Background:
The current study aims to explore the relationship between tumor necrosis factor-α (TNF-α) polymorphism and the risk of primary nephrotic syndrome (PNS).
Methods:
A total of 250 PNS patients were selected for this study, as well as 300 volunteers serving as the control group. TNF-α polymorphism were assessed using the polymerase chain reaction-restriction fragment length polymorphism method. In addition, a meta-analysis was conducted to analyze previously published literature on this topic.
Results:
No significant differences were observed in the genotypes frequency or alleles frequency among the study populations. Meta-analysis results revealed a positive association between TNF-α rs1800629 polymorphism and allele contrast in African populations (p = 0), homozygote comparison (p = .007), heterozygote comparison (p = .026), recessive genetic model (p = .011), and dominant genetic model (p = .000).
Conclusions:
TNF-α rs1800629 polymorphism does not appear to confer any increased risk for PNS.
