The new five subsets classification of circRNAs. Legend: CircRNAs can be divided into five groups according to their location relationship with coding RNA. “exonic” and “intronic” represent circRNA composed by exons and intros respectively, “antisense” represents circRNA whose gene locus overlap with the linear RNA, but transcribed from the opposite strand; “sense overlapping” represents circRNA transcribed from same gene locus as the linear transcript, but not classified into “exonic” and “intronic”; “intergenic” represents circRNA located outside known gene locus
