Background:Mycobacterium tuberculosis infects nearly 1/3 of the world population and this reservoir forms the largest pool from which new cases arise. Among the cytokines, IFN-gamma is a key determinant in protection against tuberculosis. Single nucleotide polymorphisms (SNPs) in IFN-gamma gene (+874 T/A) which determine TT high ((hi)), AA low ((lo)) and TA intermediate ((int)) responder phenotypes have shown variable associations with tuberculosis disease outcome in different ethnic populations. The objective of the current study was to analyze IFN-gamma gene combinations with other IFN-gamma regulating cytokine genes (IL-10, TNF -alpha, IL-6) to see the effect of gene- combinations on disease …
