Abstract
Kleefstra syndrome is a rare genetic disorder caused by haploinsufficiency of the euchromatic histone lysine methyltransferase 1 (EHMT1) gene. It is characterized by a variety of dysmorphic features, comorbid medical issues, and developmental delays/intellectual disability. Neuropsychiatric symptoms may also occur, including autistic features and psychosis, and are often accompanied by functional regression. However, the phenomenology of psychotic symptoms in this syndrome has not been well described in the literature. As such, in this brief report, we review the literature with respect to the occurrence of psychosis in Kleefstra syndrome and describe the symptom profile of a 35-year-old affected male with an intellectual disability, autism spectrum disorder, and schizophrenia (in association with manic features). This is the first report of psychotic symptoms fully remitting in response to zuclopenthixol therapy in an individual with Kleefstra syndrome. This case is also unique as it demonstrates that functional regression does not necessarily coincide with the development of schizophrenia-like presentations in affected individuals.

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
