All current CCDS IDs are now identified on the full report page as being either Reviewed or Provisional, depending on whether they have been reviewed by the RefSeq, Havana or CCDS collaboration groups. A Reviewed status indicates that the CCDS ID has undergone a review by both individual annotation groups (RefSeq and Havana), or jointly by all members of the CCDS collaboration, or a combination of these options. A Provisional status indicates that the CCDS ID has not been reviewed to that extent.
