Hipercinesia refere-se a um aumento na atividade muscular que pode resultar em movimentos excessivos, sejam anormais, normais ou combinados. A hipercinesia é um estado de inquietação excessiva que é apresentado em uma grande variedade de distúrbios que afetam a capacidade de controlar o movimento motor, como a doença de Huntington. É o oposto da hipocinesia, que se refere à diminuição do movimento corporal, como comumente manifestado na doença de Parkinson.

Emerging disease-modifying therapies for Angelman syndrome: A comprehensive review for pediatric neurologists.
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.
PRPS1 (p.V42L) Mutation in Arts Syndrome Induces Aberrant Neural Stem Cell Development and Neuronal Senescence-Like Phenotype: Rescue by Nicotinamide Mononucleotide Supplementation.
Arts syndrome is a rare X-linked recessive neurodevelopmental disorder arising from pathogenic variants in PRPS1, which encodes phosphoribosyl pyrophosphate synthetase 1-an enzyme essential for de novo nucleotide biosynthesis. Affected individuals typically exhibit sensorineural hearing loss, intellectual disability, cerebellar ataxia, and recurrent infections. However, despite the severity of these clinical manifestations, therapeutic interventions remain limited, largely due to an incomplete understanding of the cellular pathophysiology underlying the disorder. In this study, we generated patient-specific induced pluripotent stem cells harboring the PRPS1 p.V42L variant and differentiated them into neural stem cells (NSCs) and neurons to elucidate disease mechanisms and explore potential therapeutic strategies. Patient-derived NSCs demonstrated significantly reduced proliferative capacity, aberrant nuclear morphology, and increased neuronal senescence, while mitochondrial integrity and function were largely preserved. Neurons differentiated from these NSCs exhibited impaired neurite outgrowth and reduced branching complexity, indicative of disrupted neurodevelopmental processes. Notably, supplementation with nicotinamide mononucleotide, a precursor of nicotinamide adenine dinucleotide (NAD+), partially ameliorated defects in NSC proliferation, nuclear architecture, and neuronal morphology. Collectively, these findings delineate key cellular mechanisms underlying PRPS1-associated neurodevelopmental pathology and identify NAD+ metabolic augmentation as a promising therapeutic avenue for Arts syndrome and related PRPS1-mediated disorders.
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.
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.
Expanding the Genetic Landscape of ATXN2 Variants: Insights From a Biallelic Trinucleotide Repeat Expansion in an Acadian Family.
Spinocerebellar ataxias are a diverse group of autosomal dominant cerebellar ataxias. SCA2 is a complex ataxia with various extracerebellar symptoms, including parkinsonism, dystonia, hyporeflexia, and cognitive impairment. ATXN2 is a modulator of neurologic disease: Expansions of at least 37 CAG (glutamine) repeats are pathogenic for SCA2, while expansions in the intermediate range (30-32) convey risk for the development of neurodegenerative disorders including Parkinson disease and amyotrophic lateral sclerosis. Homozygous variants are exceedingly rare. This study describes a novel ATXN2 presentation identified in an Acadian family from New Brunswick, Canada: a CAG repeat expansion within the fully penetrant range of SCA2, asymptomatic in the heterozygous state and resulting in a neurodegenerative disorder in homozygous patients. Three individuals, 2 siblings and their cousin, were investigated for a neurodegenerative disorder with overlapping phenotypes. The affected individuals and their 5 immediate family members underwent whole-genome sequencing analyzed by ExpansionHunter, repeat-primed PCR and Sanger sequencing. Sequencing revealed a homozygous 39/39 CAG repeat expansion with 4 CAA interruptions in ATXN2 across all 3 affected individuals. After experiencing childhood intellectual or learning difficulties, the patients developed a pyramidal syndrome with spastic gait and a major neurocognitive disorder characterized by prominent frontal signs during their late twenties. Within a decade, all patients completely lost their autonomy. Shared phenotypic features included ataxia, spasticity, aphasia, dysphagia, myoclonus, atypical parkinsonism, incontinence, diffuse cortical atrophy with frontal predominance, and cerebellar atrophy. The same 39 CAG repeat allele with 4 CAA interruptions was identified in heterozygous state in 4 asymptomatic parents (age 65+) and 1 sibling in their thirties. Three carriers consented to further investigation with a neurologic examination, neuropsychological assessment, and cerebral MRI. Clinical and radiologic signs of disease were absent, despite the carriers' ages and their heterozygous expansion in the fully penetrant range of SCA2. This study describes a novel ATXN2 expansion within the classic pathogenic range for SCA2 that manifests as an early-onset neurodegenerative disorder in the homozygous state, while being asymptomatic into late adulthood in the heterozygous state.
Biallelic Novel SKOR2 Variants in Individuals With Cerebellar Hypoplasia and Intellectual Disability, Expanding the Phenotypic Spectrum of Valence-Farazi Cerebellar Ataxia Syndrome.
The embryonic development of the cerebellum is orchestrated through a dynamic process that governs the interplay of Purkinje and granule cell populations. SKOR2 (Fussel 18) is a transcriptional co-repressor that increases SHH (sonic hedgehog) expression which is a potent signal for granule cell proliferation and integration into the complex neuronal network that underlies cerebellar function and development. Complete loss of Skor2 function in a murine model has been shown to result in cerebellar hypoplasia due to severe disruption of the cerebellar vermis. Through GeneMatcher we identified eight individuals from five unrelated families with compound heterozygous or homozygous loss of function, splice site and missense variants in SKOR2 associated with a phenotypic spectrum of cerebellar hypoplasia, microcephaly, ataxia, developmental delays and intellectual disability. Variants identified in SKOR2 included homozygous c.1877delC; p.Pro626Glnfsx156 in the first individual, homozygous c.2752 + 1G>T in the second and third individuals, compound heterozygous c.757T>G p.C253G, c.949T>A p.S317T in the fourth individual, homozygous c.421_424del (p.Asp141Ilefs*118) in the fifth, sixth, and seventh individuals, and a homozygous c.1169C>A; p.Ser390* in the eighth individual. The eight individuals had various degrees of developmental and speech delays, as well as cerebellar hypoplasia identified in some of them. In silico analysis supported pathogenicity of most of SKOR2 variants, except for case 4, and their impact on protein function. Recently, SKOR2 is reported to be associated with Valence-Farazi Cerebellar Ataxia Syndrome (OMIM # 621386) (Skor2-OMIM-OMIM.ORG). This study expands the phenotypic spectrum for this newly described condition. Additional studies in affected individuals will be needed to refine the phenotypic spectrum and identify genotype-phenotype correlations.
