Four loci were identified that exhibited consistent association with breast cancer and contain plausible causative genes [31]: fibroblast growth factor receptor 2 (FGFR2); TOX high mobility group box family member 3 (TNRC9); mitogen-activated protein kinase kinase kinase 1 (MAP3K1); and lymphocyte-specific protein 1 (LSP1). Here, LSP1 is linked to breast carcinoma.
