MBTD1 and endometrioid stromal sarcoma: In fact, endometrial stromal nodules and low-grade endometrial stromal sarcomas show typical gene translocations, including JAZF1-SUZ12 t(7;17)(p15;q21) fusion (in 50% of cases), JAZF1-PHF1 t(6;7)(p21;p15) (in 6% of cases), EPC1-PHF1 t(10;17)(q22;p13) (in 4% of cases), MEAF6-PHF1 t(1;6)(p34;p21) (in 3% of cases), and MBTD1-Cxorf67 t(X;17)(p11.2;q21.33) (in 2% of cases) [15,27,28].
