MECANISMO DE DOENÇA

Albinism, oculocutaneous, 2

An autosomal recessive disorder in which the biosynthesis of melanin pigment is reduced in skin, hair, and eyes. Although affected infants may appear at birth to have complete absence of melanin pigment, most patients acquire small amounts of pigment with age. Visual anomalies include decreased acuity and nystagmus. The phenotype is highly variable. The hair of affected individuals may turn darker with age, and pigmented nevi or freckles may be seen. African and African American individuals may have yellow hair and blue-gray or hazel irides. One phenotypic variant, 'brown OCA,' has been described in African and African American populations and is characterized by light brown hair and skin color and gray to tan irides.

Emerging disease-modifying therapies for Angelman syndrome: A comprehensive review for pediatric neurologists.

Brain &amp; development2026 Mar 20

Angelman syndrome (AS), a rare neurogenetic disorder affecting approximately 1 in 15,000 live births, results from loss of functional UBE3A gene expression and manifests with severe developmental delay, intellectual disability, absent speech, ataxia, epilepsy, and distinctive behavioral features. Until recently, only symptomatic management was available. This review provides pediatric neurologists with a comprehensive, practice-oriented overview of emerging disease-modifying therapies for AS, focusing on therapeutic approaches advancing through clinical development. The molecular pathophysiology of AS, natural history considerations critical for trial interpretation, and the current evidence for antisense oligonucleotide (ASO) therapies (ION582, GTX-102/apazunersen, rugonersen), gene replacement approaches (MVX-220), and next-generation strategies including CRISPR-based gene editing, artificial transcription factors, small molecules, and novel delivery platforms are reviewed. ASO therapies targeting the UBE3A antisense transcript represent the most clinically advanced approach, with three candidates showing proof-of-concept efficacy in Phase 1/2 studies and two advancing to pivotal Phase 3 trials. Gene replacement therapy offers potential single-administration treatment but faces challenges regarding safety, immune responses, and durability. Next-generation approaches including CRISPR activation, epigenetic editing, and blood-brain barrier-penetrating delivery systems show preclinical promise. Critical challenges include outcome measurement limitations, genotype stratification, long-term safety monitoring, and ensuring equitable access. These advances herald a transformation in AS clinical care and represent a milestone in precision pediatric neurology.

Tuberous sclerosis complex.

Nature reviews. Disease primers2026 Mar 12

Tuberous sclerosis complex (TSC) is a rare genetic disease caused by heterozygous loss-of-function variants in TSC1 or TSC2. Patients present with benign tumours known as hamartomas in the brain, eyes, lungs, kidneys, heart and skin. Many hamartomas contain mosaic second hit variants in TSC1 or TSC2. The most disabling features of TSC include epilepsy and TSC-associated neuropsychiatric disorders (TAND) such as intellectual disability and autism spectrum disorder. Remarkable progress has been made both in understanding the pathogenesis of TSC and in its clinical management, largely due to the discovery of the link between TSC1 and TSC2 and the mechanistic target of rapamycin (mTOR) signalling pathway. TSC1 and TSC2 form a protein complex that inhibits mTOR. Naturally occurring inhibitors of mTOR (rapamycin) and its analogues, collectively known as rapalogues, have been used to test various hypotheses in preclinical models and are approved for the treatment of several manifestations of TSC. Approved drug treatments (rapalogues) exist for subependymal giant cell astrocytomas, renal angiomyolipomas, pulmonary lymphangioleiomyomatosis, facial angiofibromas and refractory seizures. However, there is still an unmet need for effective treatment of TAND and refractory epilepsy, despite the available medical and surgical options.

Unlocking the potential of multidisciplinary clinics to transform rare epilepsies care, insights, and research.

Frontiers in neurology2026

Multidisciplinary clinics (MDCs) improve care for patients with complex, comorbid conditions through coordinated, team-based care. Despite their potential, MDCs remain underutilized and understudied in pediatric neurology, particularly for individuals with rare, chronic epilepsies. The subject of MDCs in pediatric epilepsy was explored through two workshops and surveys of caregivers and clinicians. MDC models vary widely-from general clinics (e.g., neurology, genetics, and neuropsychology) to disorder-specific clinics with multisystemic specialists. Caregivers identified key barriers, including geographical distance, personal expense, and insurance prior authorization requirements, yet overall reported positive experiences-citing valuable opportunities to participate in research and meaningful changes to clinical care. Although the findings reflect responses from a predominantly white, higher-income, English-speaking group of caregivers recruited through patient advocacy networks-and may therefore carry certain biases-their perspectives remain broadly generalizable to prospective patients across diverse socioeconomic settings. Similarly, physicians identified funding and space as the primary barriers to establishing multidisciplinary clinics, yet a majority recognized the importance of advancing research, translational studies, and clinical trials. MDCs can improve care for patients with medically complex rare epilepsies by integrating the management of comorbidities. These clinics bring value to both rare patients and physicians by providing a setting for synergistic activities between clinical care, clinical trials, and research. To expand their impact, we recommend: (1) establishing more MDCs using sustainable models; (2) improving access to extend the reach of MDCs; (3) including key specialists for integrated care; (4) sharing disorder-specific expertise through collaboration and training; and (5) tracking standardized success measures to validate and scale these efforts.

