O que você precisa saber de cara
Ataxia espinocerebelar (AEC) é uma doença genética, progressiva e degenerativa com múltiplos tipos, cada um dos quais poderia ser considerado uma condição neurológica por si só. Estima-se que 150.000 pessoas nos Estados Unidos tenham um diagnóstico de ataxia espinocerebelar a qualquer momento. A AEC é hereditária, progressiva e degenerativa. Não há tratamento eficaz ou cura conhecidos. A AEC pode afetar qualquer pessoa de qualquer idade. A doença é causada por um gene recessivo ou dominante.

Component of the PEX1-PEX6 AAA ATPase complex, a protein dislocase complex that mediates the ATP-dependent extraction of the PEX5 receptor from peroxisomal membranes, an essential step for PEX5 recycling (PubMed:16314507, PubMed:16854980, PubMed:21362118, PubMed:29884772). Specifically recognizes PEX5 monoubiquitinated at 'Cys-11', and pulls it out of the peroxisome lumen through the PEX2-PEX10-PEX12 retrotranslocation channel (PubMed:29884772). Extraction by the PEX1-PEX6 AAA ATPase complex is

Peroxisome biogenesis disorder complementation group 4
A peroxisomal disorder arising from a failure of protein import into the peroxisomal membrane or matrix. The peroxisome biogenesis disorders (PBD group) are genetically heterogeneous with at least 14 distinct genetic groups as concluded from complementation studies. Include disorders are: Zellweger syndrome (ZWS), neonatal adrenoleukodystrophy (NALD), infantile Refsum disease (IRD), and classical rhizomelic chondrodysplasia punctata (RCDP). ZWS, NALD and IRD are distinct from RCDP and constitute a clinical continuum of overlapping phenotypes known as the Zellweger spectrum (PBD-ZSS).
Subunit of the replication factor C (RFC) complex which acts during elongation of primed DNA templates by DNA polymerases delta and epsilon, and is necessary for ATP-dependent loading of proliferating cell nuclear antigen (PCNA) onto primed DNA (PubMed:9488738). This subunit binds to the primer-template junction. Binds the PO-B transcription element as well as other GA rich DNA sequences. Can bind single- or double-stranded DNA

Cerebellar ataxia, neuropathy, and vestibular areflexia syndrome
An autosomal recessive neurologic disease characterized by imbalance, cerebellar ataxia, impaired vestibular function, and non-length-dependent sensory deficit.
Mediates the transfer of lipids between membranes at organelle contact sites (By similarity). Functions in promoting mitochondrial clearance by mitochondrial autophagy (mitophagy), also possibly by positively regulating mitochondrial fission (PubMed:29307555, PubMed:29604224). Mitophagy plays an important role in regulating cell health and mitochondrial size and homeostasis
Spinocerebellar ataxia, autosomal recessive 4
A form of spinocerebellar ataxia, a clinically and genetically heterogeneous group of cerebellar disorders due to degeneration of the cerebellum with variable involvement of the brainstem and spinal cord. SCAR4 patients manifest ataxic gait with spasticity and hyperreflexia of the lower limbs resulting in difficulty walking. The age at onset is highly variable, ranging from early childhood to adulthood.
Regulates COPI-mediated retrograde protein traffic at the interface between the Golgi apparatus and the endoplasmic reticulum (PubMed:18556652). Involved in the maintenance of the Golgi apparatus morphology (PubMed:26581903) Acts as a transcriptional activator. It binds to three different types of GC-rich DNA binding sites (box-A, -B and -C) in the beta-polymerase promoter region. It also binds to the TERT promoter region

Spinocerebellar ataxia, autosomal recessive, 21
A form of spinocerebellar ataxia, a clinically and genetically heterogeneous group of cerebellar disorders due to degeneration of the cerebellum with variable involvement of the brainstem and spinal cord. SCAR21 is characterized by cerebellar atrophy and ataxia with onset in early childhood. Patients also manifest recurrent episodes of liver failure, hepatic fibrosis and a peripheral neuropathy.
Plays a key role in the repair of DNA damage, functioning as part of both the non-homologous end-joining (NHEJ) and base excision repair (BER) pathways (PubMed:10446192, PubMed:10446193, PubMed:15385968, PubMed:20852255, PubMed:28453785). Through its two catalytic activities, PNK ensures that DNA termini are compatible with extension and ligation by either removing 3'-phosphates from, or by phosphorylating 5'-hydroxyl groups on, the ribose sugar of the DNA backbone (PubMed:10446192, PubMed:10446

