Fig. 2. Event types.

We assign a label ‘intergenic’ (purple) to any event that falls between transcripts; a label ‘coding’ (brown) is assigned to events that affect coding exons; a label ‘intercoding intronic’ (green) is assigned to events that affect an intron splitting two coding exons; a label ‘peripheral’ (blue) is assigned to events that affect coding transcripts but are neither coding nor ‘intercoding intronic’; a label ‘noncoding’ (yellow) is assigned to events that affect noncoding transcripts. The peripheral events affect the untranslated regions of the coding transcripts (UTRs) or the introns that split UTRs. We use RefSeq transcript models downloaded from the UCSC genome browser to find the genomic coordinates the exons³⁸.
