| Abstract: | BACKGROUND AND AIMS: In one small study, the DCC Arg201Gly polymorphism has been observed more frequently in colorectal cancer cases compared with controls. We wondered whether these results could be replicated in a much larger study. METHODOLOGY: The DCC Arg201 Gly polymorphism was genotyped in 625 unselected Caucasian colorectal cancer patients and 220 controls. Association analysis was used to search for a difference between patients and controls. Subgroup analyses were performed for site of tumour, gender, age at diagnosis, family history of colorectal cancer and modified Dukes classification. RESULTS: The association analyses revealed no difference in Arg201Gly genotype frequency between patients and controls, neither overall nor for different subgroups according to site of tumour, gender, age at diagnosis, family history of colorectal cancer and modified Dukes classification. CONCLUSION: No association was observed between the Arg201Gly polymorphism of DCC and colorectal cancer risk. |
