Additional file 4 of Molecular profiling of the Basal-like intrinsic molecular subtype in primary ER-positive HER2-negative breast cancer

Additional file 4. ERpHER2n Basal-like copy number data and alteration frequencies. This Excel file provides gene-level copy number gain and loss frequencies per subgroup. It also provides the results of statistical tests comparing these frequencies in ERpHER2n Basal-like cases to other subgroups and the genes found to be significantly differing in these comparisons.
