From: Identification of mRNA isoform switching in breast cancer
Hierarchical clustering analysis of the top 6000 most variably expressed transcripts. a Overview of the clustering diagram of 728 breast tumors and 91 normal samples. Gene signatures of (b) basal, (c) luminal and (d) Her2 subtype were identified, with multiple isoforms from the same biomarker genes co-clustered
