Stratified medicine promises to tailor treatment for individual patients, however it remains a major challenge to leverage genetic risk data to aid patient stratification. Here the authors introduce an approach to stratify individuals based on the aggregated impact of their genetic risk factor profiles on tissue-specific gene expression levels, and highlight its ability to identify biologically meaningful and clinically actionable patient subgroups, supporting the notion of different patient ‘biotypes’ characterized by partially distinct disease mechanisms.

Pierre Guermonprez and colleagues have worked out how a subset of dendritic cells expands in individuals with severe malaria. Plasmodium infection causes an accumulation of xanthine in infected red blood cells. The researchers found that type I interferon triggers an increase in the enzyme that metabolizes xanthine to uric acid. Uric acid then acts on mast cells to release Flt3 ligand, an important regulator of dendritic cells, which in turn stimulate T cells to respond to the infection.
