DeCure's autonomous Neuro AI scientist is researching a drug-repurposing hypothesis for Charcot-Marie-Tooth disease type 5 — screening already-approved drugs against its 3-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 type 5 maps to a 3-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 type 5 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
mitofusin 2 (MFN2) — MFN2 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
In a 2023 retrospective study of 64 patients with suspected Charcot-Marie-Tooth disease, 25 (39%) received a molecular diagnosis by multiplex ligation probe amplification. Among 50 patients who then underwent next-generation sequencing for targeted gene panels, 18 (36%) had pathogenic or likely pathogenic variants. Whole-exome sequencing was performed on five patients with normal next-generation sequencing results, yielding an 80% diagnostic rate, which was higher in the childhood group. The authors note that patients without a molecular diagnosis persist across the literature, suggesting undiscovered genes or mechanisms.
A 2011 report describes the development of the CMT Pediatric Scale (CMTPedS), a multidimensional scale intended to measure disease severity in children with all types of CMT aged 3 to 17 years. The scale covers eight domains: symptoms, foot and ankle involvement, lower limb sensation, hand dexterity and strength, balance, and motor function. Inter-rater reliability from four international centres assessing eight children with CMT was good to excellent (ICC2,4 0.78–0.99). A multicentre natural history study had recruited 90 children at the time of publication. The authors planned to use the final CMTPedS as the primary outcome in clinical trials of podiatric, pharmacological and surgical interventions.
A 2022 case report describes a novel mutation in the MPZ gene causing early-onset but slow-progressive Charcot-Marie-Tooth disease in a Russian family. No drug intervention or treatment outcome is reported in this paper.
No abstract in this set reports a drug trial, a repurposed compound, or any treatment outcome for Charcot-Marie-Tooth disease type 5. What is missing is any funded clinical trial of a pharmacological intervention for this specific subtype, a validated outcome measure sensitive to change over short periods, and a clear stratification of patients by genetic subtype and disease stage.

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.
AbstractCharcot-Marie-Tooth disease (CMT) encompasses the heritable motor and sensory neuropathies that comprise most of the inherited peripheral neuropathies. Due to the great genetic heterogeneity of the condition, it can be difficult to determine what type of CMT a person has. The major phenotypic features of the CMT subtypes are delineated, as well as recommendations for focused genetic testing.

High diagnostic yield with algorithmic molecular approach on hereditary neuropathies
AbstractOBJECTIVE: Charcot-Marie-Tooth disease covers a group of inherited peripheral neuropathies. The aim of this study was to investigate the effect of targeted next-generation sequencing panels on the molecular diagnosis of Charcot-Marie-Tooth disease and its subtypes in routine clinical practice, and also to show the limitations and importance of next-generation sequencing in the diagnosis of Charcot-Marie-Tooth diseases. METHODS: This is a retrospective study. Three different molecular methods (multiplex ligation probe amplification, next-generation sequencing, and whole-exome sequencing) were used to detect the mutations related to Charcot-Marie-Tooth disease. RESULTS: In total, 64 patients (33 males and 31 females) with suspected Charcot-Marie-Tooth disease were analyzed for molecular etiology. In all, 25 (39%) patients were diagnosed by multiplex ligation probe amplification. With an extra 11 patients with normal PMP22 multiplex ligation probe amplification results that were consulted to our laboratory for further genetic analysis, a total of 50 patients underwent next-generation sequencing for targeted gene panels associated with Charcot-Marie-Tooth disease. Notably, 18 (36%) patients had pathogenic/likely pathogenic variants. Whole-exome sequencing was performed on five patients with normal next-generation sequencing results; the diagnostic yield by whole-exome sequencing was 80% and it was higher in the childhood group. CONCLUSION: The molecular etiology in Charcot-Marie-Tooth disease patients can be determined according to pre-test evaluation, deciding the inheritance type with pedigree analysis, the clinical phenotype, and an algorithm for the genetic analysis. The presence of patients without a molecular diagnosis in all the literature suggests that there are new genes or mechanisms waiting to be discovered in the etiology of Charcot-Marie-Tooth disease.

Development, reliability and validity of the Charcot‐Marie‐Tooth disease Pediatric Scale (CMTPedS)
AbstractCharcot-Marie-Tooth disease (CMT) causes peripheral nerve demyelination, progressive foot weakness, cavus deformity, difficulty walking and sensory loss. There is a need for accurate, sensitive and disease-relevant measures of young children through to adolescents with CMT to enable accurate assessment of baseline performance, monitor disease severity longitudinally, and determine responses to existing and novel foot and ankle interventions. Our objective was to develop a multidimensional scale to measure disease severity of children with CMT, known as the CMT Pediatric Scale (CMTPedS). The CMTPedS has undergone a thorough development process: (1) definition of the construct; (2) generation of the item pool; (3) choice of scoring format; (4) peer-review (face validity); (5) pilot testing; (6) standardised training; (7) inter-rater reliability of four international centres assessing eight children with CMT; (8) multicenter implementation. Findings of the development process: (1) the CMTPedS is a composite scale with broad application to measure disease severity of childhood CMT with eight domains capturing symptoms, foot/ankle involvement, lower limb sensation, hand dexterity/strength, balance, motor function; (2) a large pool of items generated from the literature were reduced based on disease-specificity, functional/patient-relevance, reliability/validity, published norms, test duration and ease of interpretation; (3) items collapsed to 5-point Likert scales using z-scores based on age/gender norms; (4) quality, appropriateness and suitability of items peer-reviewed by 23 expert clinicians/researchers/patient representatives at the 168th European Neuromuscular Centre International Workshop; (5) pilot-tested on four children with CMT to check for administration problems, item instructions, order and duration; (6) clinicians from USA, UK, Italy and Australia trained through workshops, online manual and video resources; (7) all items exhibited good to excellent inter-rater reliability (ICC2,40.78-0.99) (8) a multicenter natural history study of children with all types of CMT aged 3-17 years is underway, with 90 children recruited to date. Application and psychometric validation of the CMTPedS continues. We plan to apply the final CMTPedS as the primary outcome in clinical trials of podiatric, pharmacological and surgical interventions.
