APOBEC3A and neoplasm: For instance, the publicly available RADAR database catalogues A>I RNA editing sites with manual annotations, and this tool has been used alongside data from The Cancer Genome Atlas to identify protein variants that may affect tumor cell viability and drug sensitivity.19,20 Although at least one study attempted to collate known APOBEC3A/G editing sites, no comprehensive database like RADAR yet exists for C>U editing events, and studies on APOBEC3 editing tend to remain narrowly focused on one or two diseases at a time.9
