Meta-analysis of the TNF-α-308G/A polymorphism and vitiligo risk
Several case-control studies have been conducted to investigate the association between the tumor necrosis factor-α (TNF-α)-308G/A polymorphism and vitiligo risk. However, the results of these studies are inconsistent; therefore, we attempted to comprehensively evaluate the association between TNF-α-308G/A polymorphism and vitiligo risk via a meta-analysis. Studies reporting the association between TNF-α-308G/A polymorphism and vitiligo risk were retrieved from PubMed and EmBase databases.
