Ye et al. analyzed 12 SNPs in the DNMT1 gene (rs2116940, rs2336691, rs7253062, rs16999593, rs6511685, rs6511677, rs8101866, rs2241531, rs10418707, rs10407514, rs4804122, rs11085587), but they did not find any apparent association of DNMT1 mutation with the risk of breast cancer among Chinese women[35]. This evidence concerns the gene DNMT1 and breast cancer.
