Article Synopsis
  • - Accurate gene annotations are essential for interpreting how genomes function, and the GENCODE consortium has spent twenty years creating reference annotations for human and mouse genomes, serving as a vital resource for researchers globally.
  • - Previous annotations of long non-coding RNAs (lncRNAs) were incomplete and poorly organized, hindering research, prompting GENCODE to launch a comprehensive effort that resulted in adding nearly 18,000 novel human genes and over 22,000 novel mouse genes, significantly increasing the catalog of transcripts.
  • - The new annotations not only show evolutionary patterns and link to genetic variants associated with traits but also improve understanding of previously unclear genomic functions, greatly advancing research into both human and mouse genetic diseases.
