In Gaucher disease OMIM 230800 (GBA1, OMIM 230800), 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: ✓ Recovers an existing standard. 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 0.5011, γ 1.4158, spinodal 0.6484). 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 Gaucher disease OMIM 230800 is an R19 double-well emerged from the real proximal-promoter DNA of GBA1. Its geometry is fixed by measured stiffness γ (never fitted); the numbers below are read directly off that cusp.

Chemistry feasibility (DIRECTION only [O]). small-molecule recrossing of the fold is geometrically harder (barrier 0.5011 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 gamma-restore (stabiliser / pharmacological chaperone).
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 GBA1 (raising the switch drive) does NOT move the DOWN [F] switch toward the healthy branch in a GBA1-deficient model, the h-restore(supply) lever is refuted for this axis.
Mechanism. stiffen the switch: stabilise the residual product so the healthy well re-deepens
Applies to. MISSENSE / residual-function alleles only
re-enlarges spinodal/barrier; needs a partially-functional allele
Falsifier. If a folding-stabiliser/chaperone does NOT re-deepen the healthy well for a residual GBA1 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
✓ Agreement with established practice. The corrective direction derived here (raise s toward ON branch) independently matches an agent already in clinical use for this disease: enzyme replacement (imiglucerase, velaglucerase alfa, taliglucerase alfa). The geometry recovered known medicine — this is a validation signal for the logic, not a new treatment claim by this kit.
Existing agents whose known action is direction-concordant with the derived lever (status as pinned in the corpus; no dose, no efficacy magnitude).
⚠ Mechanism-direction only — do not self-administer; no dose (unvalidated; set by a physician / national authority); not an approved use.
Direction-only candidate leads (corpus join)
Each lead is surfaced only because its known mechanism points the same way as the derived lever, and each comes with a source and a falsifier. None is a treatment.
ambroxol○ novel leaddir: stabilise · approved
Class. pharmacological chaperone of glucocerebrosidase (repurposed mucolytic)
Mechanism. A widely-approved mucolytic that also acts as a mixed-type pharmacological chaperone of acid beta-glucocerebrosidase, binding mutant enzyme at neutral pH, assisting its folding and lysosomal trafficking, and raising residual activity for several missense GBA1 variants. Direction: stabilise / re-deepen the residual glucocerebrosidase fold. Allele scope: residual / chaperonable-missense only -- it needs a foldable enzyme, so it cannot rescue a null allele. Gene-specific to GBA1. Repurposing lead: approved as a mucolytic, not approved for Gaucher disease -- a direction-only, untested [O] hypothesis for the Gaucher fold.
Prior-art. Ambroxol is an approved mucolytic but is NOT approved for Gaucher disease; it is under clinical investigation as a glucocerebrosidase chaperone (notably the neuronopathic form). Direction-only, untested for the Gaucher fold here.
Safety (qualitative; no magnitude). post-marketing safety profile on record as a mucolytic (long-marketed in the EU and Asia); not approved for Gaucher disease; qualitative; no magnitude
Falsifier. If ambroxol (a gene-specific stabilise agent) does NOT re-deepen the healthy well / restore thermostability for a RESIDUAL GBA1 missense allele in a gaucher_disease model -- i.e. produces no rescue beyond what a null allele shows -- the gamma-restore(stabilise) direction is refuted for ambroxol here. Null / large-deletion alleles are excluded by construction.
Source: Approved mucolytic label (EU/Asia); clinical-trial activity: ambroxol in neuronopathic Gaucher disease (not approved for Gaucher)
⚠ Mechanism-direction only — do not self-administer; no dose (unvalidated; set by a physician / national authority); not an approved use.
Class. broad-spectrum chemical chaperone / proteostasis modulator
Mechanism. Lowers endoplasmic-reticulum stress, induces folding chaperones, and rescues secretion/thermostability of diverse misfolded MISSENSE proteins (documented for CFTR-F508del, myocilin, type-III collagen, protein C, aquaporin-2, among others). Direction: stabilise / re-deepen the fold. Allele scope: residual / missense only — cannot rescue an absent (null) product, and rescue depends on the specific allele. LOW fold-specificity: a broad modulator, not a target-specific stabiliser.
Prior-art. Broad chemical chaperone; no approved indication for this specific rare disease, so the direction match is a speculative, untested hypothesis. (These agents' actual approvals -- urea-cycle disorders for 4-PBA; cholestatic liver disease and gallstone dissolution for UDCA -- are not among the diseases they surface against here, so no broad pair qualifies as a rediscovery.)
Safety (qualitative; no magnitude). post-marketing safety profile on record (approved for urea-cycle disorders; qualitative; no magnitude)
Falsifier. If sodium phenylbutyrate (4-PBA) (a broad stabilise agent) does NOT re-deepen the healthy well / restore thermostability for a RESIDUAL GBA1 missense allele in a gaucher_disease model -- i.e. produces no rescue beyond what a null allele shows -- the gamma-restore(stabilise) direction is refuted for sodium phenylbutyrate (4-PBA) here. Null / large-deletion alleles are excluded by construction.
Class. bile-acid chemical chaperone / ER-stress reducer
Mechanism. Bile-acid chemical chaperone that reduces endoplasmic-reticulum stress and assists folding of misfolded proteins; the taurine conjugate (TUDCA) is the more-studied chaperone form. Direction: stabilise the fold. Allele scope: residual / missense only. LOW fold-specificity.
Prior-art. Broad chemical chaperone; no approved indication for this specific rare disease, so the direction match is a speculative, untested hypothesis. (These agents' actual approvals -- urea-cycle disorders for 4-PBA; cholestatic liver disease and gallstone dissolution for UDCA -- are not among the diseases they surface against here, so no broad pair qualifies as a rediscovery.)
Safety (qualitative; no magnitude). post-marketing safety profile on record (approved for primary biliary cholangitis and gallstone dissolution; qualitative; no magnitude)
Falsifier. If ursodeoxycholic acid (UDCA; taurine conjugate TUDCA) (a broad stabilise agent) does NOT re-deepen the healthy well / restore thermostability for a RESIDUAL GBA1 missense allele in a gaucher_disease model -- i.e. produces no rescue beyond what a null allele shows -- the gamma-restore(stabilise) direction is refuted for ursodeoxycholic acid (UDCA; taurine conjugate TUDCA) here. Null / large-deletion alleles are excluded by construction.
