Additionally, several studies have confirmed that UTROSCT lacks the characteristic JAZF-1-SUZ12 gene fusion [7] or PHF1 gene rearrangement [8] of endometrial stromal tumors and does not have the FOXL2 and DICER1 gene mutations unique to ovarian sex cord stromal tumors [9]. The gene discussed is DICER1; the disease is endometrial stromal tumor.
