Human RNA Editing (darned) Track Description


This track provides information on RNA nucleotides that are edited after transcription and their corresponding genomic coordinates. Only post-transcriptional editing that results in small changes to the identity of a nucleic acid are included in this track; it does not include other RNA processing such as splicing or methylation. The track contains information on A-to-I (adenosine-to-inosine) and C-to-U (cytidine-to-uridine) editing that occur due to deamination by ADAR and APOBEC enzymes, respectively. Most of the data in this track are on A-to-I editing, which is known to be highly abundant in humans.


Track items are colored depending on their occurrence within RNA transcripts:

  • Dark Green: 5' UTR
  • Blue: CDS
  • Red: Intron
  • Deep Pink: 3' UTR
  • Black: Other (exon/intron status is unclear or unknown)


The data were obtained from several research papers on RNA editing and were mapped to the reference genome. More information can be obtained from DARNED database.
