摘要：

We report on an Italian kindred with adult-onset primary torsion dystonia (PTD). A detailed clinical examination of the six definitely affected family members revealed a mild, purely focal phenotype. The disease involved only one body part (eyes, neck, or arm). PTD in this family was not linked to the known disease loci (DYT1, DYT6, DYT7, and DYT13), and the 3-bp deletion in the DYT1 gene was also excluded. These findings support genetic heterogeneity of PTD and indicate that a novel unassigned gene is responsible for focal dystonia in this family. (C) 2002 Movement Disorder Society.
