The risk of colorectal cancer (CRC) is influence by polymorphisms located in the genes encoding enzymes of the folate pathway. The aim of this study was to evaluate if 2R/3R TS (rs34743033) polymorphism is involved in predisposition for colorectal in Romanian subjects. In the present case-control study, 75 sporadic CRC subjects and 60 healthy controls were genotyped by PCR method. The frequency of 3R/3R genotype was 40% in control group and 42.7% in cancer group. We found that there was no statistically significant association between the risk for CRC and 2R/3R TS polymorphism in Romanian subjects.
