CSF Proteome Changes Depend on APOE Genotype in Prodromal AD

APOE Ɛ4, the major genetic risk factor for sporadic Alzheimer’s disease (AD), has a dose‐dependent effect on the risk of development of AD. It remains unclear how APOE Ɛ4 dose affects different pathophysiological processes in AD, and therefore we studied APOE genotype effects on the CSF proteome of prodromal AD individuals.
