DeCure for Autosomal dominant nonsyndromic hearing loss 40
DeCure's autonomous Rare AI scientist is researching a drug-repurposing hypothesis for autosomal dominant nonsyndromic hearing loss 40 — 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 moduleAutosomal dominant nonsyndromic hearing loss 40 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 autosomal dominant nonsyndromic hearing loss 40 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
crystallin mu (CRYM) — CRYM 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
Hearing loss affects about 4% of people under 45 years of age. Approximately 30% of genetically determined deafness occurs in syndromic form and 70% in nonsyndromic form. Over 50% of hearing loss cases have a genetic background, with roughly 20% of hearing impaired patients suffering from autosomal dominant non-syndromic hearing loss, making it the second most common cause.
No abstracts in this set specifically address autosomal dominant nonsyndromic hearing loss 40 (DFNA40). The abstracts that discuss TMC1 gene variants describe autosomal recessive hearing loss DFNB7/11, not the dominant form. In three children from two non-consanguineous families with DFNB7/11, all showed prelingual, severe-to-profound hearing loss. After cochlear implantation, these three patients showed an excellent functional outcome, with speech perception, nonverbal cognition, and speech performance comparable to patients with DFNB1 deafness. The authors state their results do not support the variable auditory outcome reported in the literature.
One abstract mentions DFNA37, caused by COL11A1 variants, but this is a different genetic form of autosomal dominant hearing loss. No abstract provides any data on drug treatment, gene therapy, or pharmacological intervention for any form of autosomal dominant nonsyndromic hearing loss.
What is missing for autosomal dominant nonsyndromic hearing loss 40 specifically: no clinical trials, no identified drug candidates, no patient stratification data, and no funding directed at this particular genetic subtype. The basic molecular characterisation of the DFNA40 locus and its causative gene would need to be established before any therapeutic approach could be designed.

Vestibular and hearing loss in genetic and metabolic disorders
AbstractHearing loss affects about 4% of people under 45 years of age and comprises a broad spectrum of clinical presentations (congenital or late-onset, conductive or sensorineural, and syndromic or nonsyndromic). Approximately 30% of genetically determined deafness is reported to occur in syndromic form and 70% in nonsyndromic form. This review highlights recent advances in the molecular and genetic basis of hearing loss, which will help in understanding the biology of normal and abnormal hearing.
Supplementary Material for: Auditory Outcome after Cochlear Implantation in Children with DFNB7/11 Caused by Pathogenic Variants in <b><i>TMC1</i></b> Gene
Abstract<b><i>Introduction:</i></b> Non-syndromic hereditary hearing loss is characterized by extreme genetic heterogeneity. So far, more than 100 pathogenic or likely pathogenic variants in <i>TMC1</i> gene have been reported in patients with autosomal recessive hearing loss (HL) DFNB7/11. The prevailing auditory phenotype of individuals with DFNB7/11 is congenital, profound, bilateral HL, but the functional outcome after cochlear implantation (CI) described in the literature is variable. The objective of this work is to evaluate the auditory outcome after CI in pediatric patients with DFNB7/11, born to non-consanguineous parents. <b><i>Methods:</i></b> A retrospective analysis of genetic and audiological data of DFNB7/11 patients followed up in a single Italian otolaryngology clinic was performed. Cases with biallelic pathogenic variants in <i>TMC1</i> were selected from the cohort of children with non-syndromic hearing loss who had undergone CI and had been molecularly characterized by multigene panel testing. All patients underwent extensive audiological assessment, and the auditory outcome after CI was evaluated. <b><i>Results:</i></b> DFNB7/11 was diagnosed in a total of 3 patients from 2 non-consanguineous families; a novel disease-causing variant in <i>TMC1</i> was detected [c.962G>A p.(Trp321*)]. All the affected children showed the typical DFNB7/11 phenotype characterized by prelingual, severe-to-profound HL. The patients showed an excellent functional outcome after CI; speech perception, nonverbal cognition, and speech performance were comparable to those of patients with DFNB1 deafness. <b><i>Discussion/Conclusion:</i></b> Our results do not support the variable auditory outcome reported in the literature, which may be affected by several social and environmental factors and by the genetic background.

DFNA37 (autosomal dominant non-syndromic hearing loss 37) is caused by COL11A1 variants – confirmatory evidence by a novel splicing variant
AbstractHearing loss is an increasing burden in an aging society. Over 50 % of cases have a genetic background that are inherited in as autosomal dominant (DFNA), recessive (DFNB), X-linked (DFNX) and mitochondrial. Roughly 20 % of hearing impaired patients suffer from autosomal dominant non-syndromic hearing loss, making it the second most common cause. Most proteins are not specific to the inner ear. Mutations in genes coding for these proteins can cause syndromic hearing loss.
