To evaluate the C677T and A1298C functional polymorphisms in the MTHFR gene and their associations with breast cancer risk, as well as the potential modifying effect by plasma folate status on the MTHFR-associated risk, a hospital-based case-control study was conducted on a Taiwanese population consisting of 146 histologically confirmed incident breast cancer cases and their 285 age-matched controls without a history of cancer.

In contrast, there was no statistically significant association between the risk of breast cancer and the MTHFR C677T genotype.

We investigated independent and joint effects of B vitamin intake as well as two polymorphisms of a key one-carbon metabolizing gene [i.e., methylenetetrahydrofolate reductase (MTHFR) 677C>T and 1298A>C] on breast cancer risk.

The common MTHFR C677T and TS enhancer region polymorphisms were not risk factors for breast cancer in this patient cohort nor were they associated with phenotypic features or with prognosis.

After adjusting for age of menarche, parity, alcohol intake and total fat intake we observed reductions in odds ratios for breast cancer risk comparing the highest with the lowest quartiles of serum folate concentrations of 0.23 (95% confidence interval (CI) 0.09, 0.54) for the entire group, 0.27 (CI 0.09, 0.80) for the wild-type and 0.08 (CI 0.01, 0.52) for the heterozygous C677T genotype.
