Comparison of A→I editing density in introns intervening CDS and UTR exonic regions
| Exonic region | Number of A→I editing events within introns | Intron length (bp) | A→I editing density (editing sites/ Mb of intron) |
|---|---|---|---|
| 5′UTR | 5885 | 2.9 × 108 | 20.21 |
| CDS | 34 983 | 1.8 × 109 | 19.43 |
| 3′UTR | 508 | 7.58 × 106 | 66.99 |
The A-to-I editing density observed for 3'UTR region introns (highlighted in bold) is much higher than expected from its genomic coverage.
