It has been documented that CD1A∗01/02 and CD1E∗01/02 genotypes, A(-670)G single nucleotide polymorphism in the promoter region of CD95, TNF-α308 G/A and 857 C/T polymorphisms, mannose-binding lectin H allele/HY promoter haplotype/HYA haplotype, macrophage mediators SNPs, TCR Vβ and Vδ genes, CD95 A(-670)G SNP, TLR 4 Asp299Gly polymorphism, killer-immunoglobulin-like receptor genotype, and glucocorticoid receptor genotype were related to GBS [28, 33–39]. This evidence concerns the gene TNF and Guillain-Barre syndrome.
