Abstract
We defined the molecular basis and correlated the hematological phenotypes with the globin genotypes in 52 patients with Hb H disease and 29 patients with AEBart's disease of northeast Thailand. Among the former group, the most prevalent molecular defect was found to be the interaction of alpha-thalassemia 1 (SEA type) with the Hb Constant Spring (Hb CS; 35 of 52 patients), followed by the deletion of three alpha-globin genes with the SEA type alpha-thalassemia 1 and the 3.7- or 4.2-kb deletion of alpha-thalassemia 2 (14 of 52 patients) and the interaction of the SEA alpha-thalassemia 1 with the Hb Paksé which was found in the remaining 3 patients. Among the 29 patients of the latter group, in 18 disease was caused by interactions of Hb E heterozygotes with the SEA alpha-thalassemia 1 and Hb CS. Interaction of Hb E heterozygotes with a deletional form of Hb H disease was detected in 7 patients and the Hb Paksé AEBart's disease was found in another 3 patients. A remaining patient with an unusually severe form of AEBart's disease with a lower Hb E level and observable Hb H was associated with a hitherto undescribed condition, the interaction of Hb E heterozygote with alpha-thalassemia 1 and an alpha2 codon 30 (GAG) deletion. Hematological characterization of the patients demonstrated that although disease in most of them was associated with thalassemia intermedia phenotypes, it was apparent that association with the nondeletional form of alpha-thalassemia 2 produced a more severe phenotype than that of the deletional one. Therefore, alpha-globin gene analysis of Hb H and AEBart's disease patients would be useful for predicting the clinical outcome and improving genetic counseling.

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
