MENLO PARK, Calif., April 11, 2018 (GLOBE NEWSWIRE) — Pacific Biosciences of California, Inc. (Nasdaq:PACB), the leader in long-read, high-resolution sequencing, today announced that the HudsonAlpha Institute for Biotechnology is using the organization’s newest Sequel® Sequencing System to support the goal of dramatically increasing the diagnostic success rate in challenging pediatric clinical cases.
Led by faculty investigator Greg Cooper, Ph.D., the institution’s NIH-funded Clinical Sequencing Exploratory Research (CSER) project is applying whole genome sequencing to better understand the genetic basis of intellectual and developmental disabilities in children and provide diagnostic information to affected families. More than 500 children and their parents have been enrolled in the study.The group’s efforts to diagnose these children using short-read sequencing technology have achieved a success rate of about 30 percent, but it is widely known that these platforms are unable to detect certain types of genetic variation that contribute to disease. Structural variants such as repeat expansions and copy number variations are larger and more complex than short-read sequencers can typically resolve, and likely underlie some of the cases that have gone undiagnosed. Diseases already known to be caused by these larger structural variants include ALS, autism, Fragile X syndrome, and Huntington’s disease, among others. HudsonAlpha is now applying PacBio® long-read sequencing technology for whole genome sequencing of affected children along with their parents. This approach could produce answers for many cases that have proven intractable with other technologies.“By applying whole genome PacBio Sequencing in this study we hope to more sensitively identify all sizes of genetic variants, thereby increasing our solve rate for previously undiagnosed children,” said Dr. Cooper. “In many cases, an accurate clinical diagnosis can improve our ability to manage the child’s condition. We also anticipate that we will make novel discoveries through this work that may benefit many families beyond those directly tested here.”Scientists at HudsonAlpha have been using PacBio Single Molecule, Real-Time (SMRT®) Sequencing technology in their agricultural biology work. Based on success applying long-read SMRT Sequencing to challenging plant genomes, the organization has added a second Sequel System for clinical research use in addition to its existing PacBio instrumentation used for AgBio research — a Sequel System as well as a PacBio RS II System.“PacBio Sequencing has made it possible for us to generate high-quality reference genomes for most plants, and we now want to apply the benefits of this technology in the human disease space,” said Jeremy Schmutz, another HudsonAlpha faculty investigator. “With further scale increases and cost decreases in the future, true individual de novo genome sequencing may become the tool of choice for addressing difficult medical cases.”Kevin Corcoran, Senior Vice President for Market Development at Pacific Biosciences commented: “We believe projects like HudsonAlpha’s CSER program to help solve undiagnosed genetic disease in children are among the most important and rewarding uses for our technology. We are delighted to see that one of our most successful customers working in the plant sciences has decided to apply our long-read technology to their research in patient populations. We look forward to seeing how PacBio sequencing can both improve their clinical sequencing success rate as well as support new discoveries.”A number of other studies have been announced in the past year that are using, or plan to use, highly accurate PacBio whole-genome sequencing to with a goal of increasing the solve rate for genetic disease. These include Stanford University School of Medicine; the European Solve-RD Consortium, which is performing a 500-individual rare disease study; and Novogene, which has announced plans to sequence 1,000 Chinese genomes.About Pacific Biosciences
