Yu Chen and colleagues describe a new constitutively activating mutation in the G-protein-coupled receptor CYSLTR2 in patients with uveal melanoma lacking mutations in the G-protein-encoding genes GNAQ and GNA11. They find that expression of the mutant leads to increased expression of melanocyte-lineage signature genes and promotes tumorigenesis in vivo.
