The lack of positive association of TNF-α -863(rs1800630) polymorphism in our study group implies that TNF-α -863 polymorphism is not a susceptible marker to RA and cannot serve as a genetic factor for screening RA patients in Pakistan.
Recent advances have highlighted a major genetic contribution to the pathogenesis of rheumatoid arthritis (RA).The aim of this study was to investigate whether polymorphisms of TNF-α (rs1800630, rs1800629) and TNFR1 (rs767455) were associated with susceptibility to and clinical outcome of RA in Chinese Han population.
Previous studies have investigated the association of TNF-α-238G/A (rs361525) and -308G/A (rs1800629) polymorphisms with rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE).
The aim of this study was to determine whether the TNF -1031T/C (rs1799964), -376G/A (rs1800750), -308G/A (rs1800629) -238G/A (rs361525), and TNFR1 -609G/T polymorphisms are associated with RA susceptibility in a sample of Mexican patients.
This study identifies a potentially important role for TNF-α rs1800629 polymorphisms in the susceptibility to RA.However, further studies in larger cohorts are required.
A long-term observational early RA inception cohort (n = 208) with detailed information about disease activity and radiologic damage after 3, 6 and 9 years of disease was genotyped for the TNFA -308G > A promoter polymorphism (rs1800629).
In this regard, besides a strong association between the HLA-DRB1∗04 shared epitope alleles and both endothelial dysfunction, an early step in the atherosclerotic process, and clinically evident CV disease, other polymorphisms belonging to genes implicated in inflammatory and metabolic pathways, located inside and outside the HLA region, such as the 308 variant (G > A, rs1800629) of the TNFA locus, the rs1801131 polymorphism (A > C; position + 1298) of the MTHFR locus, or a deletion of 32 base pairs on the CCR5 gene, seem to be associated with the risk of CV disease in patients with RA.
Evaluating the impact of cytokine SNPs in RA, we identified the G allele of rs1801275 in IL4R<i>α</i> (<i>p</i> = 0.043) and the G allele of rs361525 in TNF<i>α</i> (<i>p</i> = 0.005) as disease-associated risk factors in bivariate analyses.

The CT genotype and T allele of MTHFR C677 T and GG genotype and G allele of LT-α A252G are associated with the risk of RA and with higher levels of the pro-inflammatory cytokine, TNF-α in patients with rheumatoid arthritis.
