We analyzed a published, multi-cancer RNA-Seq data [4], and came up with a set of 11 platelet genes (CD79B, CSDE1, IL-32, ITGA2B, LUC7L, NDUFAB1, RBM6, SKAP2, SS18L2, TRAF3IP3, and ZNF195) that enables accurate classification of cancer and healthy samples (refer Methods). The gene discussed is ITGA2B; the disease is cancer.
