Spastic ataxia 8, autosomal recessive, with hypomyelinating leukodystrophy
An autosomal recessive neurodegenerative disorder characterized by early-onset hypotonia which progresses to a pyramidal syndrome with ataxia, spasticity, hyperreflexia, weakness and loss of ambulation. Brain imaging shows cerebellar atrophy and hypomyelinating leukodystrophy.
Catalytic component of the m-AAA protease, a protease that plays a key role in proteostasis of inner mitochondrial membrane proteins, and which is essential for axonal and neuron development (PubMed:19748354, PubMed:28396416, PubMed:29932645, PubMed:30683687, PubMed:31327635, PubMed:37917749, PubMed:38157846).

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.
Polymerase that creates the 3' poly(A) tail of mitochondrial transcripts. Can use all four nucleotides, but has higher activity with ATP and UTP (in vitro). Plays a role in replication-dependent histone mRNA degradation. May be involved in the terminal uridylation of mature histone mRNAs before their degradation is initiated. Might be responsible for the creation of some UAA stop codons which are not encoded in mtDNA

Spastic ataxia 4, autosomal recessive

Cytoplasm
Spastic ataxia Charlevoix-Saguenay type
A neurodegenerative disease characterized by early-onset cerebellar ataxia, spasticity, retinal hypermyelination, pyramidal signs, and both axonal and demyelinating neuropathy with loss of sensory nerve conduction and reduced motor conduction velocities. Other features include dysarthria, distal muscle wasting, nystagmus, defect in conjugate pursuit ocular movements, retinal striation (from prominent retinal nerves) obscuring the retinal blood vessels in places, and the frequent presence of mitral valve prolapse.

Generation of eight human induced pluripotent stem cells lines from patients with Autosomal Recessive Spastic Ataxia of Charlevoix-Saguenay (ARSACS).
Autosomal Recessive Spastic Ataxia of Charlevoix-Saguenay (ARSACS) is a rare inherited neurodegenerative disorder causing progressive spasticity, ataxia and peripheral neuropathy, leading to significant motor and sensory impairments. To advance the study of ARSACS pathogenesis and therapeutic development, we generated eight induced pluripotent stem cell (iPSC) lines from patient-derived fibroblasts or peripheral blood mononuclear cells (PBMCs) using non-integrating Sendai virus-based reprogramming method and covering four different SACS gene mutations. These iPSC lines provide a powerful platform to investigate disease mechanisms, evaluate therapeutic candidates, and support the development of personalized medicine approaches for ARSACS.
Autosomal Recessive Spastic Ataxia of Charlevoix-Saguenay in Two Half-Siblings.
Autosomal recessive spastic ataxia of Charlevoix-Saguenay (ARSACS) is caused by biallelic pathogenic variants in the SACS gene. We report the clinical, radiologic and neurophysiologic features of a pair of half-siblings who presented with progressive cerebellar ataxia, peripheral neuropathy and upper motor neuron signs. After significant diagnostic delay, genetic testing revealed both harboured a shared, paternally inherited microdeletion encompassing the SACS gene, and each harboured a different single nucleotide variant in SACS, each likely maternally inherited. Recognition of the clinical and radiologic phenotype of ARSACS may facilitate early diagnosis of this disorder even in the face of uncommon inheritance patterns.
Nerve Ultrasound in Pediatric Polyneuropathies: A Systematic Review.
The diagnosis of peripheral polyneuropathy in children and the differential diagnosis among its various forms often present a challenge, also because electrodiagnostic studies can be painful and sometimes yield inconclusive results. This systematic review examines the role of nerve ultrasound (n-US) in the diagnosis and follow-up of pediatric polyneuropathies. We searched PubMed and Embase from 1975 to April 1, 2025. Included studies assessed patients aged ≤ 18 years with clinically and neurophysiologically confirmed polyneuropathy, providing pediatric-specific qualitative or quantitative n-US findings. Eighteen studies met the inclusion criteria. Six focused on acquired inflammatory polyneuropathies (three on Guillain-Barré Syndrome [GBS], three on Chronic Inflammatory Demyelinating Polyneuropathy [CIDP]), eight on Charcot-Marie-Tooth disease (CMT), two on lysosomal storage disorders, one on Autosomal Recessive Spastic Ataxia of Charlevoix-Saguenay (ARSACS), and one on mixed etiologies. Most (n = 7) were case reports. Cross-sectional area and nerve enlargement (NE) distribution were the main parameters evaluated. Marked, diffuse NE was found in demyelinating CMT and lysosomal disorders; CIDP showed diffuse and multifocal NE; GBS presented mild and proximal NE. No NE was reported in axonal CMT or ARSACS. Few studies assessed echogenicity or fascicular structure; none evaluated vascularization. n-US shows promise in differentiating demyelinating conditions such as CMT, CIDP, GBS, and certain metabolic syndromes in children. However, further age-matched control studies are needed, given that nerve growth and myelination peak between 15 and 17 years. Future research should explore n-US as an early diagnostic, screening, and follow-up tool.
Peripheral Neuropathy-Predominant Adult-Onset Autosomal Recessive Spastic Ataxia of Charlevoix-Saguenay: Novel Variant in the SACS gene.
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).
