Cross-omic dissection reveals locus-specific heterogeneity and antagonistic pleiotropy between Alzheimer's disease and type 2 diabetes
This study employs an integrative cross-omic framework to demonstrate that the genetic relationship between Alzheimer's disease and type 2 diabetes is characterized not by a simple shared-risk model, but by locus-specific heterogeneity and antagonistic pleiotropy, where shared genetic signals often exert opposing effects on the two diseases.
