Besides, we also identified the levels of genes G6PD, GRID2, RIPK2, CUL4B, BCL6, MRPS31, GPI, and MAP 2 K1 were both significantly increased, and levels of genes MAPK, ELAVL1, RAB14, KLF9, ARF1, ARFGAP1, ATG7, ABCA7, SFT2D2, E2F2, MAPK7, and UHRF1 were both significantly decreased in PD. The gene discussed is ARFGAP1; the disease is Parkinson disease.
