Mutation screening of X‐chromosomal neuroligin genes: No mutations in 196 autism probands
Bibliographic record
Abstract
Autism, a childhood neuropsychiatric disorder with a strong genetic component, is currently the focus of considerable attention within the field of human genetics as well many other medical-related disciplines. A recent study has implicated two X-chromosomal neuroligin genes, NLGN3 and NLGN4, as having an etiological role in autism, having identified a frameshift mutation in one gene and a substitution mutation in the other, segregating in multiplex autism spectrum families (Jamain et al. [2003: Nat Genet 34:27-29]). The function of neuroligin as a trigger for synapse formation would suggest that such mutations would likely result in some form of pathological manifestation. Our own study, screening a larger sample of 196 autism probands, failed to identify any mutations that would affect the coding regions of these genes. Our findings suggest that mutations in these two genes are infrequent in autism.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
