The frequency of heterozygous (Ins/del) genotypes for TLR2 (−196 to −174) polymorphism was predominant in XDR-TB patients (0.57), whereas heterozygous A/G genotype for TLR1 743 A > G single nucleotide polymorphism (SNP) was predominant in healthy controls (0.57) for TLR1 743 A > G gene polymorphism. The gene discussed is TLR1; the disease is tuberculosis.
