GDB: The Genome Database (GDB), the official central repository for genomic mapping data resulting from the Human Genome Initiative. Established at Johns Hopkins University in Baltimore, Maryland, USA in 1990. In 1999, the Bioinformatics Supercomputing Centre (BiSC) at The Hospital for Sick Children in Toronto, Ontario, Canada, assumed the management of GDB. The Human Genome […]
