Age of onset and severity of idiopathic torsion dystonia (ITD) were studied in 100 British families containing 107 index cases and 79 secondary cases. Analysis of variance of these clinical features did not suggest that ITD is genetically heterogenous, and they were similar in Jewish and non-Jewish
