KEGG and GO enrichment analyses were conducted in David, suggesting that SNORD1A co‐expression genes are mostly involved in Ribosome, Huntington's disease, Pyrimidine metabolism, Parkinson's disease, Ribosome biogenesis in eukaryotes, RNA polymerase, Purine metabolism, Metabolic pathways, Oxidative phosphorylation, RNA transport for KEGG; rRNA processing and some biological activities related to mitochondrion for BP; Ribosome and Mitochondrion for CC; Poly(A) RNA binding and Structural constituent of ribosome for MF; NMYC, USF and NRF2 for TF (Figure 6). This evidence concerns the gene SNORD1A and Parkinson disease.
