Definition:

Neurodegeneration due to cerebral folate transport deficiency is an autosomal recessive disorder of brain specific folate deficiency, characterized by severe developmental regression, movement disturbances, epilepsy, and leukodystrophy. Folate-receptor alpha (FOLR1) is of central importance for folate transport across the blood brain barrier via the choroid plexus. It has been reported that mutations in FOLR1 cause this disease. Folinic acid therapy can reverse the clinical symptoms and improve brain abnormalities and function.
