1.359, p ˂ 1.0 x 10(-9)), but not in Caucasians (OR = 1.024, 95 % CI = 0.973-1.078, p = 0.358). However, meta-analysis using homozygote contrast showed an association between PADI4_94 allele 2 and RA in both Asians (OR = 2.311, 95 % CI = 1.1.858-2.875, p ˂ 1.0 x 10(-9)) and Caucasians (OR = 1.523, 95 % CI = 1.157-2.004, p = 0.008). Meta-analysis also revealed an association between allele 2 of the PADI4_104 polymorphism and RA in both Asians (OR = 1.547, 95 % CI = 1.247-1.919, p = 7.1 x 10(-6)) and Caucasians (OR = 1.096, 95 % CI = 1.025-1.172, p = 0.008). Finally, meta-analysis showed an association between allele 2 of the PADI4_92 polymorphism and RA in Asians (OR = 1.263, 95 % CI = 1.153-1.384, p = 5.8 x 10(-8)), but not in Caucasians (OR = 1.123, 95 % CI = 0.980-1.287, p = 0.095). Meta-analysis indicated no association between allele 2 of either the PADI4_90 or PADI4_89 polymorphisms and RA in Asians. This meta-analysis revealed that the PADI4_94 and PADI_104 polymorphisms are associated with susceptibility to RA in Asians and Caucasians, and that the PADI4_92 polymorphism is associated with susceptibility to RA in Asians, but not in Caucasians.
