Quick takeaways

  • The Apolipoprotein E4 (APOE4) gene is the most influential risk factor for late-onset Alzheimer's disease, contributing to over 50% of cases.
  • APOE4 variant has detrimental effects on cholesterol metabolism, immune function, blood-brain barrier integrity, and synaptic plasticity, increasing the risk of Alzheimer's and other impairments.

Genetics of Alzheimer's Disease: Apo E4 Gene

The podcast discusses the genetics of Alzheimer's disease, specifically focusing on the Apolipo gene E4 (Apo E4), which is the most influential genetic risk factor for late-onset Alzheimer's. The discussion covers the evolutionary aspects of Apo E proteins, the different isoforms of Apo E and their influence on Alzheimer's disease, the impact on lipid metabolism and immune function in the brain, and the latest evidence on the epigenetics of Apo E4.
