Metyrosine in Psychosis Associated with 22q11.2 Deletion Syndrome: Case Report
Bibliographic record
Abstract
This report describes the use of metyrosine (Demser) in an adolescent male with psychosis associated with the 22q11.2 deletion syndrome (velocardiofacial syndrome; VCFS), diagnosed by fluorescence in situ hybridization (FISH). He presented with multiple features of 22q11.2 deletion syndrome, including ventricular septal defect, palatal abnormalities, speech and motor delays, attention deficits, mood lability, and psychosis. After a failed trial of an atypical antipsychotic to address the psychosis, metyrosine was initiated, with significant reduction of psychotic symptoms and mood lability. Metyrosine treatment allowed this youth to live at home and to attend school, after months of recurrent psychiatric hospitalizations. The successful treatment of metyrosine for psychosis associated with VCFS represents a first in psychiatry, where a known biochemical abnormality in a psychiatric disorder was corrected by a treatment that targets the biochemical pathway, leading to reduction of psychiatric symptoms and improvement of functioning.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
