Classic EDS (COL5A1) OMIM 130000

In Classic EDS (COL5A1, OMIM 130000), the master switch sits on the ↓ DOWN branch ([F] forced below); the healthy state is the ON well. The forced corrective direction is to raise s toward ON branch (polarity: supply). Classification: — Honest hold (no matched agent). Direction only — no dose, no efficacy magnitude.

The disease maps to an R19 double-well whose corrective lever is read straight off the cusp (barrier 0.5847, γ 1.5293, spinodal 0.7279). The corrective direction is forced [F]; the agent names below are direction-concordant labels at grade [O] (no dose, no efficacy or safety magnitude). This is a research hypothesis offered to experts, not medical advice.

The emergence switch

The switch for Classic EDS is an R19 double-well emerged from the real proximal-promoter DNA of COL5A1. Its geometry is fixed by measured stiffness γ (never fitted); the numbers below are read directly off that cusp.

emergent axis: ↓ DOWN [F]
healthy branch: ON
lesion: LOF_null
γ (stiffness): 1.5293
barrier: 0.5847
spinodal: 0.7279
s_on / s_off: 1.2366 / -1.2366
fragility: 0.07
corrective polarity: supply
forced direction: raise s toward ON branch

Chemistry feasibility (DIRECTION only [O]). small-molecule recrossing of the fold is geometrically harder (barrier 0.5847 at neutral drive; lower barrier = smaller drive to supply). [O] -- no affinity/potency/dose/efficacy asserted.

The derived corrective lever

The cusp forces a corrective direction: raise s toward ON branch. This is the load-bearing output of the framework — it is [F] forced, and it is falsifiable. 2 lever families are derived; the lead is h-restore (drive modulator).

h-restore (drive modulator)sign: increasegeometric rank 0.07

Mechanism. supply / restore the positive drive (replace-or-agonise the missing competence)

Applies to. allele-agnostic (downstream/environmental tilt)

favoured when the switch is fragile -- a small drive shift recrosses the fold

Falsifier. If supplying/agonising dermal and connective-tissue type-V-collagen fibrillogenesis competence lost to the COL5A1 haploinsufficiency (raising the switch drive) does NOT move the DOWN [F] switch toward the healthy branch in a COL5A1-deficient model, the h-restore(supply) lever is refuted for this axis.

gamma-restore (stabiliser / chaperone)sign: Nonegeometric rank 0.00

Mechanism. N/A

Applies to. none (honest exclusion)

EXCLUDED: null allele -- no product to stiffen

Falsifier. If a folding-stabiliser/chaperone does NOT re-deepen the healthy well for a residual COL5A1 allele (no rescue that a null allele lacks), the gamma-restore lever is refuted; null alleles are excluded by construction.

Agents mapped onto the lever

Honest hold. The corrective direction is derived and falsifiable, but no approved direction-matched agent is mapped in the pinned corpus. The kit holds here rather than name a weak instance — an honest hold is a finding, not a failure.

Evidence & provenance

What is reproduced vs. cited for this page.
element	grade	basis
R19 switch & cusp geometry (this page)	[V] verified	emerged from measured promoter γ of `COL5A1`; deterministic, 2×sha256 identical
corrective direction	[F] forced	forced by the cusp sign; falsifiable (see lever falsifiers)
mapped agents / leads	[O] open	direction-concordance only; corpus-pinned (2026-06-21); no dose, no efficacy/safety magnitude

Reading the agent column. VALIDATION SIGNAL -- the agent is already approved / established standard for this disease, so the direction logic recovered known clinical practice. Not a new claim by this kit. GENUINE HYPOTHESIS -- no approved indication for this disease; the direction match is a direction-only, untested [O] lead. Basis field grades the evidence (investigational here / in a related condition / off-label / speculative).
