Eight U.S and Canadian healthcare organizations, researchers and vendors have launched a consortium that will work to expand access to high-quality clinical whole genome sequencing (cWGS) for the diagnosis of genetic diseases.
The Medical Genome Initiative will focus on the publication of common laboratory and clinical best practices for the application of cWGS. Founding members include Baylor Genetics; Broad Institute of MIT and Harvard; HudsonAlpha Institute for Biotechnology; Illumina Inc.; Mayo Clinic; Rady Children’s Institute for Genomic Medicine; The Hospital for Sick Children (SickKids Toronto); and Stanford Medicine.
Rare genetic diseases affect more than 350 million people globally and are a particularly significant source of morbidity and mortality among children, who commonly experience multiyear diagnostic evaluations with multiple misdiagnoses.
The consortium describes cWGS as a comprehensive method for analyzing the human genome in a clinical setting, noting that emerging evidence shows cWGS can detect most forms of clinically relevant variation for patients with a rare genetic disease.
Early deployment of cWGS has the potential to deliver precise molecular diagnosis to enable change in medical management, thereby reducing the number of unresolved, complex, costly and chronic genetic disease cases, especially for newborns and children. For cWGS to be implemented at scale, recommended best practices are useful to guide the clinical community, and the Medical Genome Initiative was created to address this need.
Initial topic areas of focus for the initiative include cWGS analytical validity, clinical utility measures, clinical data infrastructure and data sharing.
“With the launch of this consortium, we’re bringing together clinical laboratory and medical genomics experts who are pioneering the application of cWGS in routine clinical testing and clinical research for patients with genetic diseases,” says Christian Marshall, Ph.D., co-director of the Centre for Genetic Medicine at SickKids and Chairperson of the Medical Genome Initiative, in a prepared statement. “Emerging evidence on cWGS is positive, but clinical laboratories and healthcare systems looking to implement this technology for genetic-disease populations lack recommended best practices to inform test validation and deployment. By coming together, the Initiative can provide an informed perspective on how to best implement this promising new technology and measure its utility.”
