PacBio Vice President of Segment Marketing, Dr. Jennifer Stone, demonstrates how HiFi sequencing is changing the game in human genetics by sharing some of the exciting milestones and seminal publications our technology has produced this year.
There are many clinically important genes in “dark” regions of the human genome. These regions are characterized as dark due to a paucity of NGS coverage as a result of short-read sequencing or mapping difficulties. Low NGS sequencing yield can arise in these regions due to the presence of various repeat elements or biased base composition while inaccurate mapping can result from segmental duplications. Long-read sequencing coupled with an optimized, robust enrichment method has the potential to illuminate these dark regions.
Many genetic diseases are mapped to structurally complex loci. These regions contain highly similar paralogous alleles (>99% identity) that span kilobases within the human genome. Comprehensive screening for pathogenic variants is incomplete and labor intensive using short-reads or optical mapping. In contrast, long-range amplification and PacBio HiFi sequencing fully and directly resolve and phase a wide range of pathogenic variants without inference. To capitalize on the accuracy of HiFi data we designed a new amplicon analysis tool, pbAA. pbAA can rapidly deconvolve a mixture of haplotypes, enabling precise diplotyping, and disease allele classification.
The highly polymorphic CYP2D6 gene impacts the metabolism of 25% of the mostly prescribed drugs. Thus, accurate identification of variant CYP2D6 alleles in individuals is necessary for personalized medicine. PacBio HiFi sequencing produces long and accurate reads to identify variant regions. Here, we describe an end-to-end workflow for the characterization of full-length CYP2D6 by HiFi sequencing.

With the PacBio no-amplification (No-Amp) targeted sequencing method, you can now sequence through previously inaccessible regions of the genome to provide base-level resolution of disease-causing repeat expansions. By combining the CRISPR-Cas9 enrichment method with Single Molecule, Real-Time (SMRT) Sequencing on the Sequel Systems you are no longer limited by hard-to-amplify targets.
For many of the repeat expansion disorders, the disease gene has been discovered, however the underlying biological mechanisms have not yet been fully understood. This is mainly due to technological limitations that do not allow for the needed base-pair resolution of the long, repetitive genomic regions. We have developed a novel, amplification-free enrichment technique that uses the CRISPR/Cas9 system to target large repeat expansions. This method, in conjunction with PacBio’s long reads and uniform coverage, enables sequencing of these complex genomic regions. By using a PCR-free amplification method, we are able to access not only the repetitive elements and interruption…
