1. A, unsupervised clustering of all BRCA1 (red), BRCA2 (blue), and sporadic (green) breast tumors of our collection using the regions reported as discriminative in the aCGH classifier by Jönsson et al.
A, unsupervised clustering of all BRCA1 (red), BRCA2 (blue), and sporadic (green) breast tumors of our collection using the regions reported as discriminative in the aCGH classifier by Jönsson et al. (20). Regions are listed according to chromosome number and are considered as gains (red), no change (black), or losses (green). Black circle, ER+; red circle, ER−; white circle, nonevaluated cases. B, unsupervised clustering of BRCA1 (red), BRCA2 (blue), and sporadic (green) breast tumors with BRCA1 ER+ and BRCA2 ER− tumors removed.
