Homozygous partial genomic triplication of the parkin gene in early-onset parkinsonism

Abstract

Autosomal recessive mutations in the parkin gene are the predominant cause of familial, early-onset parkinsonism; missense mutations involving one or a few nucleotides, exonic deletions and duplications have been described. Here we report a family with two affected brothers. Direct sequencing of parkin did not detect mutations, but semi-quantitative analysis identified a novel exonic rearrangement of exons 2-4. Both patients were homozygous for unique genomic triplications of the parkin gene.
