Torsin-1A (TorA) also known as dystonia 1 protein (DYT1) is a protein that in humans is encoded by the TOR1A gene (also known as DQ2 or DYT1). [5] TorA localizes to the endoplasmic reticulum and contiguous perinuclear space , where its ATPase activity is activated by either LULL1 or LAP1 , respectively.

[3] Worldwide, it has been reported that the incidence rate of spasmodic torticollis is at least 1.2 per 100,000 person years, [ 27 ] and a prevalence rate of ...
Since it is difficult to measure extrapyramidal symptoms, rating scales are commonly used to assess the severity of movement disorders. The Simpson-Angus Scale (SAS), Barnes Akathisia Rating Scale (BARS), Abnormal Involuntary Movement Scale (AIMS), and Extrapyramidal Symptom Rating Scale (ESRS) are rating scales frequently used for such assessment and are not weighted for diagnostic purposes ...
