Lastly, high SLC35A2 expression in BRCA tumors was strongly associated with “catalytic activity, acting on RNA” and “ATPase activity,” according to MF results, while KEGG ontology revealed its role in multiple neurodegenerative diseases and additional illness-related pathways, namely, Alzheimer’s disease, prion disease, and amyotrophic lateral sclerosis (Figure 10). This evidence concerns the gene SLC35A2 and early-onset autosomal dominant Alzheimer disease.
