We found out that for the top 20 processes of the brown module, 97 genes (Figure 6c) have a significant role (p-value < 0.05, FDR < 0.01) in normal nervous system pathways [43,44,45] whose impairment has been related to neuroblastoma [57,58], such as neuronal system, chemical synapses, neurotransmitter receptors, potassium channels, postsynaptic signaling, and others (Figure 6a). The gene discussed is KCNA3; the disease is neuroblastoma.
