In human disease, BCAS3 was found to be overexpressed in breast cancer3 (hence, the previous gene name, breast carcinoma-amplified sequence 3), and high levels of BCAS3 were noted in tumor cells and blood vessels of different brain tumors, such as glioblastoma and hemangiopericytoma, as well as in brain abscesses.1 The gene discussed is BCAS3; the disease is glioblastoma.
