aType of conserved non-coding sequence (rCNE). bTotal number of rCNEs, including genic and nongenic. cNumber of genic rCNEs: overlapping EMBL proteins, ESTs, GenScan predictions, and Ensembl genes. dNumber of nongenic rCNEs: not overlapping EMBL proteins, ESTs, GenScan, and Ensembl genes. eTotal number of rCNEs, including pre-gene, intronic and post-gene. fNumber of pre-gene rCNEs: rCNEs localized before the translation start of the reference gene. gNumber of intronic rCNEs: rCNEs localized within the introns of the reference gene. hNumber of post-gene rCNEs: rCNEs localized after the translation end of the reference gene. EST, expressed sequence tag; rCNE, regionally conserved non-coding element.
