SNAP47 and Parkinson disease: Moreover, the KEGG pathways (e.g., parkinson disease, cholinergic synapse, glutamatergic synapse) and GO terms (e.g., positive regulation of neuron differentiation, forebrain neuron differentiation, central nervous system neuron axonogenesis, regulation of neurogenesis) associated with nerve were detected, involving a set of genes (e.g., PTPN21, ROBO1, HOMER1, MAGI2, SLC1A3, NRG3, SNAP47, CTNNA2, ADGRL3).
