Abstract excerpt
A gene (DYT1) for idiopathic torsion dystonia maps to chromosome 9q34 in Ashkenazi Jewish families with early onset of symptoms. Further, there is linkage disequilibrium between DYT1 and a particular haplotype of alleles at 9q34 loci in this population. This implies that a large proportion of early-onset idiopathic torsion dystonia in Ashkenazi Jews is due to a founder mutation in DYT1. To characterize the...
