LncRNAs classification attending to genomic position.
| LncRNA Category | Definition | Example | |
|---|---|---|---|
| Genic | Genic intronic lncRNA | LncRNA overlapping a protein-coding intron at one or more nucleotides |
|
| Genic exonic lncRNA | LncRNA overlapping a protein-coding exon at one or more nucleotides |
|
|
| Nested lncRNA | LncRNA genes contained entirely within protein-coding transcripts |
|
|
| Overlapping lncRNA | LncRNA genes sharing one or more nucleotides with coding genes |
|
|
| Intergenic | LincRNA | Long-intergenic non-coding RNA. No overlapping, no close to a protein-coding transcript |
|
| Same strand | LincRNA within 50 kb of and transcribed from the same strand and in the same direction as the nearest protein-coding transcript |
|
|
| Convergent | LincRNA within 50 kb of and transcribed head-to-head with the nearest protein-coding transcript |
|
|
| Divergent | LincRNA within 50 kb of and transcribed tail-to-tail with the nearest protein-coding transcript |
