The Old UCSC Genes track shows genes from the previous version of the UCSC Genes build, which was built with GENCODE v32 models. See the description page for more information on how the new GENCODE v36 track was built.

The new release has 232,184 total transcripts, compared with 247,541 in the previous version. The total number of canonical genes has decreased from 66,622 to 60,675 . Comparing the new gene set with the previous version:

  • 221,698 transcripts did not change.
  • 20,017 transcripts were not carried forward to the new version.
  • 4,860 transcripts are "compatible" with those in the previous set, meaning that the two transcripts show consistent splicing. In most cases, the old and new transcripts differ in the lengths of their UTRs.
  • 966 transcripts overlap with those in the previous set, but do not show consistent splicing (i.e., they contain overlapping introns with differing splice sites)
