Project name: An_evaluation_of_different_strategies_for_large_scale_pooled_sequencing_study_design_

Description: Second generation sequencing technology has enabled the design of large-scale sequencing experiments in targeted disease-related regions in thousands of cases and controls. Cost implications dictate a pooled DNA sequencing design, evaluation of allele frequency differences based on the resequenced samples and large-scale targeted follow-up in further samples. To evaluate the feasibility of this approach and to assess different study design strategies, we have carried out a pilot study which tests the feasibility of PCR-based and pull-down DNA pooling for (a) SNP discovery and (b) allele frequency comparison purposes. All samples are from the HapMap. The sample composition of different pools is listed below:Pool 1: 1 HapMap Individual (NA12249)Pool 2: 2 HapMap Individuals (NA12249, NA12156)Pool 3: 10 HapMap Individuals (NA12249, NA12156, NA12004, NA11831, NA12716, NA11832, NA11993, NA12057, NA11995, NA12006)Pool 4: 20 HapMap Individuals (NA12249, NA12156, NA12004, NA11831, NA12716, NA11832, NA11993, NA12057, NA11995, NA12006, NA12144, NA12802, NA12146, NA12005, NA12003, NA07000, NA12043, NA12044, NA11992, NA11881)Some pools were carried out in duplicate to assess reproducibility. We focused on 10 (PD), 7(PCR) chromosomal regions, ~2(PD), ~1.6 (PCR) Mb in total.This data is part of a pre-publication release.
