Alexander disease

A rare disorder of the central nervous system. The most common form affects infants and young children, and is characterized by progressive failure of central myelination, usually leading to death within the first decade. Infants with Alexander disease develop a leukodystrophy with macrocephaly, seizures, and psychomotor retardation. Patients with juvenile or adult forms typically experience ataxia, bulbar signs and spasticity, and a more slowly progressive course. Histologically, Alexander disease is characterized by Rosenthal fibers, homogeneous eosinophilic inclusions in astrocytes.

Progressive gait and motor deficits in a rat model of Alexander disease.

Behavioural brain research2026 Mar 21

Alexander disease is a leukodystrophy caused by gain-of-function mutations in the gene for Glial Fibrillary Acidic Protein (GFAP) which result in accumulation and aggregation of GFAP protein, astrocyte dysfunction, and ultimately developmental delay, failure to thrive, and intellectual and motor impairment. A Gfap+/R237H rat model, designed to mimic the common R239H human variant, meets normal milestones during early postnatal development, but declines dramatically as the rats mature. At severe stages of disease, Gfap+/R237H rats exhibit cognitive and motor deficits and increased mortality. Here we provide a more detailed analysis of the Gfap+/R237H rat with respect to onset of motor impairments and increasing loss of function. We show that Gfap+/R237H rats develop abnormal open field activity as they mature but stabilize with age, and that motor deficits are apparent as early as 4 weeks of age, as demonstrated by poor rotarod performance. We use automated gait analysis to further characterize subtle differences at this early age and demonstrate the progression and persistence of impairment at late stages of disease. In addition, we find evidence for changes in cerebellar size, suggesting a potential neuroanatomical correlate to the observed deficits. The rat model provides a novel system in which to investigate aspects of impaired motor function and central nervous system pathology that are directly relevant to the human disease.

Alexander Disease: A Literature Review for Clinicians.

Journal of child neurology2026 Mar 16

Alexander disease (ALEXD; MIM 203450) is a rare leukodystrophy caused by dominant mutations in the GFAP (Glial Fibrillary Acidic Protein) gene, which encodes a key structural protein of astrocytes. First described in 1949, ALEXD is now recognized as a clinically heterogeneous disorder with a broad phenotypic spectrum spanning neonatal, infantile, juvenile, and adult-onset forms. Clinical manifestations vary according to age at onset and disease subtype, ranging from early developmental impairment and progressive neurologic decline to later-onset presentations dominated by bulbar dysfunction, ataxia, and spinal cord involvement. Diagnosis can be challenging because of phenotypic overlap with other neurologic conditions; however, characteristic magnetic resonance imaging patterns combined with molecular confirmation of GFAP mutations are central to diagnosis. To date, more than 100 GFAP mutations have been reported, although robust genotype-phenotype correlations remain elusive. Pathogenic GFAP variants lead to astrocyte dysfunction through protein aggregation, oxidative stress, and cytoskeletal disorganization, resulting in Rosenthal fiber formation. Elevated GFAP levels in cerebrospinal fluid have emerged as a potential biomarker, though their clinical utility remains under investigation. Current management is supportive, but emerging gene-targeted approaches, including antisense oligonucleotides such as zilganersen and AAV-mediated gene silencing strategies, offer promising therapeutic prospects. This review provides an updated overview of the clinical, radiologic, genetic, and molecular features of ALEXD, emphasizing its spectrum of phenotypes across age groups and ongoing efforts toward improved diagnosis and targeted treatment.

Natural History and Prognostic Factors in Pediatric Alexander Disease: A Cohort Study.

