Alexander diseaseA rare, progressive leukoencephalopathy (OMIM:203450) of the CNS, histologically characterised by widespread accumulation of Rosenthal fibres (cytoplasmic inclusions in astrocytes) and failure of central myelination. The most common form develops in infancy, and is accompanied by megalencephaly, developmental delay, spasticity, seizures and psychomotor retardation. Patients with juvenile or adult forms experience ataxia, bulbar signs and spasticity and slower progression.
Defects in GFAP, which encodes a major intermediate filament, cause Alexander disease.
