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). This evidence concerns the gene INA and astrocytoma (excluding glioblastoma).
