Figure 3. BRCA1 tumors associated with a basal tumor profile. A. Dendrogram showing all tumors from van't Veer et al, including 18 tumors from BRCA1 mutation carriers (black branches) and two tumors from BRCA2 mutation carriers (yellow branches). BRCA1 tumors are indicated with longer arrows; BRCA2 tumors are indicated with shorter arrows. B. Cluster of genes characteristic of basal tumors and highly expressed in tumors from BRCA1-carriers. (See also Figure 8, which is published as supporting information).
