Three New α-Thalassemia Point Mutations Ascertained Through Newborn Screening
Bibliographic record
Abstract
We report three new alpha-thalassemia (thal) point mutations detected during newborn screening for hemoglobinopathies. The first mutation is a single nucleotide deletion (-A) that abolishes the translation initiation codon of the alpha2-globin gene, detected in a newborn of Hmong ethnicity who carried the Southeast Asian alpha(0)-thal deletion (alpha(T)alpha/- -(SEA)). The second mutation, a frameshift caused by a single nucleotide deletion in exon 2 of the alpha1-globin gene [codon 78 (-C)], was detected in a Black/Chinese newborn who also carried the Southeast Asian alpha0-thal deletion (alphaalpha(T)/- -(SEA)). The third mutation was a frameshift in exon 3 of the alpha2-globin gene, codons 113/114 (-C). This mutation was detected in a newborn who carried the 3.7 kb alpha(+)-thal deletion (alpha(T)alpha/-alpha(3.7)).

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
