Juvenile parkinsonism associated with heterozygous frameshift ATP13A2 gene mutation

We report a case of levodopa-responsive juvenile parkinsonism (JP) associated with a heterozygous ATP13A2 gene frameshift mutation. The clinical phenotype of our case is more severe when compared with other published reports of symptomatic heterozygous ATP13A2 mutation carriers. To our knowledge, this is the youngest reported patient with JP associated with a heterozygous ATP13A2 mutation. Our findings expand the clinical phenotypic spectrum of JP associated with heterozygous ATP13A2 mutation. (C) 2011 European Paediatric Neurology Society. Published by Elsevier Ltd.
