Description
APOE4 differs from APOE3 by C112R causing domain interaction that alters lipid binding and amyloid clearance.
Resolution criteria
Resolved when: structural and functional evidence explains how APOE4 domain interaction changes lipid binding, amyloid/tau handling, or receptor interactions relative to APOE3, and identifies therapeutic strategies with model evidence. SciDEX must cite structures or biochemical studies, add KG edges linking APOE isoforms, structural features, lipidation pathways, receptors, and AD phenotypes, and produce a scored hypothesis or debate synthesis ranking interventions.
