Background:
We studied the association between iron intake and polymorphisms in the iron transporter gene SLC40A1 and the risk of tuberculosis.
Methods:
We compared iron intake, the frequency of SLC40A1 mutations, and interactions among these variables among 98 tuberculosis patients and 125 controls in Kwazulu-Natal, South Africa.
Results:
Four SLC40A1 single-nucleotide polymorphisms (SNPs) were associated with an increased risk of tuberculosis and 1 SNP with reduced risk. We also found a gene-environment interaction for 4 nonexonic SNPs and iron intake.
Conclusions:
This pilot study demonstrated an association between polymorphisms in SLC40A1 and tuberculosis and provided evidence of an interaction between dietary iron and SLC40A1.

Translation
Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following transcription, it constitutes the final step in the expression of genes. This process is carried out by ribosomes, complexes of protein and specialized RNA molecules. Ribosomes, transfer RNA (tRNA), and other proteins produce a chain of amino acids—the polypeptide—as the end product of translation.
