Counts by relative genic structure of members of paired dMCEs are shown. Exon-associated elements are type 1 and non-exon-associated elements are type2. Type 1 MCEs are further decomposed into three putative functional groups: type 1a (exonic), those completely contained within an exon; type 1b (partial exonic), those that span an intron-exons boundrary; and type 1c (UTR), those that include the 3'-UTR or 5'-UTR regions. Type 2 MCEs are divided into two subgroups: type 2a (intergenic), those located outside any annotated gene; and type 2b (intronic), those contained in the intron of an annotated gene. dMCE, duplicated most conserved element; UTR, untranslated region.
