Abstract: | Background Alexander disease (ALX) is a rare neurological disorder characterized by white matter degeneration and cytoplasmic inclusions
in astrocytes called Rosenthal fibers, labeled by antibodies against glial fibrillary acidic protein (GFAP). Three subtypes
are distinguished according to age at onset: infantile (under age 2), juvenile (age 2 to 12) and adult (over age 12). Following
the identification of heterozygous mutations in GFAP that cause this disease, cases of adult-onset ALX have been increasingly reported. |
