CoA synthase protein associated neurodegeneration

CoA synthase protein associated neurodegeneration (CoPAN) is a type of neurodegeneration with brain iron accumulation (NBIA).

Clinical presentation

Patients typically present with a variety of symptoms including spastic-dystonic paraparesis, Parkinsonism, cognitive impairment, obsessive-compulsive disorder.

Pathology

Coenzyme A (CoA) synthase (gene: CoASY) is a cofactor involved in enzymatic reactions. Mutations in the CoASY gene leads to brain iron accumulation.

Radiographic features

MRI and CT
