DICER1 and female reproductive system neoplasm: However, the identification of a DICER1 variant is not specific to Sertoli cell tumors, since such a variant has been reported in other gynecological neoplasms: in 63–80% of Sertoli–Leydig cell tumors, 40% of gynandroblastomas, 6% of juvenile granulosa cell tumors, but also in DICER1-associated sarcomas, and rare germ cell tumors (mixed malignant germ cell tumor, dysgerminoma, yolk sac tumor, and teratoma) [22,58,59,60,126,159,160,161].
