Association of a single nucleotide polymorphism in <i>CPB2</i> encoding the thrombin‐activable fibrinolysis inhibitor (TAFI) with blood pressure
Bibliographic record
Abstract
Thrombin-activable fibrinolysis inhibitor (TAFI) is a hepatically secreted zymogen, whose substrates include bradykinin. The CPB2 gene encoding TAFI is a candidate gene for blood pressure. A recently identified single nucleotide polymorphism (SNP) in the CPB2 coding region, designated as 1057C > T, results in an amino acid change at TAFI residue 325 (Ile > Thr325). We found that the genotype based on this SNP was significantly associated with blood pressure in aboriginal Canadians. Specifically, analysis of variance showed that homozygotes for CPB2 1057T had significantly lower diastolic blood pressure than subjects with other CPB2 genotypes. CPB2 genotype accounted for approximately 3% of the total variation in diastolic blood pressure. consistent with the expected magnitude of a modest genetic effect in a complex trait such as blood pressure. Although the mechanism underlying the association is unclear, the findings are of interest because TAFI may provide a link between coagulation and blood pressure regulation.

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.
