TNF and Neonatal sepsis: In the homozygous gene model of TNF-α-308G/A (rs1800629) study, the P-values for Asian, European and global effects were 0.685, 0.169 and 0.171, respectively, which were all greater than 0.05, indicating that there was no correlation between TNF-α-308G/A (rs1800629) gene polymorphism and neonatal sepsis under the homozygous gene model.
