A patient with vertebral, cognitive and behavioural abnormalities and a de novo deletion of <i>NRXN1α</i>
Bibliographic record
Abstract
The authors report a patient with mild mental retardation, autistic features, multiple vertebral malformations, and an unusual facial appearance who carries a de novo submicroscopic deletion of chromosome 2p16.3. The patient's deletion is approximately 320 kb in size and includes only the part of the NRXN1 gene that codes for the neurexin1alpha promoter and initial coding exons. The more downstream neurexin1beta promoter and the region surrounding it are intact. Neurexin1beta has been associated with autism in several recent studies, but this is the first reported patient with loss of only neurexin1alpha and not of neurexin1beta. These findings suggest that neurexin1alpha function in correct dosage is necessary for normal neurological development.

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.
