FANCB and glioblastoma: Tumors bearing amplification of FA pathway genes (FANCB, FANCC and FANCM in LGG and UBE2T in GBM) and HDR genes (ATM, CHECK1, MRE11A in GBM and GEN1 in skin cutaneous melanoma [SKCM]) showed significantly reduced temozolomide-induced signature score (Figure 2G), indicating the critical role of DSB-associated recombinational repair in attenuating alkylating agent-induced genome lesions 30,31.
