Abstract
MAGEL2 is one of the five genes inactivated in Prader-Willi Syndrome, a neurodevelopmental chromosome microdeletion disorder modified by genomic imprinting. By early childhood, individuals with Prader-Willi Syndrome exhibit hypothalamic dysfunction, including hyperphagia, and become obese in the absence of behavioral intervention. Murine Magel2 is highly expressed in the hypothalamus during development. We screened the MAGEL2 open reading frame for mutations in genomic DNA samples from hyperphagic but non-dysmorphic individuals with severe childhood-onset obesity. Although no mutations likely to affect gene function were identified, we identified three variant alleles. We conclude that severe childhood-onset obesity is not commonly caused by MAGEL2 mutations.

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
