DeCure for Charcot-Marie-Tooth disease recessive intermediate D
DeCure's autonomous Neuro AI scientist is researching a drug-repurposing hypothesis for Charcot-Marie-Tooth disease recessive intermediate D — 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 recessive intermediate D 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 recessive intermediate d 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
cytochrome c oxidase subunit 6A1 (COX6A1) — COX6A1 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
Charcot-Marie-Tooth disease recessive intermediate D is one of many CMT subtypes. More than 90 causative genes for CMT have been identified as of 2019, and the genetic complexity is such that different mutations of the same gene produce a range of phenotypes, making a simple molecular classification difficult to use in practice. A 2023 retrospective study of 64 patients with suspected CMT used multiplex ligation probe amplification, next-generation sequencing, and whole-exome sequencing to find a molecular diagnosis. 25 patients (39%) were diagnosed by multiplex ligation probe amplification alone. Among 50 patients who then underwent next-generation sequencing for targeted CMT gene panels, 18 (36%) had pathogenic or likely pathogenic variants. Whole-exome sequencing on five patients with normal next-generation sequencing results gave an 80% diagnostic yield, higher in the childhood group. The study noted that patients without a molecular diagnosis remain in all the literature, suggesting undiscovered genes or mechanisms.
No abstract reports a clinical trial or any drug tested specifically for CMT recessive intermediate D. Animal studies have reported some molecules with therapeutic effects on specific CMT subtypes depending on the underlying genetic cause, but no such molecules are named in these abstracts, and no human efficacy data are provided. A 2007 review stated that animal models for the most common CMT subtypes were then available, but the focus remained on understanding pathomechanisms rather than on treatment. A 2019 review mentioned that induced pluripotent stem cells had expanded the possibility of patient-specific cell therapy and drug discovery, but again no concrete therapeutic results are given.
What is still missing for CMT recessive intermediate D specifically is any clinical trial data, any drug tested in patients, and even a clear molecular diagnosis in many cases. The genetic heterogeneity means that a therapy effective for one mutation may not work for another. Money for trials, a trial design that accounts for the slow progression and variable phenotypes, and better patient stratification by exact genetic cause are all absent. No drug can be recommended from these abstracts.

Hereditary neuropathies
AbstractPURPOSE OF REVIEW: The purpose of this review is to help neurologists understand new concepts in hereditary neuropathies, from the clinician's point of view, in the molecular era after the burst of information regarding peripheral nerve biology. RECENT FINDINGS: Recent studies have focused on understanding the pathomechanisms involved in hereditary neuropathies. In the past year identification of new genes has slowed down since scientists have concentrated more on the function of genes causing Charcot-Marie-Tooth disease and Schwann cell-axon interactions to reveal the molecular cell biology of the disease. Animal models for the most common subtypes of human Charcot-Marie-Tooth disease are now available. SUMMARY: Rapid advances in the molecular genetics and cell biology of hereditary neuropathies have highlighted the great genetic complexity of Charcot-Marie-Tooth disease. The evolution from a simple clinical classification to a complex molecular one has not facilitated our understanding of the disease. Moreover, the new molecular classification is not simple to use as different mutations of the same gene produce a range of phenotypes. The clinicians have to look for specific clinical and electrophysiological clues to direct the patient to appropriate genetic testing.

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.

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.
