Project description:ChIP-seq experiment of 14 human lymphoblastoid cell line samples from the 1000 Genomes sample set (http://www.1000genomes.org/). Dataset includes two parent-daughter trios (CEU and YRI populations) and additional eight unrelated individuals (CEU population). This accession contains raw and mapped ChIP-seq read data, other assays in this study are available under accession E-MTAB-1883 (RNA-seq, https://www.ebi.ac.uk/arrayexpress/experiments/E-MTAB-1883) and E-MTAB-1885 (GRO-seq, https://www.ebi.ac.uk/arrayexpress/experiments/E-MTAB-1885/).

Project description:It is becoming clear that copy number polymorphism in the human genome is a significant form of genetic variation. We have developed a new method that uses SNP genotype data from parent-offspring trios and applied it to HapMap to conduct high-resolution detection of deletion polymorphism. Of the delections uncovered, approximately 100 have been experimentally validated using comparative genome hybridization on these tiling-resolution oligonucleotide microarrays. We identified a total of 586 distinct regions that harbor deletion polymorphisms in one or more of the parent-offspring trios. This new method will permit future identification of deletion polymorphisms from high density SNP data derived from parent-offspring trios or other family relationships. Keywords: comparative genomic hybridisation
