Alexander disease (AxD) is the only known human pathology caused by mutations in an astrocyte-specific gene, glial fibrillary acidic protein (GFAP). These mutations result in abnormal GFAP accumulations that promote seizures, motor delays and, ultimately, death. The exact contribution of increased,
Alexander disease is a neurodegenerative disorder characterized pathologically by demyelination and accumulation of eosinophilic hyaline bodies (Rosenthal fibers) within astrocytes. Demonstration of Rosenthal fibers on histological examination is considered a prerequisite for a definitive diagnosis.
Alexander disease is a rare progressive leukoencephalopathy inherited in an autosomal dominant manner. The infantile form is the most common, with onset before 2 years of age. The typical clinical signs include psychomotor retardation and regression, seizures, and megalencephaly. Juvenile and adult
Alexander disease (AxD) is a progressive neurodegenerative disease caused by a mutation in the glial fibrillary acid protein (GFAP) gene. A 4-year-old boy presented several times with hemiclonic seizures with eye deviation for a few minutes at 28 days after birth. Electroencephalogram showed
We encountered a male infant with infantile Alexander disease presenting with megalencephaly and hydrocephalus as a neonate and subtle seizures at 3 months of age. At 6 months of age, bulbar paralysis appeared. Brain magnetic resonance imaging (MRI) showed abnormal findings with white matter
Alexander disease is a rare, degenerative disorder of the central nervous system. It is characterized clinically by spasticity, seizures, dementia, loss of developmental milestones, and macrocephaly. Here we describe a 13-year-old boy with Alexander disease and severe scoliosis. The patient
OBJECTIVE
To delineate the phenotype and genotype characteristics in 12 Chinese children with Alexander disease (AD), which is helpful for the molecular diagnosis and genetic counseling in China.
METHODS
Clinical diagnosis of AD was based on MRI criteria proposed by van der Knaarp in 2001. Included
To delineate the phenotype and genotype in Chinese children with type I Alexander disease (AxD) and the parental origin of de novo glial fibrillary acidic protein (GFAP) mutations. Twenty-two children with clinically diagnosed type I AxD were followed up for 1.66-6.62 years. Allele-specific PCR was
Alexander disease is a rare neurodegenerative disorder. Its most frequent subtype, the infantile form, is characterized by an early onset and a rapid neurological deterioration during the first months of life. Since the publication of cerebral radiological criteria in 2001, the disease has often
Alexander disease is a leukoencephalopathy that usually presents during infancy with developmental delay, macrocephaly and seizures. Several sequencing analyses have identified mutations in the gene encoding glial fibrillary acidic protein (GFAP) of patients with Alexander disease. We described a
Alexander disease is a rare, sporadic leukoencephalopathy characterized by white-matter abnormalities with frontal predominance and, as a rule, clinically associated with megalencephaly, seizures, spasticity, and psychomotor deterioration. We describe a boy who was diagnosed as affected by anorexia
Glial fibrillary acidic protein (GFAP) mutation has been reported in Alexander disease. We report a 31-year-old woman suffering from Alexander disease with a V87L mutation in GFAP. She showed psychomotor regression and a history of seizures, in addition to pendular nystagmus, dysarthria, spastic
A 41-year-old woman presented with short-stepped gait from 20 years old and with repeated loss of consciousness from 21 years old. She had a deep cerebral white matter lesion on brain MRI at 34 years of age, but she did not reach a definitive diagnosis. At the age of 41, the gait disorder rapidly
Objective: To identify the clinical and genetic characteristics in 43 Chinese children diagnosed with type Ⅰ Alexander disease (AxD). Method: Forty-three type Ⅰ AxD cases identified by glial fibrillary acidic protein (GFAP) gene mutations in Peking University First Hospital from 2005 to 2016 were
