Rapid-onset dystonia-parkinsonism (RPD) is an autosomal dominant movement disorder characterized by sudden onset of persistent dystonia and parkinsonism, generally during adolescence or early adulthood. Symptoms evolve over hours or days, and generally stabilize within a few weeks, with slow or no p

Abstract
Rapid‐onset dystonia–parkinsonism (RDP, DYT12, MIM 128235) is a rare autosomal dominant movement disorder characterized by abrupt onset of slow, dystonic movements and prominent bulbar features. Three families and 1 isolated case have been described in the literature, and linkage to markers on chromosome 19q13 have been reported. Here, we describe the clinical features in a fourth family (the second in Europe) with 4 affected members, suggesting that RDP may be misdiagnosed for years and/or may mimic other dystonic/parkinsonian syndromes. By using haplotype analysis, we show that the family is consistent with linkage to markers on chromosome 19q13. © 2004 Movement Disorder Society
