TLR2 and Guillain-Barre syndrome: It has been shown that genotypes of two polymorphic variants, Del/Del of rs111200466 insertion and deletion polymorphism of TLR2 gene and TT of rs3775290 single nucleotide polymorphism (SNP) of TLR3 gene, had significantly higher frequencies among GBS patients, while the frequencies of TT genotype of rs3804099 SNP of TLR2 gene and TT genotype of rs11536891 SNP of TLR4 gene were significantly higher in healthy subjects.
