Organic Anion Transporting Polypeptide 1B1 (OATP1B1) and OATP1B3: Genetic Variability and Haplotype Analysis in White Canadians
Bibliographic record
Abstract
Organic anion transporting polypeptide 1B1 (OATP1B1) and OATP1B3 are human hepatocyte transporters that mediate the uptake of various endogenous and exogenous substances. Genetic variations in solute carrier transporter 1B1 (SLCO1B1) and SLCO1B3 genes, which encode OATP1B1 and OATP1B3 proteins, could affect the pharmacokinetics of drugs leading to interindividual differences in drug responses. The full extent of SLCO1B1 and SLCO1B3 polymorphisms in white Canadians was analyzed using DNA sequencing procedures. We identified 49 and 41 nucleotide sequence variants leading to 10 and 9 major haplotypes in SLCO1B1 and SLCO1B3 genes, respectively. We report several novel mutations within regulatory and coding regions that could affect gene transcription, translation and function. Comparison with other studies revealed that the distribution of SLCO1B1 and SLCO1B3 polymorphisms and haplotypes differs widely across populations. Data from this survey will ultimately contribute to the design of pharmacogenetic studies in the Canadian population.

How this classification was reachedexpand
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.
