Objective:
The association of the IL-17A rs2275913 polymorphism with the risk of colorectal cancer (CRC) has been previously reported. However, the results are inconsistent. In this study, we comprehensively assessed the effect of the rs2275913 polymorphism on CRC risk.
Methods:
The rs2275913 polymorphism of 208 CRC patients and 312 age- and gender-matched healthy controls was genotyped by the polymerase chain reaction-restriction fragment length polymorphism method, and then analyzed by logistic regression. In addition, a pooled analysis based on five single-center studies was performed using Stata 12.0 software.
Results:
Logistic regression analysis indicated that the IL-17A rs2275913 polymorphism was associated with CRC risk (GA vs. GG: OR = 1.53, 95% CI = 1.02-2.28; AA vs. GG: OR = 1.89, 95% CI = 1.11-3.20; GA+AA vs. GG: OR = 1.62, 95% CI = 1.11-2.37; A vs. G: OR = 1.38, 95% CI = 1.07-1.77). Further pooled analysis also indicated a statistically significant association between the rs2275913 polymorphism and CRC risk in Asians and Northern Africans.
Conclusion:
This study suggested that the IL-17A rs2275913 polymorphism may act as a biomarker for predicting CRC risk. However, further functional research should be performed to clarify the role of the rs2275913 polymorphism in the etiology of CRC.
