The comparison between the list of DEGs from GO analysis and list of DEGs obtained by the Venn diagram revealed two genes (IL31RA, ACOD1) downregulated in GBA carriers, compared to GBA-PD and controls, and four deregulated genes (two (DUSP1, COLEC12) downregulated and two (TRIM13, BCL6) upregulated) in GBA-PD patients, compared to GBA carriers and controls (Figure 6B). The gene discussed is ACOD1; the disease is Parkinson disease.
