In this presentation, Dr. Marka van Blitterswijk shares the exciting results of her most recent targeted long-read sequencing study. Together with her colleagues, she performed No-Amp sequencing to examine an expanded GGGGCC-repeat in C9orf72, which causes fatal neurodegenerative diseases. Her team assessed the length of the C9orf72 expansion, as well as the presence of interruptions, thus revealing relevant clinico-pathological associations and demonstrating how powerful No-Amp sequencing is.
In this talk, Dr. Meredith Course presents her research on uncovering a 69-bp human-specific tandem repeat expansion in the final intron of WDR7. Larger repeat copy number is significantly associated with sporadic ALS cases, suggesting that it plays a role in disease susceptibility. Long-read sequencing reveals remarkable internal nucleotide variation, which was harnessed to determine the evolutionary origin of the expansion, its mechanism of replication, and its current state in modern-day humans. Each copy of the repeat has been determined to be able to form microRNAs and aggregate in cells and may sequester ALS-related RNA-binding proteins.
In this talk, Dr. Stephanie Tome describes using PacBio Single Molecule, Real-Time (SMRT) Sequencing to precisely measure large CTG repeat size and identify sequence interruptions of expanded allele to understand clinical and genetic variability in DM1 patients, sequencing several DM1 patients with CTG repeat expansion ranging from 130 to > 1000 CTG repeats on the Sequel I and II Systems from amplicons. She obtained more than 77% full DM1 reads per sample, with >70% of the reads from expanded alleles. The data includes long reads in the expected size range for all samples, including DM1 patients with more than 1000…
In this talk, Dr. Zachary McEachin describes how No-Amp targeted sequencing enables sequencing analysis of multiple (at least 15) Ataxia-related repeat expansion loci in one assay, presenting example sequencing results with selected samples from Ataxia patients and patients with unknown diagnostics. He demonstrates how PacBio HiFi sequencing with the No-Amp approach could provide repeat expansion and sequence interruption information at the target loci that is not available with PCR or southern-blot based diagnostics assays.
Through Pharmacogenomics (PGx), we can explore how a person’s genome affects their response to drugs to enable the development of safe and effective medications tailored to their genetic makeup. In this talk, you’ll learn how PacBio HiFi sequencing: is cost-effective and highly accurate; enables comprehensive interrogation of pharmacogenomics genes—detecting all types of variants even in challenging regions; allows for the sequencing of pharmacogenomics genes as single-gene assays or large panels; produces data that is highly concordant with other technologies—adding value through comprehensive variant detection, copy number assessment, and phasing.
Join PacBio’s Mike Weiand to hear how gene editing protocols can benefit from long-read sequencing at multiple stages to optimize and enhance vector integrity. This method allows researchers to reveal findings that other sequencing methods can not identify due to read-length limitations or amplification biases.
The Sequel IIe System produces highly accurate long reads (HiFi reads) quickly and cost-effectively thanks to increased computational capacity and on-instrument data processing. This results in a significant reduction of overall secondary analysis time and reduces the computational needs in terms of file transfer and data storage. This webinar provides an overview of PacBio data for beginner and advanced users of HiFi reads, exploring the content of PacBio BAM files, providing examples of how HiFi reads can be filtered, and going through recommendations for downstream analysis.
With highly accurate long reads (HiFi reads) of >99% accuracy, the Sequel IIe System is the tool of choice for producing reference quality assemblies, calling variants with the highest precision, reading full-length transcripts, characterizing isoform diversity, and many more applications. To maximize the quality of your results, DNA and sample preparation are critical steps in your sequencing workflow. In this webinar we cover the following points: preparing DNA for PacBio HiFi sequencing, selecting the right HiFi library preparation protocol for your project, and interpreting sequencing metrics and troubleshooting.

Over the past few years, many tools have been developed to enable comprehensive variant detection from PacBio HiFi reads. This talk describes a flexible, modular workflow for variant detection and prioritization from HiFi whole-genome sequencing data, including open-source tools for quality control, alignment, small variant detection, and phasing, structural variant detection, genotyping of tandem repeats, and de novo assembly. This pipeline is available on GitHub as a Snakemake workflow and has been adapted into a Cromwell WDL workflow by Microsoft Genomics.
Alexander Hoischen’s research group ‘Genomic Technologies and Immuno-Genomics’ has expertise in the identification of rare disease genes using the latest genomics tools, with a recent particular focus on immune-related disease genes. His group has been the first to identify a disease causing dominant de novo mutation for a Mendelian disorder by exome sequencing, followed by the identification of several disease genes for rare diseases. Following a six-month research stint in 2013 in the laboratories of collaborators, Prof. Eichler and Prof. Shendure (UW, Seattle; USA), Dr. Hoischen established the latest technology for accurate and large-scale targeted re-sequencing (smMIPs) in Nijmegen. Recently,…
In this talk, Christine Lambert describes a simple and scalable workflow for generating high-quality HiFi reads appropriate for comprehensive variant detection (SNVs, Indels, SVs) and de novo assembly. Using this workflow, multiple samples can be processed manually (up to 16) with a multichannel pipet and strip tubes. Up to 96 samples can be processed on an automated liquid handler such as the Sciclone Liquid Handler Workstation. She also describes solutions for high-throughput SMRTbell library construction for generating HiFi reads on the Sequel IIe System.
In this talk, Dr. Ekholm describes how long-read sequencing is being incorporated for rare Mendelian disease research, why high accuracy matters in long-read sequencing, what can be detected with HiFi reads that is missed with standard sequencing methods, and finally, how long-read sequencing can help increase the solve rates for rare and Mendelian diseases.
