An intronic expansion (AAGGG)exp in the RFC1 gene has recently been shown to cause recessively inherited cerebellar ataxia, neuropathy, and vestibular areflexia syndrome and, furthermore, a few patients with ataxia and parkinsonism have been reported. We investigated 569 Finnish patients with medicated parkinsonism for RFC1 and found biallelic (AAGGG)exp in three non-consanguineous patients with clinically confirmed Parkinson’s disease without ataxia suggesting that RFC1-related disorders include Parkinson’s disease as well.
