HOMOZYGOSITY FOR Hb E-SASKATOON [β22(B4)Glu → Lys] IN A TURKISH PATIENT
Bibliographic record
Abstract
A 30-year-old female who is homozygous for a Hb E-like abnormal hemoglobin and her immediate relatives were studied. Clinical examination of the proband revealed no abnormality. Routine hematological analysis showed that her hemoglobin level was 12 g/dL, MCV 82 fL, MCH 28 pg, RDW 15%. DNA sequence analysis indicated the presence of a G-->A substitution at codon 22 corresponding to an abnormal hemoglobin, namely Hb E-Saskatoon [beta22(B4)Glu-->Lys (GAA-->AAA)]. Absence of any abnormalities in clinical and routine hematological investigations of the homozygous patient indicated that the phenotypical expression of the Hb E-Saskatoon is very mild. Using a reverse transcription-polymerase chain reaction technique, the alpha/beta and betaX/betaA-mRNA (X = Hb E-Saskatoon) ratios were determined. Normal alpha/beta and betaX/betaA-mRNA ratios were found in the homozygous patient and in all heterozygotes, indicating that the respective mutation did not alter the stability of the mRNA. FokI restriction enzyme analysis of the polymerase chain reaction products obtained from the genomic DNA and/or beta-globin mRNA made it possible for rapid diagnosis of Hb E-Saskatoon, and for its differentiation from Hb E [beta26(B8)Glu-->Lys (GAG-->AAG)]. Analysis of the restriction fragment length polymorphism (RFLP) in the beta-globin gene complex of the index patient and of another unrelated family with a compound heterozygosity for Hb E-Saskatoon and beta-thalassemia revealed that the Hb E-Saskatoon mutation shared a common allele.

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.
