The roots of pediatric cancer are hidden deep within a child’s DNA. The St. Jude—Washington University Pediatric Cancer Genome Project is the world’s most ambitious effort to discover the origins of childhood cancer and seek new cures.
By comparing the complete genomes from cancerous and normal cells for more than 800 patients, we have successfully pinpointed the genetic factors behind some of the toughest pediatric cancers. We are now using multiple approaches to analyze cancer genomes even more deeply. We are also developing a state-of-the-art clinical genomics program to better diagnose and treat children with cancer.
Raw sequence data for all published results, as well as data analysis and visualization tools, are freely available. Explore them today to advance your research and help us find cures.
Sharing a powerful resource with the global scientific community
To fuel new discoveries and treatments, we offer researchers access to the world’s largest collection of pediatric solid tumor samples and related drug sensitivity data at no charge. The resource, known as the Childhood Solid Tumor Network, is the result of a collaboration between St. Jude and the Howard Hughes Medical Institute and has already sparked research advances.
