Heatmap of genomic mutation data for multiple pediatric leukemias and solid tumors. Here samples (columns) are grouped by cancer subtype; genes (rows) harboring mutations are grouped by functional class. The color for each type of genetic alteration is defined. Mousing over each instance of a mutation provides further information (sample, mutation type, amino acid change, and gene name). Clicking on each gene symbol opens a GenomePaint view of mutations found within the gene across samples in this cohort Numbers in parentheses next to each gene symbol indicate the number of samples altered.