Pediatric neurology2026 Mar

This study aims to clarify the natural course of Alexander disease and explore genotype‒phenotype correlations and prognostic factors. This single-center, bidirectional cohort study included patients genetically confirmed with Alexander disease, aged between 0 and 18 years. Survival curve analysis was conducted to evaluate the acquisition and loss of motor/cognitive skills to clarify the natural course of the disease. Statistical methods such as survival curve analysis and Cox regression analysis were used to analyze genotype‒phenotype correlations and prognostic factors. A total of 81 patients were included. A total of 27 types of gene variants were found among all the children, with 40.7% (11/27) in the 1A domain. At the last follow-up, 12.3% (10/81) of the patients had died. Survival curve analysis for the ability of "walking without support," "sitting down without support," "holding head upright," "understanding and following simple instructions," and "saying simple words" were lost at an average age of 15.2 ± 1.2 years, 17.3 ± 1.4 years, 17.2 ± 1.3 years, 18.8 ± 14.6 years, and 18.2 ± 1.3 years, respectively. Prognostic factor analysis via Cox single-factor and multifactor regression analysis found that patients with variants of R239 had a greater incidence of poor outcome than other variants did (hazard ratio: 2.597 [95% confidence interval: 1.052, 6.409], P = 0.038). The overall prognosis of Alexander disease is poor, with an average age at death of 18.6 ± 1.4 years and a high incidence of epilepsy (81.5%). Variants of R239 are potential prognostic factors for poor outcome.

Mutant glial fibrillary acidic protein reduces the capacity for glutamate uptake in hippocampal astrocytes.

Neuroscience letters2026 Mar 15

Astrocytes preserve synaptic function and maintain excitatory-inhibitory balance by regulating neurotransmitter homeostasis, notably through the clearance of glutamate from the extracellular space. This process is essential for preventing excitotoxicity in the central nervous system. Mutations in glial fibrillary acidic protein (GFAP) are associated with astrocytic dysfunction, leading to neurological symptoms, e.g., seizures. Although such mutations are implicated in neurological disorders including Alexander disease, their direct impact on the astrocytic uptake of synaptically released glutamate has not been demonstrated. Here, we assessed glutamate uptake in hippocampal astrocytes of mice expressing mutant GFAP using whole-cell recordings of transporter-mediated currents in acute hippocampal slices. Glutamate release into the synaptic cleft varied according to the intensity of afferent fiber stimulation, but transporter current amplitudes did not differ significantly between mutant and control mice under baseline conditions. In contrast, when adenosine A1 receptors were blocked to relieve the tonic inhibition of glutamate release, transporter currents were significantly smaller in mutant mice than in controls at high stimulation intensities. These findings indicate that astrocytes expressing mutant GFAP exhibit impaired glutamate uptake capacity, which may be insufficient to prevent excitotoxicity or seizures under conditions of excessive glutamate release.

Characterization of Clinical Phenotype to Glial Fibrillary Acidic Protein Concentrations in Alexander Disease.

Annals of clinical and translational neurology2026 Jan 09

To determine the concentration of glial fibrillary acidic protein (GFAP) in cerebrospinal fluid (CSF) and plasma in Alexander disease (AxD) and whether GFAP levels are predictive of disease phenotypes. CSF and plasma were collected (longitudinally when available) from AxD participants and non-AxD controls. The concentration of GFAP was compared between groups using Wilcoxon rank sum test. The Kruskal-Wallis test was used to compare GFAP concentrations across multiple groups (clinical phenotype or common genetic variants occurring at p.Arg79, p.Arg88, p.Arg239). GFAP concentrations were significantly elevated at baseline in both AxD CSF (N = 44) compared to controls (N = 46, p < 0.0001) and AxD plasma (N = 96) compared to other leukodystrophy plasma controls (N = 67, p < 0.0001). CSF and plasma GFAP concentrations differed between AxD cerebral, intermediate, and bulbospinal phenotypes (Kruskal-Wallis test, CSF: p = 0.0235, plasma: p < 0.0001). The median GFAP change/year among patients sampled < 8 years of age at baseline was an increase of 91,100 [pg/mL]/year (IQR 136,050) in CSF and 2850 [pg/mL]/year (IQR 9500) in plasma compared to patients > 8 years whose medians decreased over time (-41,000 [pg/mL]/year [IQR 90,300], CSF; -843 [pg/mL]/year [IQR 3900], plasma). The fold change in GFAP from first to last sampling were significantly different before and after 8 years at baseline (Wilcoxon rank sum test, CSF: p = 0.0232, plasma: p = 0.0002). A significant association was not detected between GFAP variant and GFAP levels. GFAP concentrations are higher in the cerebral phenotype and increase over time in young children. These data can be used to formulate biomarker qualification and context-of-use in AxD.
