Description
The authors reveal an extensive network of direct protein-protein interactions and identify second proteins/transcripts as causal mediators of distant pQTL effects. The mechanistic basis of how these interaction networks propagate genetic effects across the proteome is not elucidated, representing a critical gap for understanding disease susceptibility networks.
