Genome & Biomarker Sciences

Our journey for cutting-edge medicines for patients

The Genome and Biomarker Sciences (GBx) unit advances targets rooted in human genetics and genomics. We invest in innovative genomic and biomarker technologies for maximal pipeline impact. We leverage disease-relevant tissue samples to identify and apply genomic and protein biomarkers to inform clinical decision-making and exploratory research. Our goal is to translate the best human genetic targets into actionable biology.
