Abstract
Musician's dystonia is generally considered a sporadic disorder. We present three families with the index patient affected by musician's dystonia, but other forms of upper limb focal task-specific dystonia (FTSD), mainly writer's cramp, in seven relatives. Our results suggest a genetic contribution to FTSD with phenotypic variability, including musician's dystonia.