Pharmacodynamics, Efficacy, and Safety of Intraputaminal Eladocagene Exuparvovec Administered to Pediatric Patients With Aromatic L-Amino Acid Decarboxylase Deficiency Using an MR-Compatible Cannula: 48 Weeks of Follow-Up.

Journal of inherited metabolic disease2026 Mar

Aromatic ʟ-amino acid decarboxylase (AADC) deficiency is a rare pediatric neurotransmitter disorder that typically necessitates lifelong care, and that carries a risk of childhood mortality. Eladocagene exuparvovec gene therapy is designed to restore AADC production. Study GT-002 (NCT04903288) is a phase 2, multicenter, open-label trial assessing the pharmacodynamics, safety, and efficacy of eladocagene exuparvovec administered to the putamen bilaterally in pediatric patients with AADC deficiency using a magnetic resonance (MR)-compatible cannula. Patients received eladocagene exuparvovec at 1.8 × 1011 vector genomes via the SmartFlow MR-compatible cannula in a single operative session. Endpoints include the change from baseline in cerebrospinal fluid homovanillic acid levels, motor milestone achievement, and safety. Here we report results from 48 weeks of follow-up. Mean (SD) cerebrospinal fluid homovanillic acid levels increased from baseline (22.5 [32.3] nmol/L; n = 13) to week 48 (55.3 [45.6] nmol/L; change from baseline: 28.3 [13.7] nmol/L; p = 0.0003; n = 9), indicating de novo dopamine production. At baseline (n = 13), all patients showed severe motor developmental delay; at week 48 (n = 12), nine achieved full head control, four could sit unassisted, two could stand with support, and two could walk independently to a toy. Overall, 260 treatment-emergent adverse events were reported in 13 patients; 259 were deemed unrelated and one likely unrelated to the MR-compatible cannula. No treatment-emergent adverse events led to study withdrawal and no deaths occurred. This study provides further evidence of the favorable pharmacodynamic, efficacy, and safety profile of eladocagene exuparvovec in children with AADC deficiency; intraputaminal administration using an MR-compatible cannula was well tolerated. Study GT-002 (NCT04903288) provides further evidence of the favourable pharmacodynamic, efficacy and safety profile of eladocagene exuparvovec gene therapy in children with AADC deficiency over 48 weeks and demonstrates that intraputaminal administration using an MR-compatible cannula was well tolerated, allowing for real-time MRI confirmation of cannula placement and infusate coverage, and for accurate dosing to the putamen.

The serotonin receptor 7 as an emerging target to restore altered neuroplasticity in Angelman syndrome.

Experimental neurology2026 Jun

The serotonin receptor 7 (5-HT7R) has been indicated as a key modulator of neuronal structure and function, playing critical roles in synaptic plasticity, dendritic spine formation, and cytoskeletal remodeling. 5-HT7R activation promotes neurite outgrowth, enhances long-term potentiation (LTP), stimulates local protein synthesis at synapses, and regulates mitochondrial functions, and the mTOR pathway. These properties make the 5-HT7R a compelling candidate for therapeutic intervention in neurodevelopmental disorders characterized by synaptic dysfunctions. Angelman syndrome (AS) is a severe neurodevelopmental disorder caused by the loss of function of the maternal UBE3A gene, resulting in impairments of synaptic plasticity, dendritic spine density, protein synthesis, mitochondrial activity and mTOR signaling. Intriguingly, many of the processes altered in AS are the ones that are positively regulated by 5-HT7R activation. For instance, AS animal models exhibit reduced LTP and altered dendritic morphology and 5-HT7R stimulation enhances synaptic strength and spine formation in the brain of wild type rodents. Moreover, BDNF/TrkB function signaling is impaired and mitochondrial integrity is disrupted in AS and 5-HT7R agonists enhance the altered BDNF/TrkB signalling and restore mitochondrial dysfunctions in Rett syndrome (RTT) mice model. Interestingly, recent evidence demonstrates that pharmacological activation of 5-HT7Rs increases synaptic protein synthesis, restores LTP, enhances dendritic spine density, and improves cognitive function in an AS mouse model. These encouraging results open the way to future studies using neurons and brain organoids generated from iPSCs obtained from AS patients, which represent novel tools in preclinical research. Overall, 5-HT7R stimulation, by counteracting the molecular alterations associated with the loss of UBE3A, may represent a novel approach to restore neural function in the mature brain, leading to translational applications in AS patients, and possibly also in other synaptopathies. Clinical trial number: not applicable.
