Síndrome de ataxia espástica-epilepsia mioclônica-neuropatia de início precoce
ORPHA:313772CID-10 · G11.4OMIM 614487PCDT · SUSDOENÇA RARA

A síndrome de ataxia espástica, epilepsia mioclônica e neuropatia de início precoce é uma doença rara e hereditária (passada de pais para filhos) que causa falta de coordenação com rigidez. Ela se manifesta na infância com uma fraqueza progressiva e rigidez nas pernas, além de problemas de coordenação que pioram lentamente, incluindo dificuldade para falar, para engolir e uma perda gradual dos movimentos. Além disso, a síndrome está ligada a problemas nos nervos que afetam tanto a sensibilidade quanto os movimentos (neuropatia sensório-motora), resultando em fraqueza e perda de massa muscular nas extremidades das pernas (como pés e panturrilhas). Também causa uma forma de epilepsia que piora com o tempo, caracterizada por espasmos musculares repentinos e involuntários (mioclonias). Outros sintomas que podem aparecer incluem: problemas nos olhos (como pálpebra caída e dificuldade em mover os olhos de forma coordenada), dificuldade em controlar a precisão dos movimentos, dificuldade em fazer movimentos rápidos e repetidos, movimentos involuntários de torção ou posturas anormais (distonia) e espasmos musculares súbitos.

Spinocerebellar ataxia 28

Spinocerebellar ataxia is a clinically and genetically heterogeneous group of cerebellar disorders. Patients show progressive incoordination of gait and often poor coordination of hands, speech and eye movements, due to degeneration of the cerebellum with variable involvement of the brainstem and spinal cord. SCA28 is an autosomal dominant cerebellar ataxia (ADCA) with a slow progressive course and no evidence of sensory involvement or cognitive impairment.

Expanding the Genetic Landscape of ATXN2 Variants: Insights From a Biallelic Trinucleotide Repeat Expansion in an Acadian Family.

Neurology. Genetics2026 Feb

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.

Novel KIF5A variant in a patient with early-onset levodopa-responsive Parkinson's syndrome.

BMJ case reports2026 Feb 02

We present the case of a male in his mid-30s with a progressive complex neurological phenotype primarily characterised by levodopa-responsive parkinsonism with motor fluctuations as well as gait ataxia, peripheral neuropathy and finally also spastic paraplegia. Genetic analysis identified a novel heterozygous variant in the KIF5A gene: c.937G>A (p.Glu313Lys). This variant is genetically classified as likely pathogenic. Other pathogenic mutations in the KIF5A gene are associated with hereditary spastic paraplegia type 10, Charcot-Marie-Tooth disease type 2 and amyotrophic lateral sclerosis. We discuss the clinical, genetic and prognostic implications of this finding.

Expanding the clinical and immunological phenotypes of COPB1 deficiency.

Frontiers in immunology2026

COPB1 encodes the coatomer subunit beta protein, which is essential for brain development and intracellular protein trafficking. Homozygous mutations cause Baralle-Macken syndrome that characterized by global developmental delay, severe intellectual disability, and early-onset cataracts. Although immunodeficiency has been observed in patients with COPB1 deficiency, the immunological phenotype remains incompletely characterized. Here, we comprehensively describe the clinical features and delineate the immunological phenotype associated with COPB1 mutations. We performed detailed clinical and immunological evaluations of three female siblings with COPB1 deficiency. Flow cytometry was used to characterize lymphocyte subsets and to assess cytokine secretion following stimulation. Functional proliferation of peripheral blood mononuclear cells (PBMCs) was assessed using dye labeling, CD3/CD28 activation, and flow cytometric analysis. Three female siblings with COPB1 deficiency presented with early-onset cataracts, global developmental delay, hypotonia, and progressive spasticity leading to quadriplegia. All patients experienced recurrent infections beginning in early childhood. Immunological evaluation revealed neutropenia, T cell lymphopenia, profound reduction in switched and unswitched memory B cells, and absent specific antibody responses. All the three patients were initiated on immunoglobulin replacement therapy and antimicrobial prophylaxis. Our findings expand the clinical and immunological spectrum of COPB1 deficiency, demonstrating combined immunodeficiency with neutropenia, lymphopenia and impaired specific antibody responses. These results support the classification of COPB1 deficiency as a combined immunodeficiency with syndromic features under the IUIS classification system and emphasize the importance of comprehensive immunological evaluation and early immunoglobulin replacement therapy in patients with COPB1 mutations.

