Early-onset Parkinson's disease: a novel deletion comprising the DJ-1 and TNFRSF9 genes

Abstract

Patients with mutations in DJ-1 have early-onset Parkinson's disease and slow progression. Here we describe a Turkish family with a large deletion in the neighboring genes DJ-1 (del exons 1-5) and TNFRSF9 (del exons 1-6), raising the question if TNFRSF9 is a possible disease modifier.
