Several categories were enriched, particularly in categories related to signal transduction (mTOR signaling, ErbB signaling, MAPK signaling, etc.), synaptic categories (dopaminergic synapse, axon guidance, glutamatergic synapse, serotonergic synapse, neurotrophin signaling pathway), and many cancer-related categories (Fig. 3). The gene discussed is EGFR; the disease is cancer.
