As shown in Figure 8A, ETV4 was significantly associated with MMR genes in 26 tumors (notably, it was not associated with MMR genes in acute myeloid leukemia, ovarian serous cystadenocarcinoma, PRAD, READ, thymoma, uterine carcinosarcoma, and uveal melanoma). The gene discussed is ETV4; the disease is ovarian serous cystadenocarcinoma.
