A Common Variant of the PAX2 Gene Is Associated with Reduced Newborn Kidney Size
Bibliographic record
Abstract
Congenital nephron number ranges widely in the human population. Suboptimal nephron number may be associated with increased risk for essential hypertension and susceptibility to renal injury, but the factors that set nephron number during kidney development are unknown. In renal-coloboma syndrome, renal hypoplasia and reduced nephron number are due to heterozygous mutations of the PAX2 gene. This study tested for an association between a common haplotype of the PAX2 gene and subtle renal hypoplasia in normal newborns. A PAX2 haplotype was identified to occur in 18.5% of the newborn cohort, which was significantly associated with a 10% reduction in newborn kidney volume adjusted for body surface area. This haplotype was also associated with reduced allele-specific PAX2 mRNA level in a human renal cell carcinoma cell line. Subtle renal hypoplasia in normal newborns may be partially due to a common variant of the PAX2 gene that reduces mRNA expression during kidney development.

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.
