To this end, we and others have shown that anti-Müllerian hormone receptor type II (AMHR2) is expressed in 90% of primary EOCs, 78% of borderline malignancies, 77–86% of non-EOC ovarian tumors, and 56% of malignant ascites from grades III-IV ovarian cancers [8–11]. The gene discussed is AMHR2; the disease is ovarian carcinoma.
