In order to investigate the influence of functional polymorphisms of macrophage migration inhibitory factor(MIF),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 MIF-173(G/C)(rs755622),FCGR2A-131H/R(rs1801274) and FCGR3A-158V/F(rs396991) was carried out using TaqMan SNP Genotyping Assay method.We found a statistically significant increase of the MIF-173CC homozygote genotype and MIF-173C 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 MIF-173C variant may play an important role in the development of active tuberculosis.

The genotyping for MIF-173 (G / C) (rs755622), FCGR2A-131H / R (rs1801274) and FCGR3A- 158V / F (rs396991) was carried out using TaqMan SNP Genotyping Assay method significant increase of the MIF-173CC homozygote genotype and MIF-173C 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.
