First Automated Diagnostic DNA Sequence Lab Opens Doors
By Stephanie Yanchinski
The Eye Research Institute of Canada (ERIC) has opened its doors in Toronto as the world’s first clinical diagnostic laboratory for automated DNA analysis. At the opening, ERIC, in partnership with the Swedish firm Pharmacia Biotech and the Canadian Genetic Diseases Network, unveiled a system for routinely diagnosing retinoblastoma (RB), a relatively rare inherited tumor that can result in total blindness or death in young children.
The Diagnostic Laboratory of the Twenty-First Century (DL21C) will use the Uppsala-based company’s Sequence-Based Diagnosis (SBD™) for analyzing human DNA base by base. SBD integrates a package of technologies for the entire process, from extracting the DNA from blood or biopsy to presenting results in a computer printout.
However, according to John K. Stevens, Ph.D., ERIC’s director, “This is just the beginning. It provides a foundation for diagnosing many other diseases in a cost-effective way.” He believes that eventually SBD may have the capability of detecting up to 4,000 genetically linked conditions long before symptoms appear. “This makes early intervention—and cures—much more likely,” he says, with substantial cost savings to the healthcare system.
The Eye Research Institute of Canada was conceived in 1984 by a group of ophthalmologists to pursue innovative research programs to help cure eye disease and prevent blindness. The Institute’s facility was created with a C$4.5 million grant from the Ontario government. Corporate sponsors such as the Royal Bank of Canada and the Canadian Imperial Bank of Commerce and a number of foundations contributed $3.5 million, paving the way for the establishment of the DL21C.
The project to develop automated sequencing—the key to DL21C—began three years ago when Dr. Stevens and Brenda Gallie, M.D., director of molecular genetics at the Institute and senior scientist of the department of ophthalmology, immunology and cancer at the Hospital for Sick Children in Toronto, became convinced that automation was the best route for diagnosing inherited diseases like RB.
They turned to Pharmacia Biotech for help and the company worked closely with the Institute’s team of ten clinical researchers. Pharmacia supplied sequencers, reagents and the support of their systems experts to help make SBD a reality.
