We benchmarked iMOKA on a dataset of 1038 mRNA-Seq breast cancer samples from the Cancer Genome Atlas (TCGA) Pan-Gyn cohort [21] (patients per class: basal 190, Her2 82, LumA 559, LumB 207) and tested how well the outputs of each approach could accurately predict the four classes. This evidence concerns the gene ERBB2 and breast cancer.
