Children’s Mercy Kansas City Expands Investment in Pacific Biosciences Sequel IIe Systems to Scale Up Whole Genome Research Initiatives Focused on Rare Disease Diagnosis
Wednesday, February 24, 2021
PacBio’s highly accurate HiFi sequencing will help clinical researchers identify disease-causing genetic variants and increase our understanding of rare diseases
KANSAS CITY, Mo. and MENLO PARK, Calif., Feb. 24, 2021 (GLOBE NEWSWIRE) — Pacific Biosciences of California, Inc. (Nasdaq: PACB), a leading provider of high-quality, long-read sequencing platforms, today announced that Children’s Mercy Kansas City, one of the nation’s top pediatric medical centers, has increased its investment in highly accurate HiFi sequencing with four new Sequel IIe Systems to add to its two existing Sequel IIe Systems. These additional systems will significantly increase Children’s Mercy’s large-scale whole genome sequencing capacity and help accelerate its initiatives focused on identifying potential disease-causing genetic variants and increasing solve rates for families and children living with undiagnosed rare diseases.
In October 2020, Children’s Mercy and PacBio announced a research collaboration focused on long-read whole genome sequencing of rare disease cases for which previous short-read whole genome and exome sequencing studies yielded no answers. The study, which is currently underway, has already resulted in the detection of multiple new diagnoses, including a novel expansion disorder, precise definition of breakpoints and orientation of structural and copy number variants, and the identification of novel inversions. Based on the success of that collaborative effort, Children’s Mercy is scaling their sequencing capacity with the goal of completing PacBio HiFi whole genome sequencing for approximately 1,000 exome-negative cases over the next 12 months.
“Thousands of children do not have a clear explanation for what are likely genetic-driven diseases. We are committed to addressing this challenge by refining genomic sequencing to achieve a higher-resolution view of all DNA variation using technologies such as the Sequel IIe System,” said Tomi Pastinen, MD, PhD, Director of the Center for Pediatric Genomic Medicine at Children’s Mercy. “The accuracy and completeness of genomes provided by PacBio’s HiFi reads from the Sequel IIe System have already helped us explain seemingly intractable cases. We expect HiFi whole genome sequencing to help us shorten the diagnostic journey for families not helped by current clinical genome or exome sequencing. Studying the genetics of thousands of children will help us make rapid progress against unknown genetic diseases and lead the way for more children and families in need.”
The PacBio Sequel IIe System generates HiFi sequencing reads, which provide the accuracy and completeness required for investigating DNA variation in rare genetic diseases. Short-read whole genome sequencing can lead to sequence gaps and incomplete coverage of disease-causing gene regions. HiFi whole genome sequencing produces reads approximately 100 times longer than short-read whole genome sequencing, providing high-quality mapping across a genome for comprehensive variant detection. As part of their collaboration, scientists at Children’s Mercy and PacBio will take advantage of the ability of HiFi sequencing data to reproduce all variants previously detected by short-read whole exome and whole genome methods and to identify novel variants that could explain disease phenotypes.
“At least half of known rare disease cases have not been explained with existing short-read sequencing or other techniques. As a result, we are seeing tremendous interest in HiFi sequencing as an important new tool for detecting large or challenging variants missed by short reads, with early successes showing the enormous promise of this exciting technology,” said Christian Henry, President and Chief Executive Officer of Pacific Biosciences. “We are proud to support Children’s Mercy, which for more than 120 years has been committed to the mission of creating a world of well-being for children. It is important to remember that each of these explained cases represents a family that is now closer to the end of their diagnostic odyssey. We look forward to continuing our collaboration and working every day to bring advanced genomic technologies to help people live longer, healthier lives.”
The six PacBio Sequel IIe Systems will be installed in the new Children’s Mercy Research Institute (CMRI) building, which was opened on February 18, 2021. The Institute’s new nine-story, 375,000-square-foot building features state-of-the-art laboratories that will support a collaborative approach to research, fostering a partnership among healthcare professionals, researchers, patients, and families.

Findings from the PacBio and Children’s Mercy research collaboration will be delivered in a platform presentation at the ACMG Annual Clinical Genetics Meeting, April 15, 2021. The presentation, titled, “Clinical Application of Long-Read Sequencing in Unsolved Rare Disease,” will be given by Emily Farrow, PhD, CGC, Director, Laboratory Operations, Genomic Medicine Center, Children’s Mercy Kansas City.
