0.100 GeneticVariation BEFREE The presence of MTR A2756G mutant allele and MTHFR C677T mutant allele in carriers was associated with increased breast cancer risk [odds ration, 3.2 (P=0.16; 95% confidence interval, 0.76-13.9) and 3.9 (P=0.09; 95% confidence interval, 0.93-16.3), respectively]. 18842997 2008
Malignant neoplasm of breast
CUI: C0006142
Disease: Malignant neoplasm of breast
0.100 GeneticVariation BEFREE Based on the hypothesis that variants of the cSHMT C1420T together with methionine synthase (MS A2756G) and 5,10-methylenetetrahydrofolate reductase (MTHFR C677T and A1298C) are associated with breast cancer, we performed a multigenic case-control study of the effects to breast cancer risk of four polymorphisms of folate-metabolizing genes against duration of estrogen exposure. 17896178 2008
Malignant neoplasm of breast
CUI: C0006142
Disease: Malignant neoplasm of breast
0.100 GeneticVariation BEFREE We evaluated case-control association of MTHFR C677T, A1298C, and MTR A2756G polymorphisms for cases strata-defined by promoter methylation status for each of three genes, E-cadherin, p16, and RAR-beta2 in breast cancer; in addition, we evaluated case-case comparisons of the likelihood of promoter methylation in relation to genotypes using a population-based case-control study conducted in Western New York State. 19240236 2009
Malignant neoplasm of breast
CUI: C0006142
Disease: Malignant neoplasm of breast
0.100 GeneticVariation BEFREE We investigated the association of polymorphisms in MTHFR (rs1801133 and rs1801131) and MTR (rs1805087) with breast cancer risk and their interaction with alcohol consumption in a case-control study--the Western New York Exposures and Breast Cancer study. 19706843 2009
Malignant neoplasm of breast
CUI: C0006142
Disease: Malignant neoplasm of breast
0.100 GeneticVariation BEFREE Taken together, the results suggest that the MTR A2756G polymorphism may contribute to susceptibility to breast cancer among Europeans. 20111902 2010
Malignant neoplasm of breast
CUI: C0006142
Disease: Malignant neoplasm of breast
0.100 GeneticVariation BEFREE This study points out the importance of the interactions between the MTHFR C677T, MTHFR A1298C and MTR A2756G polymorphisms, and also highlights the relevance of the MTR A2756G polymorphism and age in breast cancer risk. 23155246 2012
Malignant neoplasm of breast
CUI: C0006142
Disease: Malignant neoplasm of breast
0.100 GeneticVariation BEFREE In this case-control study, we investigated the association between MTHFR C677T and A1298C, TYMS 5'-UTR, MTR A2756G and cSHMT C1420T and also the folate carrier (RFC1 G80A) and breast cancer risk in a northeastern Brazilian population. 22134752 2012
Malignant neoplasm of breast
CUI: C0006142
Disease: Malignant neoplasm of breast
0.100 GeneticVariation BEFREE In conclusion, the findings suggest that MTR A2756G polymorphism is not associated with altered susceptibility to breast cancer, while the observed decreased risk in Caucasians, PB subgroup, and large studies and increased risk in small studies may be due to selection bias or other unknown factors. 23845785 2013
Malignant neoplasm of breast
CUI: C0006142
Disease: Malignant neoplasm of breast
0.100 GeneticVariation BEFREE We did not find a significant effect of the MTHFR A1298C and MTR A2756G on the risk of breast cancer. 25366783 2014
