Abstract
Six patients are described with bi-allelic DUOX2 variants and widely variable phenotypes. Patient 1 is an infant with a compressive hypothyroid goiter causing respiratory distress, which was promptly alleviated by levothyroxine (LT4). He was a compound heterozygote for DUOX2 variants, including a novel deletion of 540 base pairs. Patients 2 and 3 are siblings with the same compound heterozygous mutations of DUOX2 , yet one had overt hypothyroidism at 14 months and the other lifelong euthyroidism. Patient 4 is a compound heterozygote individual and has mild persistent congenital hypothyroidism; his sister (patient 5) only had a borderline thyrotropin elevation at newborn screening, consistent with homozygous DUOX2 variants with a mild impact on enzyme activity. Their euthyroid mother (patient 6) is a compound heterozygote for the same DUOX2 mutations as her son. Targeted exome sequencing did not reveal any relevant modifiers. It is concluded that (i) prompt LT4 replacement in infants with respiratory distress due to a hypothyroid goiter makes surgery unnecessary; and (ii) the clinical expression of DUOX2 deficiency varies widely between individuals and over time, justifying periodic reevaluation of the need for LT4 replacement.

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
