Current lead

No approved-drug candidate for intellectual disability, autosomal dominant 38 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

eukaryotic translation elongation factor 1 alpha 2 (EEF1A2)EEF1A2 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

A 2011 study identified a missense mutation (p.R617Q) in the MED23 gene that cosegregated with nonsyndromic autosomal recessive intellectual disability in one family. The mutation impaired the response of JUN and FOS immediate early genes to serum mitogens by disrupting the interaction between enhancer-bound transcription factors and the Mediator complex. Transcriptional dysregulation of these same genes was also observed in cells from patients with other neurological disorders linked to mutations in other Mediator subunits or interacting proteins. The authors suggested that altered immediate early gene expression might be a common molecular hallmark of cognitive deficit, but this remains a hypothesis based on a single family and cell-line data.

A 2021 case report described a patient with intellectual disability who carried a de novo heterozygous nonsense c.40C>T (p.Arg14X) variant in the TRIP12 gene, classified as pathogenic under ACMG criteria. This variant had not been previously recorded in the Human Gene Mutation Database. The patient was diagnosed with autosomal dominant intellectual disability due to this TRIP12 variant. The report provides no data on treatment or outcomes beyond the genetic diagnosis.

A 2011 review on fragile X syndrome noted that intellectual disability was then considered an immutable condition and that existing medical practices aimed only at symptom relief, not at altering underlying cognitive deficits. The review expressed optimism that pharmaceutical therapies for fragile X syndrome might become a benchmark for CNS drug discovery, but it offered no clinical trial results or evidence that any drug had altered cognitive outcomes.

A 2021 review of autosomal recessive intellectual disability stated that most published cohort genetic studies on intellectual disability have revealed the important contribution of de novo variants, but that autosomal recessive forms account for most molecular bases in inbred populations. The review did not report any therapeutic interventions or drug trials.

<i>MED23</i> Mutation Links Intellectual Disability to Dysregulation of Immediate Early Gene Expression

AbstractMED23 is a subunit of the Mediator complex, a key regulator of protein-coding gene expression. Here, we report a missense mutation (p. R617Q) in MED23 that cosegregates with nonsyndromic autosomal recessive intellectual disability. This mutation specifically impaired the response of JUN and FOS immediate early genes (IEGs) to serum mitogens by altering the interaction between enhancer-bound transcription factors (TCF4 and ELK1, respectively) and Mediator. Transcriptional dysregulation of these genes was also observed in cells derived from patients presenting with other neurological disorders linked to mutations in other Mediator subunits or proteins interacting with MED. These findings highlight the crucial role of Mediator in brain development and functioning and suggest that altered IEG expression might be a common molecular hallmark of cognitive deficit.

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.

Homozygous <i>MEFV</i> Gene Variant and Pyrin-Associated Autoinflammation With Neutrophilic Dermatosis

