In addition to potential compounding genetic and/or epigenetic alterations within glioblastomas that might affect DDR‐targeting strategies, and the interplay within the BER, MMR, MGMT, FA and HR pathways (highlighted above), interactions between the FA pathway and other DDR elements have been characterised that are also important to consider with regard to potential FA‐based combination targeting strategies within glioblastomas [160]. Here, MRC1 is linked to glioblastoma.
