Using a case-control design, we analyzed associations between BC risk and the following SNPs: rs832583 (MAP3K1), rs16865677 (SF3B1), rs3819122 (SMAD4), rs12456284 (SMAD4), rs75704921 (ARID2), rs2229032 (ATR), rs3735156 (KMT2C), rs2276738 (MAP3K13), rs2293206 (MAP3K13), rs4075943 (MAP3K13), rs13091808 (MAP3K13), rs178831 (NCOR1), and rs3759173 (TBX3). Here, MAP3K1 is linked to breast cancer.
