Abstract

The DYT1 gene responsible for early-onset, idiopathic torsion dystonia (ITD) in the Ashkenazi Jewish population, as well as in one large non-Jewish family, has been mapped to chromosome 9q32-34. Using (GT)n and RFLP markers in this region, we have identified obligate recombination events in some of these Jewish families, which further delineate the area containing the DYT1 gene to a 6-cM region bounded by loci AK1 and ASS. In 52 unrelated, affected Ashkenazi Jewish individuals, we have found highly significant linkage disequilibrium between a particular extended haplotype at the ABL-ASS loci and the DYT1 gene. The 4/A12 haplotype for ABL-ASS is present on 69% of the disease-bearing chromosomes among affected Jewish individuals and on only 1% of control Jewish chromosomes (χ2 = 91.07, P
