Abstract
There is increasing evidence that people with autism spectrum disorders (ASDs) have abnormalities in the serotonergic system. For example, a functional polymorphism of the serotonin transporter gene promoter region (5HTTLPR long/short polymorphism) has been reported to confer risk for ASDs, and to affect cortical grey matter volume in young children. However, the persistence of this association later in development is unknown. Hence, we investigated whether variation in the 5HTTLPR long/short polymorphism modulates brain anatomy in older people with ASD. We related 5HTTLPR long/short polymorphism in 43 adolescents and adults with ASD to brain anatomy using structural magnetic resonance imaging and voxel-based morphometry. There were no significant associations between brain anatomy and genotype. When considered alongside evidence of a relationship between 5HTTLPR genotype and brain volume amongst children with autism, our findings raise the possibility that the relationship between 5HTTLPR polymorphism and brain anatomy in ASDs anatomy may differ as a function of age and/or ASD subdiagnosis.

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
