We collected the transcriptome profiling data sets from the TCGA uveal melanoma (TCGA-UVM), breast cancer (TCGA-BRCA), and colon cancer (TCGA-COAD) projects to analyze the expression of BAP1. We found that patients with UM and breast cancer, but not colon cancer, who died had a lower level of BAP1 gene expression compared to surviving patients. This evidence concerns the gene BAP1 and breast cancer.
