Abstract
OBJECTIVE
To evaluate the possible association between cathepsin Z (CTSZ) rs34069356 C/T (Ala286Thr) and melanocortin-3 receptor (MC3R) rs6127698 G>T (-484 G/T) gene polymorphisms and pulmonary tuberculosis (PTB) in an Iranian sample population.
DESIGN
This case-control study included 150 PTB patients and 177 healthy subjects. Tetra amplification refractory mutation system-polymerase chain reaction was used to detect polymorphisms.
RESULTS
Our findings revealed that the MC3R rs6127698 TT genotype increased the risk of PTB compared with GG (additive model: OR 2.24, 95%CI 1.13-4.64, P = 0.021) as well as GG+GT (recessive model: OR 1.89, 95%CI 1.13-3.18, P = 0.016). The rs6127698 T allele increased the risk of PTB (OR 1.56, 95%CI 1.14-2.13, P = 0.005) compared to the G allele. The CTSZ rs34069356 polymorphism was not associated with PTB in additive-, dominant- and recessive-tested inheritance models (P > 0.05).
CONCLUSION
Our data suggest that MC3R rs6127698, but not CTSZ rs34069356 polymorphism, is associated with PTB in a sample Iranian population.
