Project description:The ideal genome sequence for medical interpretation is complete and diploid, capturing the full spectrum of genetic variation. Toward this end, there has been progress in discovery of single nucleotide polymorphism (SNP) and small (<10bp) insertion/deletions (indels), but annotation of larger structural variation (SV) including copy number variation (CNV) has been less comprehensive, even with available diploid sequence assemblies. We applied a multi-step sequence and microarray-based analysis to identify numerous previously unknown SVs within the first genome sequence reported from an individual. CGH experiments were performed with genomic DNA extracted from the HuRef and six HapMap lymphoblastoid cell lines, hybridized against the reference NA10851. A dye-swap experiment was performed for each experiment. The custom CGH microarray contains probes that target novel sequences that are not on the NCBI reference build 35. Instead, the probes target scaffold sequences that are unique to the Celera R27C assembly.

We applied a multi-step sequence and microarray-based analysis to identify numerous previously unknown SVs within the first genome sequence reported from an individual. Agilent array CGH experiment was performed according to the manufacturer's directions on DNA extracted from lymphoblastoid cell lines. HuRef genomic DNA was co-hybridized with female sample NA15510 from the Polymorphism Discovery Resource. No replicate nor dye swap was done. The Agilent 24 million features CGH array set was designed with 23.5 million 60-mer oligonucleotide probes tiled along the NCBI Build 36 assembly.

An Affymetrix SNP array experiment was performed according to the manufacturer's directions on DNA extracted from a lymphoblastoid cell line (HuRef). Copy number analysis of Affymetrix 6.0 SNP arrays was performed for the HuRef sample. The HuRef sample was run in a batch of 50 control samples, which were used as baseline for calling CNVs.

The HuRef genomic DNA (from lymphoblastoid cell line) was co-hybridized with the female sample NA15510 (from lymphoblastoid cell line) from the Polymorphism Discovery Resources. The NimbleGen platform consists of 20 NimbleGen HD2 chips, each containing 2.1M probes, and each chip is further subdivided into 3 equal-sized subarrays containing about 726K probes. The probes target the NCBI Build 36 genome, with the exception that no homology filter was applied, allowing coverage of segmentally duplicated regions.

Project description:Studying the functional consequences of structural variants (SVs) in mammalian genomes is challenging because: 1) SVs arise much less commonly than single nucleotide variants or small indels; and 2) methods to generate, map and characterize SVs in model systems are underdeveloped. To address these challenges, we developed Genome-Shuffle-seq, a method that enables the multiplex generation and mapping of thousands of SVs (deletions, inversions, translocations, extrachromosomal circles) throughout mammalian genomes. We also demonstrate the co-capture of SV identity with single-cell transcriptomes, facilitating the measurement of SVs’ impact on gene expression. We anticipate Genome-Shuffle-seq will be broadly useful for the systematic exploration of the functional consequences of SVs on gene expression, chromatin landscape, and 3D nuclear architecture, while also initiating a path towards a minimal mammalian genome.
