Abstract
The enzyme 3 beta-hydroxysteroid dehydrogenase/delta 5-delta 4-isomerase (3 beta-HSD) catalyses an essential step in the biosynthesis of all steroid hormones. Consequently, classical 3 beta-HSD deficiency is responsible for a severe form of congenital adrenal hyperplasia. The HSD3B1 and HSD3B2 genes encoding the types I and II 3 beta-HSD isoenzymes, respectively, have been previously assigned by in situ hybridization to the chromosome 1p13.1 region. To determine the physical distance between these two genes, NotI and SacII digests of genomic DNA were resolved by pulse-field gel electrophoresis and hybridized with type I and type II 3 beta-HSD cDNAs used as probes. The detection of a single band under low stringency conditions indicates that HSD3B1 and HSD3B2 are located within an approximately 0.29 megabase SacII DNA fragment. We constructed a high resolution genetic map of the region flanking the polymorphic HSD3B1 and HSD3B2 genes including ten Généthon markers and the two NIH/CEPH markers AMY2B and D1Z5. The HSD3B1A and HSD3B2A markers were mapped relative to other reference markers through eight CEPH reference families. The order of polymorphic genes and markers is: pter-[AMY2B-D1S239]-D1S457-D1S502-D1S250-+ ++D1S252-[HSD3B1A -HSD3B2A-D1S514]-[D1Z5-D1S442]-D1S305-D 1S303-D1S484-qter. The D1S514 marker was thus closely linked to HSD3B1A (theta < 0.001; lod = 14.13) and HSD3B2 (theta = 0.008; lod = 35.36). The HSD3B loci are located 1-2 cM of the centromeric marker D1Z5.

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
