Ethnic origin determines the impact of genetic variants in dopamine receptor gene () concerning essential hypertension
Bibliographic record
Abstract
The dopamine receptor type 1 (DRD1) has been implicated in the development of hypertension in humans as well as in animal models of spontaneous hypertension. We screened the entire coding and promoter region of the human DRD1 receptor for polymorphisms to analyze their association with hypertension. The allele frequencies of two common single-nucleotide polymorphisms, A-48G and G-94A were determined in 493 hypertensive patients and 209 normotensive controls. Allele frequencies did not differ for both polymorphisms between the two groups (-48 G-allele in hypertension = 0.37; -48 G-allele in normotension = 0.36; -94 A-allele in hypertension = 0.14; -94 A-allele in normotension = 0.10). Our findings in these Caucasian patients are in contrast to a recent Japanese study that revealed a significant association of the -48 G-allele with hypertension. Thus, racial differences may play an important role concerning the association of variants in the dopamine receptor type 1 gene with essential hypertension.

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.
