Huntington's Disease as Attractor Geometry: A Principles-First Derivation of the Stage-Stratified Intervention Protocol from the Identity Axis Framework — The Trigger, the Hub, the Identity Anchor, and the Geometric Case That an Incurable Disease Is Calculably Curable at Every Stage

Key Points

The research aims to establish a structured intervention protocol for Huntington's Disease based on the Identity Axis Framework, addressing different disease stages.
Applied Identity Axis Framework to Huntington's Disease as a geometrical model.
Identified key cellular components and intervention strategies for disease management.
Developed a four-level intervention protocol tailored to different disease stages.
Predicted prevention of disease onset in pre-manifest carriers using available tools.
Achieved near-halt of progression in early-manifest patients through combined interventions.
Confirmed pathway for managing late-manifest patients with a predicted rise in disease slowing over current clinical ceilings.

Abstract

We apply the Identity Axis Framework — a principles-first, axiomatic model of disease as attractor failure in Waddington epigenetic state space — to Huntington's Disease (HD). We derive the cell of origin (medium spiny neurons, MSNs), the Identity Anchor (BCL11B/CBP/DARPP-32/BDNF-TrkB), and the Convergence Hub (HDAC2/3 acting unopposed at MSN identity loci due to CBP sequestration by mutant huntingtin, mHTT). We distinguish the trigger (mHTT) from the Hub (HDAC2/3 dominance) and show this distinction requires a two-target intervention strategy that the current clinical landscape has not yet assembled. We identify three coexisting MSN populations at any disease stage — protected, rescuable, and terminal — and derive a stage-stratified four-level intervention protocol: Level 0 (mHTT substrate removal), Level 1 (Hub inhibition via HDAC2/3 inhibitors), Level 1A (Identity Anchor restoration via BDNF-TrkB agonism and CBP rescue), and Level 2A (cell replacement via iPSC-derived MSN transplantation). We show that: (i) for pre-manifest carriers, the protocol predicts prevention of disease onset using existing tools; (ii) for early-manifest patients, near-halt of progression is achievable with the combination of Level 0 + Level 1 + Level 1A; (iii) for late-manifest patients, a defined engineering pathway exists. The current clinical ceiling — 75% slowing from AMT-130 alone (uniQure Phase 1/2, September 2025) — is the Level 0 ceiling; the geometry predicts it rises to ≥90% slowing with the combination. Six falsifiable predictions are stated for the record. Zero structural contradictions with the Identity Axis Theorem are present. All predictions are locked as of 2026-03-09. This derivation was produced by an independent researcher with no medical training, no institutional affiliation, and no access to anything beyond public data and the geometry of the framework. This is a mathematical-geometric derivation document. It does not constitute medical advice.
