Genetic analysis of early onset Parkinson's disease (PD) has indicated that the mutation DJ-1 gene is one cause of autosomal recessive PD. Its role in the development of late onset PD and other Lewy body associated disorders such as dementia with Lewy bodies (DLB) is however unknown. We have therefore determined the influence of a common polymorphism in the DJ-1 gene that shows strong linkage disequilibrium with other DJ-1 polymorphisms, in late onset PD and DLB. No alteration in the frequency of the intron I deletion allele was seen in PD or DLB, nor were DJ-1 genotypes altered by disease. Stratification of the cases according to the apolipoprotein E epsilon4 allele additionally failed to show any significant association. The DJ-1 gene does not appear to be a significant risk factor for late onset Lewy body disease in this population. (C) 2003 Elsevier Ireland Ltd. All rights reserved.
