Abstract
Background: The NKX2-5 gene encodes a transcription factor that plays a role in atrioventricular nodal and myocardial development. Pathogenic variants of NKX2-5 are associated with congenital heart disease and sudden cardiac death. The missense variant in this case is one of the more common ones in Northern Europe and has high penetrance in familial cases. To our knowledge, this is the youngest person who died due to this variant. Case summary: This was a healthy, asymptomatic 14-year-old male with well-managed mild congenital dilated cardiomyopathy who died unexpectedly in his home. Postmortem examination revealed the NKX2-5 pathogenic missense variant, p.Phe145Leu, as the only explicable cause of death. Discussion: We propose that immediate family members of those who die suddenly due to NKX2-5 disease undergo genetic counseling and longitudinal screening to include this gene, as pathogenic variants in the NKX2-5 gene may manifest in a time-dependent manner.

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
