Additional file 3:

Parallel overlaps conserved between human and mouse. We manually reviewed the main literature on the genes involved in parallel OGCs conserved between human and mouse to look for possible functional links. We signed as 'Not Known' the cases where either the transcripts correspond to not yet annotated genes, or no functional link can be derived from the available literature.
