MAPT and Alzheimer disease: Furthermore, patterns of shared colocalized signals across brain tissues highlight potential clues to AD or neurodegenerative disorder pathway perturbations, and functional enrichment analysis shows these colocalized genes are related to tau protein binding, amyloid‐β regulation, immune pathways, platelet activation and signaling, neutrophil degranulation, AD disease pathways, protein metabolism, and signal transduction (Figure 6C).
