Abstract
BACKGROUND: Anorexia nervosa is a complex neuropsychiatric disorder presenting with life-threatening low body weight, and a persistent fear of gaining weight. To date, no whole exome sequencing was performed in male individuals with anorexia nervosa. AIM AND METHODS: Here, we performed an exome analysis in two independent families with male individuals with anorexia nervosa and found variants in the Neuronatin (NNAT) gene in both probands. To confirm our data, we carried out the screening of the NNAT gene in a cohort of 8 male and 144 female individuals with anorexia nervosa. RESULTS: Exome sequencing revealed a nonsense variant p.Trp33* in NNAT in one patient and a rare variant in the 5'UTR region of NNAT in the other patient. Screening of the NNAT gene in a cohort of 8 male and 144 female individuals with anorexia nervosa allowed to identify 11 other NNAT variants showing that 40.00% and 6.25% of male and female anorexia nervosa individuals carried a NNAT variant, respectively. Moreover, two novel missense variants were identified in female anorexia nervosa patients. CONCLUSION: Our data suggest that NNAT variants and NNAT expression changes may be associated with susceptibility to eating disorders such as anorexia nervosa.

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
