The <i>P2X7</i> Receptor Gene A1513C Polymorphism Does Not Contribute to Risk of Familial or Sporadic Chronic Lymphocytic Leukemia
Bibliographic record
Abstract
The P2X7 receptor, a plasma membrane ATP-gated ion channel that plays a role in lymphocyte apoptosis, has been suggested to be involved in the development of chronic lymphocytic leukemia (CLL). P2X7 is polymorphic with 1513A and 1513C alleles encoding fully active and nonfunctional proteins, respectively. We evaluated the significance of the P2X7-A1513C polymorphism on CLL risk by genotyping 424 patients and 428 healthy controls. To empower detection of an association, we included in our analysis 106 familial cases. Allele frequencies were identical in cases and controls irrespective of whether cases were familial or sporadic (frequency of the C allele was 0.17 and 0.17, respectively). The odds ratio of CLL associated with the C allele was 1.03 (95% confidence interval: 0.80-1.31). A meta-analysis of this study and five other smaller published studies provides no evidence of relationship between this P2X7 polymorphism and risk of CLL (odds ratio = 0.99, 95% confidence interval: 0.74-1.32).

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.