The genetics of autosomal recessive ALS: a review of the common forms and their phenotypes.

Amyotrophic lateral sclerosis &amp; frontotemporal degeneration2026 Jan 27

Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease marked by progressive degeneration of upper and lower motor neurons. Most forms of ALS associated with a suspected causal variant are inherited in an autosomal dominant manner. However, there is an important subset of autosomal recessive (AR) variants, often associated with early-onset or atypical clinical features. Advances in genetic sequencing have led to increased recognition of AR ALS. In this review, we focus on four key confirmed AR ALS-associated genes, which appear to be most common-ALS2, SPG11, OPTN, and the D90A variant of SOD1-reviewing their pathophysiology and unique clinical manifestations. We also highlight very rare AR mutations implicated in ALS, including SYNE1, ATP13A2, and FUS, and some associated with overlap syndromes or debated pathogenicity including SIGMAR1, ERLIN1, and ERLIN2. These genes are involved in an array of processes including axonal transport, endosomal trafficking, oxidative stress response, and autophagy, suggesting distinct mechanisms of motor neuron degeneration. Some forms of AR ALS more frequently present with juvenile onset and slower progression, but other genes are associated with broader phenotypic spectra. This includes overlap with hereditary spastic paraplegia (HSP) and hereditary ataxias. Understanding these AR forms of ALS may enhance diagnostic precision, improve prognostication, and may pave the way for targeted gene therapies. This review underscores the emerging significance of AR inheritance in ALS and calls for deeper investigation into its molecular and clinical dimensions.

The Age of Definitive Fusion Surgery for Early Onset Scoliosis Has Remained Constant Over the Past 2 Decades.

Journal of pediatric orthopedics2026 Jan 06

Treatment options for early-onset scoliosis (EOS) are confounded by the risks associated with intervention at a younger age. Spinal instrumentation must be considered carefully due to potentially adverse effects to the spine, chest wall, and lungs. Posterior spinal fusion before subsequent growth can also lead to the crankshaft phenomenon. With the recent increasing interest in delaying spinal fusion, we aim to determine trends in patient age selection at a single definitive (termed "one and done") fusion for EOS. We identified 791 patients from 2005 to 2022 who met the inclusion criteria (age 5 y or younger, single definitive fusion, and complete data). Patients who underwent a hemivertebrae resection with limited fusion were not included. Multiple linear regression was performed with date of fusion as the independent variable and age at definitive fusion as the dependent variable. Our regression included race and sex to control for their effects as confounders. We repeated this analysis with groups separated by scoliosis etiology and sex. Coefficients with P<0.05 were considered significant. In the entire cohort, there was no significant change in the age at definitive fusion between 2005 and 2022 (coefficient=0.042, P=0.099). The mean age at fusion was 12.1 years. Of these, 167 (21.1%) cases had congenital scoliosis, 277 (35.0%) had idiopathic scoliosis, 191 (24.1%) had neuromuscular scoliosis, and 156 (19.7%) had syndromic scoliosis. Patients with idiopathic (-0.002, P=0.962), syndromic (-0.027, P=0.671), and neuromuscular (-0.005, P=0.924) EOS showed no significant change in the age at fusion. However, children with congenital EOS (0.171, P=0.006) and females (0.082, P=0.003) demonstrated a significant increase. On the basis of our regression models, the predicted age at definitive fusion increased from 10.6 years to 12.3 years in those with congenital EOS and from 11.4 to 12.1 years in females. Over a 17-year study period, females and congenital EOS patients demonstrated significant increases in age at the time of definite fusion. There was no significant change for children with neuromuscular, idiopathic, or syndromic EOS over the same time frame. Further study is necessary to determine the nature of these disparities.
