Furthermore, basal-like breast tumors have elevated expression of CK5, CK14, caveolin-1, caix, p63, and EGFR (epidermal growth factor receptor)/HER1; and the reduced expression of ER, PR, and HER2 impacts the basal/myoepithelial cell component of the mammary gland. The gene discussed is EGFR; the disease is breast neoplasm.
