Golub-score analysis identified a relatively poor discriminatory signal of 200 genes for the fibrosarcomas, which regardless of high FDR contained several of the upregulated genes previously associated with fibrosarcoma, e.g. BMI1, H1F0, LEF1, RBM4, ITM2A, IGFBP2 and PTGS2 [10]. The gene discussed is ITM2A; the disease is fibrosarcoma.
