Fold change variation versus average intensities of putative TAAs in van't Veer data set. Log10 fold change variation with respect to a reference pool (the reference pool is made of the same amount of all sporadic patients ) is plotted in function of log10 average intensities . The 9 putative TAAs are grouped with respect to Her2 expression as medium expressed and low expressed. Genes belonging to the medium expressed group have a median average expression level between 1/10 to 1/100 of median Her2 expression. Genes belonging to the low expressed group have a median average expression level lower than 1/100 of median Her2 expression.
