Validation of Hagerman’s behavioral phenotype for fragile X syndrome among men with intellectual disability
Bibliographic record
Abstract
Purpose The behavioral phenotype of fragile X syndrome (FXS) and intellectual disability (ID) proposed by Hagermanet al.(2009) was primarily based on data from male children and teens. The purpose of this study was to promote a better understanding of how this condition manifests in adults. Design/methodology/approach A total of 18 men of FXS were paired with men with Down syndrome on the basis of age and level of ID. A screening checklist was created on the basis of existing scales and the Hagermanet al.(2009) behavioral phenotype and completed by care providers. Findings Five of the 12 features of the phenotype were significantly more present among men with FXS than in men with Down syndrome. Originality/value This study provides partial confirmation for Hagerman et al.’s (2009) behavioral phenotype of FXS among men with moderate ID and identified some traits that warrant further investigation.

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.
