Genetically Proxied Angiotensin‐Converting‐Enzyme Inhibition is Potentially Causal for Alzheimer Disease: A Mendelian Randomization Study

Angiotensin‐converting enzyme (ACE) has been implicated in the pathogenesis of Alzheimer disease (AD), in which ACE plays a role in metabolizing Amyloid Beta (AB). Genetic variants in the ACE locus have also been associated with AD. The effect of ACE inhibitors on AD risk remains unclear. We sought to investigate the potential causal relationship between ACE inhibition and AD and other neurodegenerative disorders using a mendelian randomization (MR) approach.
