FOXP3 rs2280883 polymorphism confers susceptibility to colorectal cancer in a Chinese Han population.

Studies imply the FOXP3 gene polymorphisms are engaged in the occurrence of some cancers, but the relationship between FOXP3 rs2280883 polymorphism and the hazard of colorectal cancer (CRC) is unclear. For this reason, a case-control investigation involving 365 CRC patients and 411 healthy individuals (matched by both age and gender) was taken to illustrate the underlying association. FOXP3 rs2280883 polymorphism genotyped via PCR-RELP. Data revealed this polymorphism was significantly linked to increased risk for CRC (CC versus TT, OR, 1.75; 95%CI, 1.06-2.88; P = 0.030). Subgroup analyses uncovered FOXP3 rs2280883 polymorphism intensified the risk of CRC among smokers. As for the connection between rs2280883 and clinical data of CRC, this polymorphism corelated to lymph node metastasis (CC versus TT: OR, 2.75; 95%CI, 1.35-5.62; P = 0.004) and the TNM stage. In conclusion, FOXP3 rs2280883 polymorphism is related to higher risk of CRC in a Chinese individuals. Larger-sized studies involving other races are needed.
