Some of the signature genes related to the AML pathway by the GlobalAncova-based approach and by the gene association networks are reported to play a role in other types of tumors, e.g. BCAT1 (Entrez GeneID 586) (Rodríguez et al. 2003) and SCHIP1 (Entrez GeneID 29970) (Scoles, 2008). The gene discussed is SCHIP1; the disease is acute myeloid leukemia.
