Gene-expression signature unique to WM. Seventy-three genes, 48 up-regulated and 25 down-regulated, constitute a gene-expression signature unique to WM. Here the samples are ordered according to diagnosis and genes according to fold difference in expression between WM and CLL and MM. Some interesting genes are highlighted. For a more complete list, see Table S1. The scale of the gene-expression data is similar to that in Figure 1A.
