An intronic expansion (AAGGG) 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) in three non-consanguineous patients with clinically confirmed Parkinson's disease without ataxia suggesting that RFC1-related disorders include Parkinson's disease as well.
最近研究表明，RFC1基因中的内含子扩张（AAGGG）会导致隐性遗传性小脑共济失调、神经病变和前庭反射消失综合征，此外，还报道了一些患有共济失调和帕金森症的患者。我们对569名患有药物性帕金森症的芬兰患者进行了RFC1基因检测，在3名非近亲的临床确诊帕金森病患者中发现了双等位基因（AAGGG），这些患者无共济失调症状，这表明RFC1相关疾病也包括帕金森病。