AbstractIMPORTANCE: Pyrin-associated autoinflammation with neutrophilic dermatosis (PAAND) is a monogenic autoinflammatory disorder with autosomal dominant inheritance and has been associated with monoallelic p.Ser242Arg and p.Glu244Lys variations in the MEFV gene. This dermatosis shares clinical features and pathogenesis with familial Mediterranean fever, although it is a clinically distinct entity. OBJECTIVE: To identify the genetic basis of PAAND in a consanguineous family with 2 affected children and to prescribe an effective genotype-guided treatment. DESIGN, SETTING, AND PARTICIPANTS: This case series study examined 2 siblings who presented with clinical features of PAAND. We sought the genetic basis of this disease with trio whole exome sequencing (trio-WES). Genome-wide homozygosity mapping provided additional evidence for causality of a sequence variant identified by trio-WES. MAIN OUTCOMES AND MEASURES: Association of a biallelic MEFV variation with a new form of autosomal recessive PAAND was documented by genetic analysis. Response to treatment with colchicine and a low-dose steroid was assessed clinically and experimentally. RESULTS: Two siblings, a girl (proband; age 5 years) and a boy (age 2.5 years) of Iranian-Azeri ancestry born to first-cousin consanguineous parents presented with clinical features of PAAND-recurrent episodes of maculopapular and pustular rash, gastrointestinal involvement resembling inflammatory bowel disease, and intussusception with generalized mesenteric lymphadenitis. A trio-WES test detected a previously unreported homozygous missense variation, p.Ser242Gly, in both patients' MEFV gene. Genome-wide homozygosity mapping revealed shared regions of homozygosity in the patients' DNA, including 1 on chromosome 16 harboring MEFV. Whole transcriptome sequencing by RNA-sequencing revealed that the variant MEFV transcript, among the inflammasome-associated transcripts, was most upregulated, and the cell-cell receptor interaction and innate immune system pathways were most positively enriched. Under the guidance of MEFV genotype, treatment with colchicine (1 mg/d) and low-dose prednisolone (2.5 mg every other day) was started, and the patients responded well. CONCLUSIONS AND RELEVANCE: This case series study demonstrated successful genotype-guided treatment with colchicine and low-dose prednisolone, a low-cost therapeutic option with minimal adverse effects, in patients with a novel form of autosomal recessive PAAND. This case report examines the genetic basis of PAAND in a consanguineous family with 2 affected children and seeks to prescribe an effective genotype-guided treatment.

[Intellectual disability due to heterozygous c.40C>T variant of TRIP12 gene in a patient].

AbstractOBJECTIVE: To explore the genetic basis for a patient with intellectual disability. METHODS: Whole exome sequencing and Sanger sequencing were carried out for the patient. The result was verified in her family. RESULTS: DNA sequencing revealed that the patient has carried a heterozygous nonsense c.40C>T (p.Arg14X) variant of the TRIP12 gene, which was de novo in origin. The variant was unrecorded in the Human Gene Mutation Database. Based on the American College of Medical Genetics and Genomics standards and guidelines, the variant was predicted to be pathogenic (PVS1+ PS2+ PP3). CONCLUSION: The patient was diagnosed with autosomal dominant intellectual disability due to heterozygous c.40C>T variant of the TRIP12 gene.

Review On Clinical And Molecular Genetics Of Autosomal Recessive Intellectual Disability

AbstractIntellectual disability (ID) is a relatively common phenotype with multiple etiologies. Recent progress in the genetics of ID greatly expanded our understanding of the biological defects underlying this clinical entity. While most published cohort genetic studies on ID revealed the important contribution of de novo (germline or postzygotic) variants, we focused in this study of autosomal recessive ID (ARID), that account for most of the molecular bases in ID cases in inbred populations. We discussed the current state of ARID from a clinical, molecular and genetics standpoints.

An overall review on intellectual disability disorder and its homoeopathic management

AbstractThe Intellectual Disability Disorder is found as a one of the clinical manifestations of the rare disorders which occupies a total prevalence of about 6 to 8% globally. The rare disorder is found to cause many of the chronic disabilities in which the intellectual disability disorder is one of them which has a drastic impact on the individual who is affected and their families and includes the health care system. The onset period of the rare disorder begins from the prenatal period into the late adulthood and it is being assessed that about the half of the individual affected are children [1]. The prime and the only purpose of this study undertaken is to find the effectiveness of the homoeopathic medicine in the treatment of the Intellectual Disability Disorder and also to alter their intellectual and the adaptive functions of the affected individual. The homoeopathic medicine will remove the disease from the root cause.

Behavioral and brain phenotypes of mouse models of Bardet-Biedl Syndrome

AbstractIntellectual disability (ID) is one of the most common neurodevelopmental disorders, affecting 1% of the population globally. Clinically, ID is characterized by a deficit in intellectual functioning and adaptive functioning. There are limited pharmacological interventions for ID, partially due to a poor understanding of ID and the heterogeneous nature of ID In addition, there are limited mouse models of ID.
