DeCure for Charcot-Marie-Tooth disease axonal type 2F
DeCure's autonomous Neuro AI scientist is researching a drug-repurposing hypothesis for Charcot-Marie-Tooth disease axonal type 2F — screening already-approved drugs against its 1-gene Open Targets disease module to publish open-access research. Research is fast; the path to publication is funded in milestone stages.
Disease moduleCharcot-Marie-Tooth disease axonal type 2F maps to a 1-gene Open Targets module — the target space DeCure's AI scientist screens approved drugs against.
DeCure.ai methodSignature reversal (LINCS) plus network proximity (STRING) rank already-approved drugs likely to perturb this module — the same engine that produces DeCure.ai's repurposing hypotheses.
Repurposing thesisScreening approved medicines against this disease module, then publishing the evidence for the strongest candidate. Known pharmacology and human exposure data make the first question sharper — they do not establish safety or efficacy in a new indication.

Current lead
No approved-drug candidate for charcot-marie-tooth disease axonal type 2f is corroborated in the literature DeepSearch retrieved. Some conditions are managed with non-pharmacological care — a device, surgery or physical therapy — rather than a medicine; that may be the case here, or the literature we found may simply be too sparse yet to support a drug-repurposing angle.
Molecular view
heat shock protein family B (small) member 1 (HSPB1) — HSPB1 is one of the genes genetically linked to this disease in Open Targets — shown as context, not as a drug target we're pursuing: no approved-drug candidate for this disease is yet corroborated in the literature we found.

What the evidence adds up to
Two novel mutations in the dynamin-2 (DNM2) gene were found in two families with purely axonal Charcot-Marie-Tooth disease (CMT) and no clinical evidence of primary myopathy. The mutations were identified by screening exons 13 through 16 of DNM2, which encode the pleckstrin homology domain, in a large series of CMT patients who had a broad range of nerve conduction velocities and no mutations in more common genes. The authors concluded that patients with axonal CMT type 2 neuropathy without mutations in more common genes should be investigated for DNM2 pleckstrin homology domain mutations.
A separate report described a German patient with CMT2 carrying a spontaneous mutation (c.281G→A) in the mitofusin 2 (MFN2) gene. The patient presented with early-onset CMT that was not associated with central nervous system pathology. The disease course was rapidly progressive in the first years and slowed afterwards. The authors suggested that single patients with early-onset axonal polyneuropathies should be screened for MFN2 mutations. A later 2025 case report described phenotypic heterogeneity in CMT2A associated with the c.1091G>C (p.Arg364Pro) missense mutation in MFN2, noting that more than 100 missense mutations in this gene have been registered and that clinical presentation varies depending on the specific substitution.
A 2019 review noted that more than 90 causative genes for CMT have been identified, that previous animal studies reported some molecules to have therapeutic effects on specific CMT subtypes depending on the underlying genetic cause, and that recent investigations on induced pluripotent stem cells expanded the possibility of both patient-specific cell therapy and drug discovery. A 2024 review stated that despite significant progress, CMT remains a difficult problem in terms of accurate diagnosis and effective treatment. No drug repurposing data, no clinical trial results for any drug, and no survival or response rate numbers appear in any of these abstracts. What is still missing is any clinical evidence that a specific drug alters the course of CMT2F, as well as the trial designs, funding, and patient stratification needed to test such interventions.

Two novel mutations in dynamin-2 cause axonal Charcot–Marie–Tooth disease
AbstractBACKGROUND: Recently, mutations affecting different domains of dynamin-2 (DNM2) were associated alternatively with autosomal dominant centronuclear myopathy or dominant intermediate (demyelinating and axonal) Charcot-Marie-Tooth disease (CMT) type B. OBJECTIVE: To assess the etiologic role of DNM2 in CMT. METHODS: We performed a mutational screening of DNM2 exons 13 through 16 encoding the pleckstrin homology domain in a large series of CMT patients with a broad range of nerve conduction velocities and without mutations in more common genes. RESULTS: We identified two novel DNM2 mutations that cosegregated with purely axonal CMT in two pedigrees without clinical evidence of primary myopathy. CONCLUSION: Patients with axonal Charcot-Marie-Tooth disease type 2 neuropathy without mutations in more common genes should undergo investigation for DNM2 pleckstrin homology.
AbstractCharcot-Marie-Tooth disease (CMT) has been classified into two types: demyelinating forms (CMT1) and axonal forms (CMT2). Mutations in the CMT2A locus have been linked to the KIF1B and the mitofusin 2 (MFN2) genes. Here, we report a German patient with CMT2 with an underlying spontaneous mutation (c.281G-->A) in the MFN2 gene. Clinically, the patient presented with early-onset CMT that was not associated with additional central nervous system pathology. The disease course was rapidly progressive in the first years and slowed afterwards. We also suggest that single patients with early-onset axonal polyneuropathies should be screened for MFN2 mutations.

Clinical and genetic aspects of Charcot-Marie-Tooth disease subtypes
AbstractCharcot-Marie-Tooth disease (CMT) is one of the most common inherited neuropathies and is both genetically and clinically heterogeneous, with variable inheritance modes. With regard to clinical and genetic aspects, CMT is divided into several subtypes, including CMT1, CMT2, CMT3, CMT4, CMT5, CMT6, X-linked CMT, and intermediate CMT. Up to date, more than 90 causative genes for CMT have been identified. Furthermore, previous animal studies reported some molecules to have therapeutic effects on specific CMT subtypes, depending on the underlying genetic cause. Therefore, accurate genetic diagnosis is of crucial importance when performing customized therapy. Finally, recent investigations on induced pluripotent stem cells expanded the possibility of both patient-specific cell therapy and drug discovery. The current review focuses on the latest classification updates for accurate CMT diagnosis.

Phenotypic heterogeneity of Charcot–Marie–Tooth type 2A disease associated with the c.1091G>C missense mutation (p.Arg364Pro) in the MFN2 gene
AbstractCharcot–Marie–Tooth disease belongs to the group of genetically and phenotypically heterogeneous sensory-motor polyneuropathies. Charcot–Marie–Tooth disease type 2A (CMT2A) is the most common axonal form of the disease caused by mutations in the mitofusin-2 gene (MFN2). More than 100 missense mutations in this gene have been registered to date. Many studies have demonstrated the variability of clinical presentation depending on the specific localization of the substitution. The presented clinical case shows the peculiarities of the phenotype of a patient with CMT2A disease associated with the c.1091G>C (p.Arg364Pro) missense mutation in the MFN2 gene.
