Definition:

Neuroferritinopathy is a rare autosomal dominant disease caused by mutations in the ferritin light chain (FTL) gene leading to abnormal excessive iron accumulation in the brain, predominantly in the basal ganglia. Clinically, the disease presents as a chorea and dystonia. Clinical presentation may also include extrapyramidal and pyramidal tract signs as well as cerebellar ataxia, dysautonomia, cognitive decline, and psychiatric symptoms.
