Systemic Lupus Erythematosus (SLE) is an autoimmune disorder characterized by autoantibody production and organ involvement. The role of toll-like receptor-7 in SLE is well established. Although genetic variations in the TLR-7 gene have been associated with an increased risk of developing SLE, the findings are not consistent. We performed a meta-analysis of previously published articles on four important single nucleotide polymorphisms in the TLR-7 gene (rs3853839, rs179008, rs179019, and rs179010) to reach a valid conclusion. Various literature databases, including PubMed, Science Direct, and Scopus, were scoured for eligible reports until May 10, 2023. GPower software v.3 was used to assess the power of individual reports included in the meta-analysis. Comprehensive Meta-analysis v3 software was used to perform all statistics. The publication biases in each genetic comparison model were investigated using funnel plots and Egger's regression test. To test heterogeneity, Cochrane Q statistics, probability value and I2 were used. Considering the predefined inclusion and exclusion criteria, the current study included a total of 10 eligible studies that included 15,472 SLE cases and 16,721 healthy controls. The meta-analysis revealed a significant association between TLR7 polymorphisms (rs179019 and rs179010) and susceptibility to SLE development. Other TLR7 polymorphisms (rs3853839 and rs179008), on the other hand, showed no significant association. Furthermore, the trial sequential analysis identified the need for additional case control studies for TLR-7 polymorphisms (rs3853839, rs179008, and rs179019) other than the rs179010 polymorphism. TLR7 variants for rs179010 and rs179019 are risk factor for the development of SLE. Further investigations are required to reach a valid conclusion. [ABSTRACT FROM AUTHOR] |
