    Abstract:
    The results of the first Russian study of polymorphisms of tuberculosis (TB) susceptibility genes SLC11A1, VDR, IL12B, IL1B, IL1RN in Tuvinians from Tuva Republic and Russians from Tomsk city are presented. In Tuvinians, as compared with Russians, the significantly higher prevalence of potentially disease-associated alleles of the genes studied was shown: SLC11A1*543N (0.139 and 0.043, respectively, p = 4.6E-5), IL12B*1188C (0.378 and 0.174, respectively, p = 1.1E-8), VDR*b (0.825 and 0.532, respectively, p = 3.2E-16), IL1B*(+3953A1) (0.865 and 0.806, respectively, p = 0.035). However, no one of these alleles was associated with TB in Tuvinians, whereas, in Russians TB patients, in comparison with the controls, there was a higher prevalence of the following markers: IL1RN*A2 (0.258 and 0.186, respectively, p = 0.024), SLC11A1*274T (0.251 and 0.164, respectively, p = 0.009), IL12B*1188C (0.240 and 0.174, respectively, p = 0.044), ILIB*(+3953A2) (0.259 and 0.194, respectively, p = 0.044). Distinct patterns of linkage disequilibrium between pairs of the polymorphisms studied in Tuvinians and Russians were shown. At whole, the data obtained demonstrate the ethnic specificity of the distribution and pathogenetic significance of the alleles of the TB susceptibility genes.
