PacBio Supports SickKids to Investigate Use of HiFi Sequencing in Undiagnosed Genetic Conditions

SickKids Will Use HiFi Sequencing to Explore Potential Genetic Causes of a Range of Medical and Developmental Conditions

MENLO PARK, Calif., Feb. 28, 2022 (GLOBE NEWSWIRE) — PacBio, a leading provider of high-quality, highly accurate sequencing platforms, today announced it will be supporting The Hospital for Sick Children (SickKids) in Toronto, Canada in using HiFi whole genome sequencing (HiFi WGS) to potentially identify genetic variants that may be associated with medical and developmental conditions. Samples that will be examined using HiFi WGS were previously sequenced using short-read DNA sequencing technology, but still lack the identification of a disease-causing variant.

Even though more than 70 percent of rare disease, autism and intellectual disability have genetic causes, more than 50 percent lack an identified causative genetic alteration despite the use of microarrays, whole-exome or short-read whole-genome sequencing (srWGS).

SickKids will use HiFi WGS to analyze samples from research participants who are highly suspected to have a genetic condition but have not yet received a diagnosis despite previous genetic testing, including srWGS. The team will explore whether HiFi WGS can detect potential genetic causes for a range of conditions, such as autism spectrum disorder and congenital diseases.

“HiFi sequencing allows us to investigate the entire genome in a way that is not accessible with other technologies,” said Dr. Christian Marshall, Clinical Laboratory Director, Genome Diagnostics and Associate Director at The Centre for Applied Genomics (TCAG) at SickKids. “We hope HiFi sequencing will enable us to take an exploratory look at classes of variation and large sections of the genome that were not detected previously, potentially showing unidentified causative genomic variants in these samples.”

“PacBio’s technology has been used to help genetic disease researchers explain mysteries where other technologies could not,” said Edd Lee, Director of Human Genomics at PacBio. “We are excited to support the SickKids team to hopefully uncover the answers they have been seeking.”
