PRKN and Parkinson disease: A woman with a 45-year history of slowly progressive parkinsonism with no motor complications.<h4>Discussion</h4>Due to the variability of phenotypes of Parkin mutations, testing should also be warranted in patients with atypical tremor syndromes or axonal polyneuropathy when more common causes have been ruled out.<h4>Highlights</h4>We report three patients with extremely atypical parkin mutation phenotypes: an atypical tremor syndrome, an axonal motor autonomic neuropathy, and a remarkably slowly progressive parkinsonism.
