Polymorphisms of Tuberculosis Susceptibility Candidate Genes in the Slavonic Population of Siberia: A Pilot Study

The 469+14 G/C (INT4), 1465-85 G/A, and C274T polymorphisms of NRAMP1 and the A/C polymorphism of IL12 3"UTR were analyzed in ethnic Russians with (N = 58) or without (N = 127) tuberculosis (TB) from Tomsk. On evidence of allele and genotype frequencies, none of the polymorphisms was associated with TB. In the healthy controls, the three NRAMP1 polymorphisms were in linkage disequilibrium with each other (p < 0.001) but not with the IL12 polymorphism. Still the four polymorphisms are potentially informative as concerns their association with TB.
