Heat map with samples categorized according to BAF250a IHC scores and
mutation status. No obvious clustering patterns due to either BAF250a by IHC or PIK3CA mutation status are present. Note: capital letters for each sample histotype label (eg. CCC) indicates expression of BAF250a on IHC, small letters (e.g. ccc) indicates loss of BAF250a expression. For PIK3CA mutations, a + sign after the sample label (e.g. CCC+) indicates the presence of a PIK3CA mutation (either helical, kinase, or other) whereas a – sign indicates no mutation.
