Ovarian cancers often lack tumour-specific antigens, but there are several tumour-associated antigenic targets, including erb-b2 receptor tyrosine kinase 2 (ERBB2), programmed cell death-ligand, anti-Müllerian hormone receptor type 2 (AMHR2), and MUC16[176-179]. The gene discussed is ERBB2; the disease is ovarian cancer.
