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 کاملCopy Number Variants and Segmental Duplications Show Different Formation Signatures
In addition to variation in terms of single nucleotide polymorphisms (SNPs), whole regions ranging from several kilobases up to a megabase in length differ in copy number among individuals. These differences are referred to as Copy Number Variants (CNVs) and extensive mapping of these is underway. Recent studies have highlighted their great prevalence in the human genome. Segmental Duplications...
متن کاملExpression divergence and copy number variation in the human genome.
DNA copy number variation (CNV) was recently discovered as a significant part of human genetic variation. This variation affects genes as well as intergenic regions. Herein, current insight into the effects of CNV on gene expression is summarized. The consequences of intergenic CNVs are poorly understood. For CNV affecting genes, a dosage compensation mechanism seems to be applied on a subset o...
متن کاملGenome Architecture and Its Roles in Human Copy Number Variation
Besides single-nucleotide variants in the human genome, large-scale genomic variants, such as copy number variations (CNVs), are being increasingly discovered as a genetic source of human diversity and the pathogenic factors of diseases. Recent experimental findings have shed light on the links between different genome architectures and CNV mutagenesis. In this review, we summarize various geno...
متن کاملCopy Number Variation in the Horse Genome
We constructed a 400K WG tiling oligoarray for the horse and applied it for the discovery of copy number variations (CNVs) in 38 normal horses of 16 diverse breeds, and the Przewalski horse. Probes on the array represented 18,763 autosomal and X-linked genes, and intergenic, sub-telomeric and chrY sequences. We identified 258 CNV regions (CNVRs) across all autosomes, chrX and chrUn, but not in ...
