An ultra-conserved element (UCE) was originally defined as a genome segment longer than 200 base pairs (bp) that is absolutely conserved, with no insertions or deletions and 100% identity, between orthologous regions of the human, rat, and mouse genomes. 481 ultra-conserved elements have been identified in the human genome. If ribosomal DNA (rDNA regions) are excluded, these range in size from 200 bp to 781 bp. UCRs are found on all chromosomes excep… WebUltraconserved elements: genomics, function and disease.
