Title: Association of the Nramp1 gene polymorphisms and clinical forms in patients with tuberculosis

Abstract: Background: Recent studies have reported that Nramp1 polymorphisms might have an important role in the development of tuberculosis in various populations. In this study, we aimed to determine Nramp1 polymorphisms in our patients with tuberculosis population.
Methods: We enrolled 127 patients with active tuberculosis and 116 healthy adults with similar age and gender. Peripheral blood samples were taken for determining the Nramp1 polymorphisms. By using Polymerase Chain Reaction (PCR) – Restriction Fragment Length Polymorphisms (RFLP) technique, we evaluated the polymorphisms of Nramp1 at the regions of D543N and INT4.
Results: We found that the Nramp1 polymorphisms at the region of D543N (OR: 0.44, 95%CI: 0.09–2.06 for GA allele) were not a risk factor for tuberculosis. Furthermore, we could not able to detect Nramp1 polymorphism at the regions of INT4 (OR: 0.97, 95%CI: 0.55–1.72 for GC allele and OR: 0.90, 95%CI: 0.21–3.77 for CC allele).
Conclusion: The findings of the present study do not support the hypothesis that Nramp1 at the regions of D543 and INT4 might play a role in influencing the growth of bacilli and progression of cavitary tuberculosis rather than susceptibility to M. tuberculosis infection. Future studies are needed to elucidate the role of Nramp1 variants in the pathogenesis of tuberculosis (Tab. 3, Ref. 29).
