Molecular Screening of the 11β‐HSD1 Gene in Men Characterized by the Metabolic Syndrome
Bibliographic record
Abstract
Adipose tissue type 1 11beta-hydroxysteroid dehydrogenase (11beta-HSD1), which generates hormonally active cortisol from inactive cortisone, has been shown to play a central role in adipocyte differentiation and abdominal obesity-related metabolic complications. The objective was to investigate whether genetic variations in the human 11beta-HSD1 gene are associated with the metabolic syndrome among French-Canadian men. We sequenced all exons, the exon-intron splicing boundaries, and 5' and 3' regions of the human 11beta-HSD1 gene in 36 men with the metabolic syndrome, as defined by the National Cholesterol Education Program-Adult Treatment Panel III, and two controls. Three intronic sequence variants were identified: two single-nucleotide polymorphisms in intron 3 (g.4478T>G) and intron 4 (g.10733G>C) and one insertion in intron 3 (g.4437-4438insA). The relative allele frequency was 19.6%, 22.1%, and 19.6% for the g.4478G, g.10733C, and g.4438insA alleles, respectively. One single-nucleotide polymorphism was identified in exon 6 (c.744G>C or G248G). The frequency of the c.744C allele was only 0.46% in a sample of 217 men. Variants were not associated with components of the metabolic syndrome except for plasma apolipoprotein B levels. In conclusion, molecular screening of the 11beta-HSD1 gene did not reveal any sequence variations that can significantly contribute to the etiology of the metabolic syndrome among French-Canadians.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
