  Tuberculosis (TB), caused by Mycobacterium tuberculosis, is worldwide and keeps on increasing with the appearance of HIV. Host genes involved in the immune response play key role in conveying resistance or susceptibility to TB. We investigated a possible association of the different single nucleotide polymorphisms (SNPs) present in the promoter region of the TNF with either susceptibility or resistance TB. Nucleotide sequencing of the promoter region of TNF encompassing the SNPs –238 G/A, –308 G/A, –857 C/T, –863 A/C and –1031 T/C was performed on 230 TB patients and 293 control subjects. The –863 A/C and –857 C/C genotypes show protection to TB. The –308A allele is associated with protection to TB. Haplotypes analysis revealed that the haplotype –1031T/– 863C/–857C/–308A/–238G is protective to TB (.. View More»
