Abstract
BACKGROUND: Analbuminemia is a rare autosomal recessive disorder in which individuals have little or no circulating albumin, usually the most abundant plasma protein. We describe a new mutation associated with analbuminemia. METHODS: We studied four apparently unrelated patients who had congenital analbuminemia: two of Amerindian and two of Turkish origin. The 14 exons and the flanking intron sequences of the albumin gene were amplified by PCR and screened for mutations by single-strand conformational polymorphism and heteroduplex analysis. The mutated DNA fragments were sequenced directly. RESULTS: In all four cases, analbuminemia was caused by the same mutation, an AT deletion at nucleotides 2430-2431, the 91st and 92nd bases of exon 3. This novel defect, named Kayseri, produces a frameshift leading to a premature stop two codons downstream. The predicted translation product would consist of 54 amino acid residues. CONCLUSIONS: The AT deletion at nucleotides 2430-2431 is a novel mutation associated with analbuminemia.

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
