Several other ‘DTC-specific’ genes in this panel (PDGFRB, STEAP1, SRC, WNT5A, PTCH1), although not necessarily prognostic in this study, could also serve as potential therapeutic targets, even if they have proven less effective targets for the treatment of primary breast tumors in otherwise unselected patient population [24, 25]. The gene discussed is WNT5A; the disease is breast neoplasm.
