We investigated the supposed-2029C>T and 2258G>A TLR2 polymorphisms in 422 critically ill patients of European origin from southern Brazil (295 with sepsis and 127 without sepsis) and reviewed 33 studies on these polymorphisms, conducting a quality assessment with a score system.
Single nucleotide polymorphisms (SNPs) Arg753Gln and Arg677Trp affect TLR2 responsiveness and may contribute to the course of sepsis, which is associated with substantial morbidity and mortality during intensive care treatment.