Microcephaly, seizures, and developmental delay
An autosomal recessive neurodevelopmental disorder characterized by infantile-onset seizures, microcephaly, severe intellectual disability and delayed motor milestones with absent speech or only achieving a few words. Most patients also have behavioral problems with hyperactivity. Microcephaly is progressive and without neuronal migration or structural abnormalities, consistent with primary microcephaly.
Plays a role in vesicle-mediated protein trafficking to lysosomal compartments including the endocytic membrane transport and autophagic pathways. Acts as a component of the HOPS endosomal tethering complex. This complex is proposed to be involved in the Rab5-to-Rab7 endosome conversion probably implicating MON1A/B, and via binding SNAREs and SNARE complexes to mediate tethering and docking events during SNARE-mediated membrane fusion. The HOPS complex is proposed to be recruited to Rab7 on the

Atypical Clinical Course of Griscelli Syndrome Type 2 With Primarily Neurologic Presentation and Adult-Onset in a 46-Year-Old Male.
Griscelli Syndrome Type 2 (GS2) is a rare autosomal recessive disorder caused by pathogenic mutations in the RAB27A gene. Typically, it is characterized by cutaneous hypopigmentation, immunodeficiency, with or without neurological abnormalities secondary to hemophagocytic lymphohistiocytosis (HLH). Without treatment, GS2 often results in fatal outcomes within the first decade of life. Adult-onset GS2 is extremely rare, with few documented cases. We describe a 48-year-old patient with a neurological presentation: cerebellar dysarthria, ataxia, nystagmus, and muscle hypotonia in the lower limbs. Diagnostic workup included next-generation sequencing (NGS panel), clinical investigations, and segregation analysis in the family to confirm the diagnosis of GS2. Genetic testing revealed two variants in RAB27A: The likely pathogenic c.550C>T [p.(Arg184*)] and c.213G>T [p.(Gln71His)], a variant of uncertain significance. Clinical evaluation confirmed irregular hair pigmentation due to melanosome transport defect, low natural killer cell activity, cytopenia, hypertriglyceridemia, elevated serum ferritin, and brain tissue biopsy compatible with hemophagocytosis, thus cementing the clinical diagnosis of GS2. Segregation analysis confirmed the trans configuration of the variants. Based on the clinical and genetic evidence, the p.Gln71His variant was reclassified as likely pathogenic per ACMG criteria. This rare late-onset GS2 case highlights the need to consider GS2 in adult patients with atypical presentations. Early diagnosis is vital for effective intervention. Greater clinical awareness and research are needed to understand its phenotypic spectrum in adults.
Clinical, Radiological, and Genetic Profile of Patients with FA2H-Associated Neurodegeneration: Eight Cases from India and a Review of the Literature.
Autosomal recessive spastic paraplegia 35 (SPG35), also known as Fatty acid hydroxylase-associated neurodegeneration (FAHN), is a rare recessive neurodegenerative disorder with or without ataxia, dystonia, and other neurological findings. It is caused by genetic variants in FA2H, which encodes fatty acid 2-hydroxylase. To report the clinical, electrophysiological, radiological, and genetic profile of patients diagnosed with FAHN. We performed a retrospective chart review of genetically proven cases of FAHN from our database. We identified eight patients (6 females) with genetically proven FAHN. All patients presented with first-decade onset pyramidal syndrome with or without ataxia and with radiological findings of callosal atrophy, peri-ventricular white matter hyperintensity, and cerebellar atrophy. Iron accumulation was observed in four of them. Whole exome sequencing revealed seven unique variants including three missense variants (c.83G>C;p.Arg28Pro, c.130C>A;p.Pro44Thr, and c.703C>T;p.Arg235Cys), a stop-gain variant (c.379C>T;p.Arg127Ter), a frameshift deletion variant (c.536delT;p.Leu179Argfs*62), a in-frame deletion variant (c.200_202del;p.His67del) and a in-frame duplication variant (c.86_97dup;p.Arg29_Arg32dup). The variants p.Pro44Thr, p.Arg28Pro, p.Arg29_Arg32dup, and p.His67del are located in the iron-binding region, and the p.Arg235Cys in the hydroxylase domain. The other two variants, p.Arg127Ter and p.Leu179Argfs*62, predictively cause protein truncation, leading to loss of the transmembrane domain and the fatty acid hydroxylase domain, which in turn may result in disruption of fatty acid alpha-hydroxylase activity of FA2H. Our study identifies novel variants associated with FA2H in FAHN patients, highlighting their possible roles in iron binding and in the loss of the transmembrane and catalytic domains.
The Cerebellar Cognitive-Affective Syndrome Scale Reveals Consistent, Early, and Progressive Neuropsychological Deficits in Autosomal-Recessive Spastic Ataxia of Charlevoix-Saguenay: A Large International Cross-Sectional Study.
Neuropsychological deficits have been observed in patients with cerebellar damage, but never thoroughly investigated in autosomal recessive spastic ataxia of Charlevoix-Saguenay (ARSACS). The goal is the characterization of presence, severity, and profile of neuropsychological deficits in ARSACS using the cerebellar cognitive-affective syndrome (CCAS) scale. Prospective study including a discovery cohort from Saguenay/Canada (n = 31, median [inter-quartile range] age: 57 [54-62] years), and a validation cohort from Tübingen, Germany (n = 17, 35 [21-43] years) with matched controls (n = 19). All ARSACS patients failed in multiple CCAS-related subtests and exceeded cutoffs for "definite CCAS." Even the younger validation cohort failed more subtests than controls (5 [3-7] vs. 1 [1-2], P < 0.001) and had lower CCAS total scores (81 [67-86] vs. 101 [91-106], P < 0.001). Total scores worsened in the older discovery cohort (40 [25-52], P < 0.001) and correlated with age/disease duration (ρ = -0.575, P < 0.001) and ataxia severity (Scale for the Assessment and Rating of Ataxia: ρ = -0.527, P = 0.003). Neuropsychological deficits consistent with CCAS are consistent in ARSACS, present early, and progress in the disease course. © 2026 The Author(s).

