Table 5.

Distance from the 3′-end of genes to the next gene either for all known protein-coding genes with a gene to their 3′-end, or only those with a predicted G-quadruplex immediately to the 3′-end of the gene

All known protein-coding genes Class Genes with G-PQS in 100 bases 3′ of TES Enrichment
No. (%) No. (%)
21643 (100) All with next gene 561 (100)
1589 (7.3) Overlapping (d ≤ 0) 50 (8.9) 1.21
20 054 (92.7) Non-overlapping (d > 0) 511 (91.1) 0.98
1633 (7.5) Near (0 < d ≤ 1000) 97 (17.3) 2.29
3376 (15.6) Medium (1000 < d ≤ 5000) 114 (20.3) 1.30
15 045 (69.5) Far (5000 < d) 300 (53.5) 0.77
3317 (15.3) Very far (100 000 < d) 51 (9.1) 0.59

The data is binned into categories where the next gene overlaps the previous one, is within 1 kb (‘near’, shown in bold), from 1 to 5 kb away (‘medium’) or >5 kb away (‘far’). The subset where the next gene is >100 kb away (‘very far’) is also shown. Genes where there was no subsequent gene (because they were near a chromosome end) are not shown. Enrichment is calculated as percentage with G-PQS/% of all genes for each class.
