An interstitial deletion of the long arm of chromosome 21 in a case of a first episode of psychosis
Bibliographic record
Abstract
OBJECTIVE: Case of an interstitial deletion of the long arm of chromosome 21 presenting with first episode of psychosis. METHOD: A case report. RESULTS: A 16-year-high school student of Somalian origin presented with a first episode of psychosis, mild mental retardation and dysmorphic features. Chromosome analysis revealed an interstitial deletion in the long arm of chromosome 21, described as 46, XX del (21) (q21q22.1). CONCLUSION: First episode of psychosis occurred in combination with neurobiological vulnerability and a complex genetic inheritance. The occurrence of psychosis in our case may be attributable to genes located within the region 21q21q22.1. The possibility that other loci exist on chromosome 21, which predispose to schizophrenia has to be considered. Identification of susceptibility genes will greatly facilitate investigation of factors that contribute to the disease process and may lead to early intervention and prevention.

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.
