Tumor necrosis factor‐α polymorphism and risk of primary nephrotic syndrome: A case–control study and meta‐analysis

Abstract

BackgroundThe current study aims to explore the relationship between tumor necrosis factor‐α (TNF‐α) polymorphism and the risk of primary nephrotic syndrome (PNS).MethodsA 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.ResultsNo 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).ConclusionsTNF‐α rs1800629 polymorphism does not appear to confer any increased risk for PNS.
