A new annotation on the hg18 human assembly, ORFeome Clones, shows alignments of human clones from the ORFeome Collaboration (http://www.orfeomecollaboration.org/) (34), a project that aims to be an unrestricted source of fully sequence-validated full-ORF human cDNA clones, with the goal of providing at least one fully sequenced full-ORF clone for each human gene. This annotation is automatically updated daily as new clones become available.
