NR4A1 and breast cancer: Five genes were associated with BC risk: TBX3 (rs2242442) was associated with decreased risk; TTN (10497520) and MAP3K1 (rs702688 and rs72758040) were associated with increased risk; MLL2 (rs11168827) was associated with increased overall risk, positive hormone receptor status, and low-grade tumors; and SF3B1 (rs4688) had a protective effect and was associated with negative lymph node findings, metastasis, and hormone receptor status [11].
