Table 3. Mechanisms of expression of overlapping genes.

Translational mechanisms (54 cases: 38 proven and 16 suspected)			Transcriptional mechanisms (17 cases: 16 proven and 1 suspected)
Alternative start codon^a	IRES^a	Ribosomal frameshifting^b	Subgenomic RNAs^a	Transcriptional slippage^b
29 proven and 16 suspected cases	2 proven cases	7 proven cases	12 proven and 1 suspected cases	4 proven cases

^aResults in a completely new coding sequence

^bResults in the fusion of a new coding sequence downstream of an existing coding sequence
