Adult-onset generalized dystonia due to a mutation in the neuroferritinopathy gene.

Neuroferritinopathy is a recently recognized autosomal dominant disorder that results in abnormal aggregates of iron and ferritin in the brain due to a mutation in the ferritin light chain gene on chromosome 19q13.3. We present the clinical details of a patient with adult-onset generalized dystonia associated with this mutation. Neuroferritinopathy appears to be a rare disorder; hence, there is a need to report new cases to further our understanding of the clinical phenotype, diagnostic challenges, the course of the condition and imaging characteristics.
