It was only the discovery of the torsinA (TOR1A) gene in 1997 (1) as the major cause for primary generalized dystonia, traditionally also called “Oppenheim’s dystonia,” that promised to shed more light on the molecular events leading to dystonic syndromes, and thus, the ultimate cause of at least a subgroup of dystonic disorders. The gene discussed is TOR1A; the disease is Dystonia.
