SAN FRANCISCO ­– As whole genome sequencing and other molecular diagnostic efforts take wing worldwide, new troves of biomedical data are being built daily. The power of that data, however, continues to be diminished by disconnection between data stores, hindering opportunities to accelerate progress in human health. One group, The Global Alliance for Genomics & Health (GA4GH), is working to reverse that trend, leading an effort to bring order to just a small corner of this world: BRCA1/2.