MSTO1-related mitochondrial myopathy and ataxia syndrome: Case series and literature review.
We report clinical and genetic features in four patients from 3 independent families with an ultra-rare autosomal recessive myopathy associated with biallelic pathogenic or likely pathogenic variants in MSTO1. Exome or genome sequencing was used to identify genetic variants in patients with suspected hereditary myopathy who had negative results on targeted genetic panels. Age at diagnosis ranged from 13 to 30 years. All patients exhibited myopathy of variable severity. Two had congenital hypotonia and global developmental delay, while the remaining two developed muscle weakness at ages 2 and 5. Magnetic resonance imaging evidence of cerebellar atrophy was noted in Patient 3. The most common non-neurologic abnormality noted in our cases was skeletal abnormalities. MSTO1-related disease presents primarily as an early-onset myopathy, occasionally accompanied by cerebellar atrophy and skeletal abnormalities. As genome-wide sequencing is increasingly becoming a first line test for unexplained myopathy, further characterization of the phenotypic spectrum is likely.
Spinocerebellar ataxia, autosomal recessive type 23 (SCAR23) with compound TDP2 variants: clinical, molecular, and quantitative follow-up.
Spinocerebellar ataxia, autosomal recessive type 23 (SCAR23) is an ultra-rare inherited disorder caused by biallelic Loss-of-Function (LoF) variants in TDP2, a nuclear enzyme involved in DNA double-strand breaks repair. To date, only 12 cases with homozygous variants and complex neurological phenotypes have been reported. We describe a 20-year-old male presenting with cerebellar ataxia, drug-resistant epilepsy, mild intellectual disability, and recurring craniofacial traits observed in SCAR23. Additional findings included polycythemia and a pituitary hamartoma. Clinical exome sequencing (CES) identified two novel TDP2 nonsense variants. In silico and structural analyses indicated that both variants affect highly conserved residues in the catalytic domain. Longitudinal video-oculography confirmed downbeat nystagmus (DBN), while static stabilometry captured subtle postural changes over 12 months not detected by routine clinical examination, highlighting the utility of quantitative digital assessments. This case expands the genotypic spectrum of SCAR23 and highlights recurring facial traits that may aid recognition. The coexisting SHOX deletion (i.e., Leri-Weill syndrome) was considered unrelated to the neurological phenotype. Digital assessments provided objective measures of motor function over time. Our findings broaden the clinical and molecular characterization of SCAR23 and illustrate the potential of digital biomarkers for longitudinal monitoring. Despite the lack of functional validation and the inherent limitations of a single-case report, these observations provide valuable insights for future research in this ultra-rare disorder.
