The genotyping for M/F-173 （G/C） （rs755622）, FCGR2A- 131H/R （rs 1801274） and FCGR3A-158V/F （rs396991） was carried out using TaqMan SNP Genotyping Assay method. We found a statistically significant in- crease of the MIF-173CC homozygote genotype and M/F-173＂C allele frequencies in PTB patients compared with healthy controls （17.07% versus 5.84%, P = 0.003; and 35.37% versus 26.30%, P = 0.02; respectively）. In contrast, no association was observed between FCGR2A-131H/R and FCGR3A-158V/F polymorphisms and tuberculosis disease. Our finding suggests that M/F-173℃ variant may play an important role in the development of active tuberculosis.展开更多
