DeCure for Intellectual developmental disorder, autosomal recessive 67
DeCure's autonomous Psychiatry AI scientist is researching a drug-repurposing hypothesis for intellectual developmental disorder, autosomal recessive 67 — 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 moduleIntellectual developmental disorder, autosomal recessive 67 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 intellectual developmental disorder, autosomal recessive 67 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.
What the evidence adds up to
The 2025 study reports a homozygous c.1693T>C;p.(Tyr565His) variant in the SLC6A17 gene in a Pakistani family with autosomal recessive intellectual disability. The index patient was the second child of healthy consanguineous parents with a history of intellectual disability. Whole exome sequencing identified the variant, which segregated with the phenotype in the extended family. The authors state this broadens the genotypic spectrum of SLC6A17 variants, but the abstract gives no data on treatment, response rates, or sample size beyond a single family.
A 2022 paper describes a child with global developmental delay, short stature, and epileptic seizures who carried a de novo pathogenic ZBTB18 frameshift variant. After treatment with levetiracetam and rehabilitation, seizures were controlled for nearly half a year, and psychomotor and language development improved. The authors note that among 28 children with ZBTB18 mutations, those with frameshift or nonsense mutations had more motor retardation, language delay, and epilepsy than those with missense mutations. This is a different gene and inheritance pattern (autosomal dominant) from the autosomal recessive condition in the query.
A 2012 case report on pyridoxine dependent epilepsy describes two sisters with the same ALDH7A1 mutations and early treatment with pyridoxine, thiamine, phenytoin and carbamazepine. Despite identical genetic background and early treatment, the older sister had moderate intellectual disability and could not live unattended, while the younger sister had only mild intellectual disability and lived independently. The authors conclude that disease manifestations vary widely even within the same family. This condition is not the same as autosomal recessive intellectual developmental disorder type 67.
A 2011 review on fragile X syndrome states that intellectual disability was long considered immutable but that scientific advances now suggest it may be treatable. It offers no concrete data on any specific drug or outcome for any patient population. No abstract in this set provides evidence for any drug that treats autosomal recessive intellectual developmental disorder type 67. What is missing is any clinical trial, any patient stratification by genotype, and any funding directed specifically at this rare disorder.

Fragile X Syndrome: An Update on Developing Treatment Modalities
AbstractIntellectual disability (ID; mental retardation) is considered an immutable condition. Current medical practices are aimed at relieving symptoms and not at altering the underlying cognitive deficits. Scientific advancements from the past decade have led to the exciting possibility that ID may now be treatable. Moreover, pharmaceutical therapies targeting the most common form of inherited ID, Fragile X syndrome (FXS), may become the new benchmark for central nervous system (CNS) drug discovery: seeking cures for neurodevelopmental disorders.

Variability of Phenotype in Two Sisters with Pyridoxine Dependent Epilepsy
AbstractBACKGROUND: Pyridoxine dependent epilepsy (PDE) is characterized by neonatal epileptic encepahalopathy responsive to pharmacological doses of vitamin B6. Recently an autosomal recessive deficiency in Antiquitin (ALDH7A1), a gene involved in the catabolism of lysine has been identified as the underlying cause. CASE REPORT: In 21 and 23 year-old sisters, who had presented with neonatal / early infantile onset seizures, PDE was confirmed by elevated urinary alpha aminoadipic- 6- semialdehyde (α-AASA) excretion and compound heterozygosity for two known ALDH7A1 missense mutations. Although epilepsy was well controlled upon treatment with pyridoxine, thiamine, phenytoin and carbamazepine since early infancy, both had developmental delay with prominent speech delay as children. As adults, despite the same genetic background and early treatment with pyridoxine, their degree of intellectual disability (ID) differed widely. While the older sister's cognitive functions were in the moderate ID range and she was not able to live unattended, the younger sister had only mild ID and was able to live independently. CONCLUSION: Although seizures are a defining feature of PDE, other disease manifestations can vary widely even within the same family. Adult neurologists should be aware that the diagnosis of PDE can be delayed and PDE should be considered in the differential diagnosis of adults with seizure disorders dating from childhood.
[Analysis of clinical features and ZBTB18 gene variant in a child with autosomal dominant mental disorder type 22].
AbstractOBJECTIVE: To analyze the clinical characteristics and ZBTB18 gene variant in a child with epilepsy and global developmental delay. METHODS: Clinical data and laboratory examination of the patient were reviewed. Whole exome sequencing (WES) was also carried out for the family trio. RESULTS: The main manifestations of the child included global developmental delay, short stature, epileptic seizures. EEG revealed frequent occurrence of sharp (slow) waves in the right central region during sleeping, with sharp waves occasionally seen in the frontal and right posterior temporal regions. Cranial MRI has shown no obvious abnormality. WES has identified a de novo pathogenic variant in the ZBTB18 gene [NM_205768.3: exon 2: c.1282_1283del (p.Phe428Leufs*72)]. Based on the guidelines from American College of Medical Genetics and Genomics (ACMG), the variant was classified as pathogenic (PS2+PVS1_Moderate+PM2_Supporting). Following treatment with levetiracetam and rehabilitation, the seizures have been controlled for nearly half a year, with improvement of the psychomotor and language development. So far 28 children have been discovered with ZBTB18 gene mutations, and there was a significant difference in the clinical phenotypes of motor retardation, language retardation and epilepsy between those harboring frameshift/nonsense mutations and missense mutations. CONCLUSION: The c.1282_1283del (p.Phe428leufs *72) variant of the ZBTB18 probably underlay the autosomal dominant mental disorder type 22 in this child. Compared with missense mutations, frameshift/nonsense mutations may predispose more to motor retardation, delayed language development and epilepsy.
Biallelic Variant in <scp> <i>SLC6A17</i> </scp> in a Pakistani Family With Autosomal Recessive Intellectual Disability
AbstractAutosomal recessive intellectual disability affects 1%-3% of the general population and is a major concern in countries where consanguineous marriages are common. Mental retardation autosomal recessive 48 (MRT 48) (OMIM 616269) is a recessive syndromic disorder characterized by progressive tremors, speech impairment, and behavioral problems. In the present study, we highlight a family with a case of MRT 48. The index patient was second born to healthy consanguineous parents with a history of intellectual disability. Whole exome sequencing of the patient was performed, which revealed a homozygous c.1693T>C;p.(Tyr565His) variant in the SLC6A17 gene. The variant segregated in the extended family with the phenotype. This study broadens the genotypic spectrum of SLC6A17 variants.
