Abstract
ABSTRACT Background ATP1A3 mutations cause a wide clinical spectrum, and are one of the “commoner rare diseases”. Methods Case series of four patients with ATP1A3 mutations. Results The patients displayed characteristic episodes of dystonic arm posturing, involving a dystonic, flexed arm held in front of the body or close to the body, but with the hand raised upwards. Other attacks manifested with arm extension, either beside the body or reaching upwards. Dystonic posturing occurred paroxysmally, with no neurological signs between attacks, or combined with other signs like chorea, ataxia, and hypotonia. Conclusions While previous diagnostic criteria have not included paroxysmal or episodic dystonia, recent expert consensus has proposed to include alternating or paroxysmal dystonia as major feature calling for ATP1A3 genetic testing. Attacks of marked arm flexion posturing, either paroxysmal or as episodic exacerbation of mild pre‐existent dystonia, are a characteristic clue to ATP1A3 ‐related disease.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
