FANCD2 and glioblastoma: This result indicated that FANCD2 mRNA expression in BLCA, BRCA, CHOL, COAD, GBM, HCC, LUSC, READ, STAD, and UCEC was also high (Figures 2B–K), suggesting that FANCD2 acts as an oncogene in multiple tumors, which was also verified by the HCCDB (Supplementary Figure S1A and Table 1).
