Spectrum of mutations in 213 patients in select MDS-associated genes. Each column represents an individual patient sample, and each colored cell represents a mutation of the gene or gene group listed to left of that row. The number of mutations for each row is indicated in the column to the right. Darker bars in the ASXL1 row indicate patients with a p.G642fs mutation. TK Pathway = NRAS, KRAS, CBL, CBLB, JAK2, PTPN11, BRAF, MPL, and KIT.
