Hi Paul > Can anyone recommend a way to derive a list of oncogenes (even an inexact list) from the annotation > packages, org.Hs.eg or something else? > > Thanks. > > - Paul As far as I am aware of this is not currently possible. You could look up "oncogene" at the NCBI Gene site and save the result as a list of Entrez Gene IDs (UID) which can easily be integrated with the BioC annotation packages for further analysis.
