The Old UCSC Genes track shows genes from the previous version of
the UCSC Genes build. This is similar to the current version but
without explicitly including Rfam or tRNA sequences.
The new release has 82,960 total transcripts, compared with 80,922 in
the previous version. The total number of canonical genes has
increased from 31,227 to 31,848. Comparing the new gene set with the
- 74,657 transcripts did not change between versions.
- 88 transcripts were not carried forward to the new version.
- 5,556 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.
- 621 transcripts overlap with those in the previous set but do
not show consistent splicing, i.e., they contain overlapping introns
with differing splice sites.
