The top 9 expressed genes in the tumor cell subcluster were identified as follows: cell adhesion molecule 2 (Cadm2), myelin basic protein (Mbp), Rho-GTPase 2 (Rnd2), synaptotagmin (Syt4), cyclin-dependent kinase inhibitor 1B (Cdkn1b), ankyrin repeat domain 37 (Ankd37), long non-coding RNA (Cahm), endoplasmic reticulum reticular oxygen reductase 1 alpha (Ero1a), and transmembrane glucose transporter protein (Slc2a3). The gene discussed is CDKN1B; the disease is neoplasm.
