ALKBH1 and neoplasm: Other functional probes were only associated with tumor classification, e.g. the gene encoding the Fanconi anemia complementation group M protein (FANCM) or the gene encoding the AlkB Homolog 1, Histone H2A Dioxygenase (ALKBH1). The former is involved in homology directed DNA repair, and the latter takes part in the repair of DNA alkylation damage and has recently been associated with the regulation of the level of N6-methyladenine (N6-mA) DNA modifications, implicated in epigenetic regulation of gene expression relevant in GBM [61].
