Adam Ameur talks about a range of applications for which SMRT Sequencing had been useful in the SciLifeLab. Examples include analyzing a DNA translocation in chronic myeloid leukemia samples; studying the HPV genome; and sequencing the FADS region to understand fatty acid production.
Andrew Carroll, Director of Science at DNAnexus, presents how to greatly improve the accuracy of SV-calling by using long-read PacBio sequencing and fast and easy-to-run cloud-optimized apps like PBHoney, Parliament, and Sniffles.
Fritz Sedlazeck, a postdoc at Johns Hopkins University, describes his structural variant detection tool Sniffles in this poster from AGBT 2016. Included: examples of structural variants that could not be detected with other algorithms.
Most of the basepairs that differ between two human genomes are in intermediate-sized structural variants (50 bp to 5 kb), which are too small to detect with array CGH but too large to reliably discover with short-read NGS. PacBio Single Molecule, Real-Time (SMRT) Sequencing fills this technology gap. SMRT Sequencing detects tens of thousands of structural variants in a human genome, approximately five times the sensitivity of short-read NGS. To discover variants using SMRT Sequencing, we have developed pbsv, which is available in version 5 of the PacBio SMRT Link software suite. The pbsv algorithm applies a sequence of stages:…
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 ASHG 2017 presentation, Jonas Korlach, the CSO of PacBio shared updates on three applications featuring SMRT Sequencing on the Sequel System, highlighting structural variant detection, targeted sequencing and the Iso-Seq method of RNA sequencing. He provided details on structural variant calling using pbsv to call insertions and deletions and compared PacBio variant calling with other technologies. Korlach described how targeted sequencing can be used to interrogate repeat expansions, detect and phase minor variants and can access medically relevant but previously inaccessible gene targets. He presented research featuring the Iso-Seq method that identified isoforms, corrected previous isoform annotations and…
In this ASHG 2017 presentation, Han Brunner of Radboud University Medical Center presented research using SMRT Sequencing to detect structural variants to uncover the genetic causes of intellectual disability. He shared that long-read sequencing enabled detection of 25,000 structural variants per genome. Brunner presented data from patient trios to identify de novo structural variant candidates and ongoing validation work to determine the causative mutations of intellectual disability.
In this video, Aaron Wenger, a research scientist at PacBio, describes the use of long-read SMRT Sequencing to detect structural variants in the human genome. He shares that structural variations – such as insertions and deletions – impact human traits, cause disease, and differentiate humans from other species. Wenger highlights the use of SMRT Sequencing and structural variant calling software tools in a collaboration with Stanford University which identified a disease-causing genetic mutation.
In this webinar, Emily Hatas of PacBio shares information about the applications and benefits of SMRT Sequencing in plant and animal biology, agriculture, and industrial research fields. This session contains an overview of several applications: whole-genome sequencing for de novo assembly; transcript isoform sequencing (Iso-Seq) method for genome annotation; targeted sequencing solutions; and metagenomics and microbial interactions. High-level workflows and best practices are discussed for key applications.
In this presentation Fritz Sedlazeck describes his latest work to obtain comprehensive genomes leveraging long-read sequencing and linked reads.
Explore human genetic variation and learn how SMRT Sequencing uncovers the full spectrum of structural variation to advance understanding of genetic disease and broaden our knowledge of human diversity.
Structural variants (SVs, differences >50 base pairs) account for most of the base pairs that differ between two human genomes, and are known to cause over 1,000 genetic disorders including ALS, schizophrenia, and hereditary cancer. Yet, SVs remain overlooked in human genetic research studies due to the limited power of short-read sequencing methods (exome and whole genome sequencing) to resolve large variants, which often involve repetitive DNA. Recent advances in long-read sequencing have made it possible to detect the over 20,000 SVs that are now known to exist in a human genome. Corresponding advances in long-read SV calling algorithms have…
In this PacBio User Group Meeting presentation, Jonas Korlach and Roberto Lleras share the latest updates to the structural variation application and analysis tools.
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.
In this PacBio User Group Meeting presentation, PacBio scientist Kristin Mars speaks about recent updates, such as the single-day library prep that’s now possible with the Iso-Seq Express workflow. She also notes that one SMRT Cell 8M is sufficient for most Iso-Seq experiments for whole transcriptome sequencing at an affordable price.
