Background and purpose: 

The present study aimed at evaluating the possible association between CD209 rs4804803 (–336 A/G) gene polymorphism and pulmonary tuberculosis (PTB) in a sample of Iranian population. 



This case–control study was performed on 156 PTB patients and 154 healthy individuals. Tetra-amplification refractory mutation system-polymerase chain reaction was used to detect the polymorphisms.



Our findings revealed that the CD209 rs4804803 increased the risk of PTB in codominant [odds ratio (OR) = 5.16, 95% confidence interval (CI) = 1.60–16.59, p = 0.006, GG vs. AA], dominant (OR = 1.69, 95% CI = 1.07–2.66, p = 0.024, AG + GG vs. AA), and recessive (OR = 4.20, 95% CI = 1.34–13.16, p = 0.014, GG vs. AA + AG) tested inheritance models. Furthermore, the rs4804803 G allele increased the risk of PTB (OR = 1.58, 95% CI = 1.12–2.23, p = 0.011) as compared to the A allele. 



Our data suggest that CD209 rs4804803 polymorphism increased the risk of PTB in a sample of Iranian population.
