The TNFA-308G/A (rs1800629) and -238G/A (rs361525) polymorphisms are two widely investigated variants for their associations with risk of cervical cancer, but the results are conflicting.
Published data linking single nucleotide polymorphisms (SNPs) in the tumor necrosis factor-alpha (TNF-?) promoter region at positions -308G>A (rs1800629) and -238G>A (rs361525) to cervical cancer risk have been inconclusive.

Using high-resolution melting curve analysis, we investigated the prevalence of the TNF-α -308 G/A transition (rs1800629) in patients with cervical cancer (n = 362) and control subjects (n = 399).
There are no significant relationship between rs1800629 polymorphism and high risk HPV infection (OR = 0.649, 95% CI: 0.253-1.670, P = 0.371), cervical cancer (OR = 0.993, 95% CI: 0.376-2.618, P = 0.988), or cervical cancer with HPV infection (OR = 0.663, 95% CI: 0.250-1.758, P = 0.409).

We conducted a cross-sectional study to genotype 415 septic patients and 205 patients without sepsis for the SNPs -308(G/A) rs1800629 of TNF; +252 (G/A) rs909253 of LTA; -511(A/G) rs16944 and +3953(C/T) rs1143634 of IL1B; and -1082(A/G) rs1800896, -819(C/T) rs1800871 and -592(C/A) rs1800872 of IL10.
There are no significant relationship between rs1800629 polymorphism and high risk HPV infection (OR = 0.649, 95% CI: 0.253-1.670, P = 0.371), cervical cancer (OR = 0.993, 95% CI: 0.376-2.618, P = 0.988), or cervical cancer with HPV infection (OR = 0.663, 95% CI: 0.250-1.758, P = 0.409).
Our findings suggest that LTA rs909253 and TNF rs1800629 polymorphisms are associated with the risk of T1D both independently and in combination with polymorphic markers in other inflammatory genes, and the analysis of multi-allelic combinations provides valuable insight in the study of polygenic traits.
Of these variants, four were significantly associated with COPD susceptibility in random effects meta-analysis, the GSTM1 null variant (OR 1.45, CI 1.09-1.92), rs1800470 in TGFB1 (0.73, CI 0.64-0.83), rs1800629 in TNF (OR 1.19, CI 1.01-1.40) and rs1799896 in SOD3 (OR 1.97, CI 1.24-3.13).
Genetic variation of the TNFα rs1800629 might be useful as a biomarker in clinical decision-making since it was found to be related to cancer risk, tumor recurrence, and survival of H&N cancer patients.
The minor allele frequency of rs1800629 was significantly higher in severe sepsis patients than that in both healthy controls (P(adj) = 0.00046, odds ratio (OR)(adj) = 1.92) and sepsis patients (P(adj) = 0.002, OR(adj) = 1.56).
The goal of this study was to evaluate the influence that polymorphisms in the cytokine genes known as TNF-α-308 G/A (rs1800629), TNF-α-857 C/T (rs1799724), IL-8-251 T/A (rs4073), IL-8-845 T/C (rs2227532), and IL-10-592 C/A (rs1800872) have on changes to mRNA expression levels and on the risks of chronic gastritis (CG) and gastric cancer (GC).
A functional polymorphism, -308G>A (rs1800629), which is located in the promoter of TNFA gene, has been suggested to alter the production of TNF-α and influence cancer risk.
Initially, association with T1D was seen for LT-alpha A1069G (intron A, p=0.011, rs909253) and TNF G(-308)A (p<1x10(-5), rs1800629), but no association was observed for TNF G(-238)A (rs361525).
Genetic variation of the TNFα rs1800629 might be useful as a biomarker in clinical decision-making since it was found to be related to cancer risk, tumor recurrence, and survival of H&N cancer patients.
In contrast, the AA genotype carriers of the TNF-α rs1800629 has a significantly higher risk of developing COPD (OR = 1.83, 95%CI: (1.34-2.51), P < 0.00) compared to GG carrier.
The genotype distribution of SNPs in either rs1800629 or rs361525 did not significantly demonstrate higher frequency in the cancer group (p=0.621 and p=0.68, respectively).
In the present study, we aim to investigate the association of promoter-region polymorphisms IL-6 (-174G/C) rs1800795 and TNF-α (-308G/A) rs1800629 with pneumonia-induced sepsis.
A functional polymorphism, -308 G>A (rs1800629), which is located in the promoter of TNFA gene, has been suggested to alter the production of TNF-α and influence cancer risk.
