The objectives of this study was to evaluate a potential role for natural-resistance-associated macrophage protein 1 (NRAMP1) gene in the human homologue using four single base pair polymorphisms (D543N, 3’UTR, INT4, 274C/T) for susceptibility to tuberculosis infection in Surabaya, Indonesia. The study population were 69 lung tuberculosis patients and 43 healthy nurses were genotyped with the polymerase chain reaction (PCR) and the product amplified from their genomic DNA were subjected to restriction enzyme digestion (RFLP) and were analysed using agarose gel electrophoresis. Results of this study showed only the homozygous TGTG deletion allele at the 3’untranslated region (3’UTR) of the NRAMP1 gene i.e. the TGTGdel/del genotype was more frequently found in lung tuberculosis patients (20/69=29%) compared to that found in nurses (2/43=4.7%). The Odds ratios (ORs) were 8.37 (95% confidence interval [CI], 1.85 to 37.94; p=0.002). This finding shows that polymorphism 3’UTR of NRAMP1 gene increased the risk of lung tuberculosis in Surabaya, Indonesia.

Background: Natural resistance associated macrophage protein 1 (Nramp1) is a relatively conservative gene that plays a crucial role in swine immune response and disease resistance. Methods: We identified the polymorphisms and gene variations in the exon 2 of Nramp1 using polymerase chain reaction–restriction fragment length polymorphism and investigated the correlation between the polymorphisms and piglet diarrhea in four pig breeds (Bamei, Duroc, Landrace, and Large White pigs). Result: The results showed that two alleles (A and B) were identified in all the pig breeds, three genotypes (AA, BB, and AB) were detected in Bamei and Large White breeds, and two genotypes (AA and AB) were detected in Landrace and Duroc breeds. Allele A and genotype AB were dominant in Bamei, Large White, and Landrace breeds, whereas genotype AA was dominant in Duroc pigs. A moderate polymorphism was observed in Landrace and Large White pigs, and polymorphism was abundant in Bamei pigs and low in Duroc pigs. The Chi-square test for Hardy–Weinberg equilibrium disclosed that the exon 2 of Nramp1 in the four breeds of pigs did not deviate from the Hardy–Weinberg balance (P less than 0.05). The results of association analysis showed a significant correlation between breed and piglet diarrhea (P less than 0.05), and the diarrhea score of Bamei pigs was much lower than those of the other breeds. The study could supply theoretical references for further functional research on Nramp1 gene and for screening genes related to disease-resistance breeding.
