Kufor-Rakeb syndrome (KRS; 606693), a form of autosomal recessive hereditary parkinsonism with dementia, shows juvenile onset. The role of heterozygous ATP13A2 variants in patients with early-onset Parkinson disease is unclear and controversial. Autosomal recessive spastic paraplegia-78 is an adult-onset neurodegenerative disorder characterized predominantly by spasticity and muscle weakness of the lower limbs, resulting in gait difficulties and loss of ambulation in some patients. Affected individuals also have cerebellar signs, such as dysarthria, oculomotor disturbances, and limb and gait ataxia; brain imaging shows cerebellar atrophy. Some patients may have mild cognitive impairment or frank dementia. The phenotype is highly variable. >3 cases
