Recent segmental duplications in the human genome.
Primate-specific segmental duplications are considered important in human disease and evolution. The inability to distinguish between allelic and duplication sequence overlap has hampered their characterization as well as assembly and annotation of our genome. We developed a method whereby each public sequence is analyzed at the clone level for overrepresentation within a whole-genome shotgun s...
متن کاملAnalysis of segmental duplications and genome assembly in the mouse.
Limited comparative studies suggest that the human genome is particularly enriched for recent segmental duplications. The extent of segmental duplications in other mammalian genomes is unknown and confounded by methodological differences in genome assembly. Here, we present a detailed analysis of recent duplication content within the mouse genome using a whole-genome assembly comparison method ...
متن کاملPhylogenomic analysis reveals ancient segmental duplications in the human genome.
Evolution of organismal complexity and origin of novelties during vertebrate history has been widely explored in context of both regulation of gene expression and gene duplication events. Ohno (1970) for the first time put forward the idea of two rounds whole genome duplication events as the most plausible explanation for evolutionarizing the vertebrate lineage (2R hypothesis). To test the vali...
متن کاملStability of large segmental duplications in the yeast genome.
The high level of gene redundancy that characterizes eukaryotic genomes results in part from segmental duplications. Spontaneous duplications of large chromosomal segments have been experimentally demonstrated in yeast. However, the dynamics of inheritance of such structures and their eventual fixation in populations remain largely unsolved. We analyzed the stability of a vast panel of large se...
متن کاملDAGchainer: a tool for mining segmental genome duplications and synteny
SUMMARY Given the positions of protein-coding genes along genomic sequence and probability values for protein alignments between genes, DAGchainer identifies chains of gene pairs sharing conserved order between genomic regions, by identifying paths through a directed acyclic graph (DAG). These chains of collinear gene pairs can represent segmentally duplicated regions and genes within a single ...
