a-b. Landscape of putative driver genes and sCNAs in M-CLL (a, n=512) and U-CLL (b, n=459) with associated frequencies (rows, barplots). Header tracks annotate cohort, IGHV status (purple, M-CLL; orange, U-CLL), disease type (blue, CLL; yellow, MBL), epitype (blue, n-CLL; yellow, i-CLL; red, m-CLL), datatype (white, WES; yellow, WGS; blue, both); prior treatment, U1 and IGLV3–21R110 mutations are annotated in black; magenta label - novel alterations; asterisks - discovery by CLUMPS.
