Triadic Genomic Regulation Framework for Autism: Mutation, Epigenetic Modulation, and Developmental Programs

This work proposes a triadic genomic regulation framework for autism that integrates three interacting layers of biological control: genetic mutation, epigenetic modulation, and developmental programs. The analysis synthesizes findings from molecular genetics, neurodevelopment, and systems biology to demonstrate how these layers jointly shape neurodevelopmental trajectories. The framework explains why heterogeneous genetic variants can converge on similar phenotypic outcomes, how environmental and epigenetic factors modulate risk, and why developmental timing plays a decisive role in the emergence of autistic traits. The study argues that autism cannot be understood through single‑factor models and instead requires a multi‑level regulatory perspective that captures dynamic interactions across biological scales. This conceptual model provides a foundation for future research on individualized risk profiles, mechanistic pathways, and targeted intervention strategies.
