+ ++The UCSC Genome Browser is getting ready to update hg19's UCSC Genes dataset for the first time +since 2013. In this update, the UCSC Genes track will now use GENCODE v45 gene models lifted to hg19 +and replace the old UCSC transcript IDs with the official GENCODE IDs. The anticipated released +date for this update is July 31, 2024.
+ ++As an example of what to expect, here are some GENCODE IDs that will replace the UCSC IDs in the +update:
+ ++oldId newId +uc003qfo.3 ENST00000341911.10_8 +uc003jsk.2 ENST00000462279.5_3 +uc003umk.1 ENST00000318238.9_6 +uc003gzi.3 ENST00000682860.1_2 +uc011dpu.2 ENST00000375023.3_6 +uc021raj.2 ENST00000258149.11_6 +uc002fxp.3 ENST00000341657.9_12 +uc010xhp.1 ENST00000429344.7_6 +uc003zze.3 ENST00000242285.11_9+ +
+For each transcript ID, the _# portion is part of the official hg19 backmap ID, so they are not +confused with the gene/transcript they are derived from in hg38. Between hg38 and hg19, the two IDs +are not always in the same sequence and may not be a one-to-one mapping. +
++With this update, we will also be freezing the previous 2013 knownGene release in a separate +archive track. Once new GENCODE versions are available, the previous track will then be added to the +archive for future reproducibility. More information about the knownGene archive will be available +once the update is released.
+We are pleased to announce new GENCODE Gene annotation tracks, which correspond to Ensembl 112, for three assemblies: hg19/GRCh37, hg38/GRCh38, and mm39/GRCm39. For human, the GENCODE V46 annotations were mapped to hg38/GRCh38 and then back-mapped to the hg19/GRCh37 assembly. For all three assemblies, the gene sets contain the following tracks:
