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
"Eye of the tiger sign" on T2 MRI (like PKAN) associated with bilateral basal ganglia calcifications.
