By the analysis of the astrocytoma network, we identified a potential interesting subnetwork constituted by 3 exclusive genes, FAM123C (APC Membrane Recruitment Protein 3)—also selected in the regularized survival model)—ACTL6B (Actin Like 6B), and INA (Internexin Neuronal Intermediate Filament Protein Alpha). The gene discussed is AMER3; the disease is astrocytoma (excluding glioblastoma).
