FANCD2 and glioblastoma: Aberrantly expressed analysis from TCGA data revealed that FANCD2 was differentially expressed in many human tumor tissues, and that FANCD2 mRNA overexpression was found in BLCA, BRCA, CHOL, COAD, ESCA, GBM, HNSC, KIRC, KIRP, HCC, LUSC, PRAD, THCA, and UCEC, whereas FANCD2 loss was found in KICH (Figure 2A).
