Table 1.

Number of Alu-exonized events in different regions of the genes

Exonic regions	5′UTR	CDS	3′UTR
5′UTR	708^T (522^G)
CDS	28^T (32^G)	141^T (102^G)
3′UTR	88^T (110^G)	94^T (99^G)	3610^T (2328^G)

This table categorizes propensity of Alu-exonization events across different regions of the transcripts. Though there are exonization events observed in multiple region of the genes (G), the transcript isoform (T) involved in many cases is not the same. Hence, for cells denoting exonization in only one region, 5′UTR/CDS/3′UTR, number of transcripts are more than corresponding genes, whereas genes are higher in number when multiple regions are involved in exonization.
