The X-linked dystonia-parkinsonism syndrome (XDP): clinical and molecular genetic analysis.

Author information

Institute of Neuropathology, Ludwig-Maximilians-University of Munich, Germany.


Dystonia and parkinsonism are two major representatives of movement disorders. The X-linked dystonia-parkinsonism syndrome (XDP) serves as a model system for the study of both dystonia and parkinsonism since both symptom complexes occur together and are inherited as Mendelian traits with very high penetrance. XDP, which is endemic to the Philippine island of Panay, originated by a single mutation ("genetic founder effect"), thus assuring homogeneity of the disorder at the molecular level. The disease locus, DYT3, has been assigned to the proximal long arm (Xq12-21.1) of the human X chromosome. A strategy is described to isolate this gene by positional cloning. The rationale of this strategy, the major methods involved and technical terms are explained.
