We also found that six corresponding genes of eight m6A-SNPs were differentially expressed in breast cancer, and the SNPs rs4829 and rs9610915 were located next to the m6A modification site in the 3ʹUTR of TOM1L1 and MAFF, respectively, suggesting that these two SNPs may affect the m6A modification site and regulate gene expression to play a role in breast cancer. The gene discussed is MAFF; the disease is breast cancer.
