Recent epidemiologic studies suggest that common polymorphisms of methylenetetrahydrofolate reductase (MTHFR) with allele frequencies up to 35% in the general North American population may modulate cancer risk. In some cancers, folate and other nutrients involved in the MTHFR metabolic pathway appear to interact with MTHFR polymorphisms to further modify cancer risk. In carcinogenesis, MTHFR polymorphisms thus provide a paradigm of gene-nutrient interactions, an emerging and important topic in the field of nutrition and cancer. Furthermore, MTHFR polymorphisms and MTHFR-nutrient interactions provide an opportunity to identify an ideal target group of individuals, at high risk of developing cancer, for rational, effective, and safe chemoprevention using these nutrients.
