CCDS release 22 for human is public in Gene


The Consensus Coding Sequence (CCDS) update that compares NCBI’s Homo sapiens annotation release 109 to Ensembl’s release 92 is now reflected in Gene. This update adds 894 new CCDS IDs, and adds 154 Genes into the human CCDS set. CCDS release 22 includes a total of 33,397 CCDS IDs that correspond to 19,033 GeneIDs.

The CCDS project is a collaborative effort to identify a core set of human and mouse protein coding regions that are consistently annotated and of high quality. The long-term goal is to support convergence towards a standard set of gene annotations.
