Nurr1 mutational screen in Parkinson's disease.

We performed sequence analysis of all the exons and exon-intron boundaries in familial and young-onset Parkinson's disease (PD) in an Asian cohort. None of the patients carried any pathogenic mutations in the Nurr1 gene. We demonstrated a 5 to 10% prevalence of the intron 7 +33 C-->T variant among Malay and Indian PD and healthy controls, suggesting that this variant, which was previously described only in 1 Chinese patient, was not a silent mutation but a common polymorphic variant in some ethnic races. 2004 Movement Disorder Society.
