In order to investigate the influence of functional polymorphisms of macrophage migration inhibitory factor （M/F）, Fcg receptors CD16A （FCGR3A） and CD32A （FCGR2A） genes on susceptibility to pulmonary tuberculosis （PTB） in the Moroccan population, we analyzed 123 patients with PTB and 154 healthy controls. 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.
