Abstract

We studied POLG1 in 140 UK patients with idiopathic Parkinson disease (PD) and 279 Italian patients with PD and compared them to a UK control group (n = 207) and an Italian control group (n = 285). Our observations do not support a role for common POLG1 genetic variants in PD and indicate that dominant POLG1 mutations are a rare cause of parkinsonism in the general population.
