From the 297 genes with strongest correlation (r>0.3) to NR2F1 in the human breast cancer data set, 64 (22%) were also found to be the strongest correlated (r>0.3) to Nr2f1 in the mouse MG data set, which is 1.3-fold enrichment in comparison to equally strongly correlated genes (r>0.3) to Nr2f1 in the entire mouse data set (17%). The gene discussed is NR2F1; the disease is breast carcinoma.
