DupMasker: A tool for annotating primate segmental duplications Export

@article{jiang:dupmasker, abstract = {Segmental duplications (SD) play an important role in genome rearrangement, evolution and the copy-number variation (CNV) of primate genomes. Such sequences are difficult to detect, a priori, because they share no defining sequence features that distinguish them from unique portions of the genome. Current sequence annotation of segmental duplications requires computationally intensive, genome-wide self-comparisons that can not be easily implemented on new datasets. Based on the successful implementation of RepeatMasker, we developed a new genome annotation tool, DupMasker. The program uses a library of non-redundant consensus sequences of human segmental duplications, wherein a majority of the ancestral origins have been determined based on comparisons to mammalian outgroup genomes. Using DupMasker, new human and non-human primate (NHP) sequences may be readily queried to provide details on the origin and degree of sequence identity of each duplicon. This program can be applied to delineate the order and orientation of duplicons within complex duplication blocks and used to characterize structural variation differences between sequenced human haplotypes.
