For instance, among early-onset dystonia syndromes, the detection of isolated generalised dystonia will first raise the suspicion of TOR1A- or THAP1-related dystonia [18,19], whereas the co-occurrence of myoclonus will suggest mutations in SGCE, ANO3, or KCTD17 [20,21,22]. The gene discussed is TOR1A; the disease is Dystonia.
