To bring personalized medicine to all patients, cancer researchers need more reliable and comprehensive views of somatic variants of all sizes that drive cancer biology.
With the Sequel II System powered by Single Molecule, Real-Time (SMRT) Sequencing technology and SMRT Link v8.0, you can affordably and effectively detect structural variants (SVs), copy number variants, and large indels ranging in size from tens to thousands of base pairs. PacBio long-read whole genome sequencing comprehensively resolves variants in an individual with high precision and recall. For population genetics and pedigree studies, joint calling powers rapid discovery of common variants within a sample cohort.
Structural variation accounts for much of the variation among human genomes. Structural variants of all types are known to cause Mendelian disease and contribute to complex disease. Learn how long-read sequencing is enabling detection of the full spectrum of structural variants to advance the study of human disease, evolution and genetic diversity.
Ali Bashir from the Icahn Institute for Genomics and Multiscale Biology at Mount Sinai describes a tool to detect tandem repeats (PACMonSTR), which he believes are dramatically underrepresented in the human genome reference but that can be discovered with PacBio sequencing. In a collaboration with Cold Spring Harbor Laboratory and Cornell, Bashir and his team generated shotgun, whole-genome sequence data from human genomic DNA using PacBio sequencing. Their goal was to find structural variation features that are not present in the existing reference. He shows numerous examples wherein the long PacBio reads were able to resolve inversions in the sample,…
Michael Schatz of Cold Spring Harbor Laboratory and Johns Hopkins University discusses the challenges in detecting structural variations (SVs) in high throughput sequencing data, especially more complex SVs such as a duplication nested within an inversion. To overcome these challenges, Dr. Schatz and his team have been applying long-read sequencing to analyze SVs in a range of samples from small microbial genomes, through mid-sized plant and animal genomes, to large mammalian genomes. The increased read lengths, which currently average over 10kbp and some approach 100kbp, make it possible to span more complex SVs and accurately assess SVs in repetitive regions,…
At AGBT 2017, Mike Schatz from Johns Hopkins University and Cold Spring Harbor Laboratory presented data from sequencing, assembling, and analyzing personalized, phased diploid genomes with either Illumina, 10x Genomics, and PacBio SMRT Sequencing. Compared to the short-read-based methods, PacBio data assembled in large, complete contigs and contained the broadest range of structural variants with the best resolution. Plus: unexpected translocation findings with SMRT Sequencing, validated in follow-up studies.
In this Webinar, we will give an introduction to Pacific Biosciences’ single molecule, real-time (SMRT) sequencing. After showing how the system works, we will discuss the main features of the technology with an emphasis on the difference between systematic error and random error and how SMRT sequencing produces better consensus accuracy than other systems. Following this, we will discuss several ground-breaking discoveries in medical science that were made possible by the longs reads and high accuracy of SMRT Sequencing.
In this ASHG 2017 presentation, Charles Lee of The Jackson Laboratory for Genomic Medicine presented work from the Human Genome Structural Variation Consortium. He shared data from efforts to utilize multiple platforms for the comprehensive discovery of structural variations—including insertions, deletions, inversions and mobile element insertions—in individual genomes. By combining various technologies, this research identified 7 times more structural variation per person than was previously known to exist.
In this ASHG workshop presentation , Jonas Korlach, CSO of PacBio, walked attendees through recent product updates and the coming technology roadmap. The Sequel System 6.0 release offered major improvements to accuracy, throughput, structural variant calling, and large-insert libraries, he said, showing examples of 35 kb libraries. Looking ahead, Korlach said that the V2 express library preparation product should be available early in 2019, with the new 8M SMRT Cell being introduced sometime later.
This tutorial provides an overview of the Structural Variant Calling application in SMRT Link and a live demo of how to launch an analysis in SMRT Link and interpret the results. This application identifies large (default: = 20 bp) insertions, deletions, inversions and translocations in a sample relative to a reference from.This tutorial covers features of SMRT Link v6.0.0.
In this webinar, Lori Aro and Cheryl Heiner of PacBio describe how high-throughput amplicon sequencing using Single Molecule, Real-Time (SMRT) Sequencing and the Sequel System allows for the easy and cost-effective generation of high-fidelity, long reads from amplicons ranging in size from several hundred base pairs to 20 kb. Topics covered include the latest advances in SMRT Sequencing performance for detection of all variant types even in difficult to sequence regions of the genome, multiplexing options to increase throughput and improve efficiency, and examples of amplicon sequencing of clinically relevant targets.
