Why Identical Genes Lead to Different Diseases: A New Foundational Model of Human Susceptibility

This paper introduces a breakthrough model explaining why genetically similar—or even nearly identical—individuals develop completely different diseases. Using a high-resolution emergent-field simulation, the study reveals that disease does not originate solely from genes or environment, but from the stability of the entire biological interaction architecture. Even a 1% difference in environmental exposure can reshape systemic coherence and produce opposite health outcomes. The work provides the first computational demonstration that disease susceptibility is determined by a person’s unique 60-node emergent structure—a stability map that dictates how their system absorbs or amplifies microscopic perturbations. This framework resolves long-standing biological paradoxes, including twin disease divergence, variable mutation expression, and unpredictable immune disorders. The paper proposes a new foundation for personalized medicine, where predicting and preventing disease becomes possible by analyzing system stability rather than genetic content alone.
