Kufor-Rakeb syndrome (KRS; PARK 9) is a rare autosomal-recessive form of juvenile-onset Parkinson’s disease (PD) caused by ATP13A2 gene mutations. The classical description of KRS is that of rapidly progressive symptoms in the form of parkinsonism, spasticity, supranuclear upgaze paresis, facial-faucial-finger minimyoclonus, visual hallucinations, oculogyric dystonic spasms, and dementia, usually noted between 12 and 16 years of age, resulting in early severe motor handicap. World-wide prevalence of KRS is unknown, with only case reports/series being published.[2, 3] We report on the first case of KRS from India, with previously unreported nonsense mutation in exon 22 ofATP13A2 gene (chr1: 17316187; G>A).
