Alexander disease

Al·ex·an·der dis·ease

(al-ek-zan'dĕr), [MIM*203450] a rare, fatal degenerative disease of the central nervous system of infants, characterized by psychomotor retardation, seizures, and paralysis; megaloencephaly is associated with widespread leukodystrophic changes, especially in the frontal lobes.

Alexander disease

A 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.
Molecular pathology
Defects in GFAP, which encodes a major intermediate filament, cause Alexander disease.
