TLR3 and viral infectious disease: The studies that identified an association between the TLR3 rs5743305 T/A polymorphism and viral infections largely involved Caucasian populations (Grygorczuk et al., 2017; Fischer et al., 2018) and, consequently, genetically more homogeneous, while studies carried out in different population groups presented divergent results, as observed in the present study that evaluated a mixed-race population.
