Kufor Rakeb syndrome (KRS), also known as Parkinson disease 9 (PARK9), is an autosomal recessive disorder characterized by subacute, juvenile onset, levodopa responsive parkinsonism, pyramidal signs, dementia, and a supranuclear gaze palsy. It has been reported that brain MRI revealed generalized atrophy and putaminal and caudate iron accumulation bilaterally. KRS is due to ATP13A2 gene mutations.
