Fig. 2. Distribution of somatic mutation types detected for each patient by Oncomine Focus DNA Assay in 26 GISTs. Individual patients are depicted on the x-axis, and identity of genes on the y-axis. Yellow box, amplification called; green box, frameshift mutation called; violet box, stop-loss mutation called; red box, nonsense mutation called; indigo box, missense mutation called; white box, no mutation called.

GIST = gastrointestinal stromal tumor; PDGFRA = platelet-derived growth factor receptor A; NIH = National Institutes of Health.
