NHIP and Parkinson disease: KEGG gene set enrichment analysis [55] showed enrichment for brain disorders, including Parkinson’s, Alzheimer’s, and Huntington’s diseases and metabolism, such as fatty acid metabolism and drug metabolism (Additional File 3: Fig. S38, KEGG enrichment statistics are in Additional File 24: Table S23), further demonstrating the relevance of NHIP regulated genes to brain functions.
