title: An infantile-juvenile form of Alexander disease caused by a R79H mutation in GFAP.
abstract: Alexander disease is a degenerative white matter disorder due to mutations in the glial fibrillary acidic protein (GFAP) gene. It has been classified into three forms based on the age of onset and severity: an infantile, a juvenile, and an adult form. In a 6-year-old patient with a relatively mild form of Alexander disease, we detected a common R79H mutation in GFAP, previously only described in the infantile form. These results suggest the need for further studies of the genotype-phenotype correlation.
