Gαs Transcripts Are Biallelically Expressed in the Human Kidney Cortex: Implications for Pseudohypoparathyroidism Type 1b
Bibliographic record
Abstract
Pseudohypoparathyroid type 1b patients are characterized by renal resistance to PTH in the absence of Albright's hereditary osteodystrophy or other endocrine abnormalities. Kindred studies have suggested that the cause of this resistance is a specific decrease in Galphas activity in renal proximal tubules due to paternal imprinting of Galphas. To test this, allelic expression of Galphas was analyzed in human fetal kidney cortex samples by RT-PCR assays. The results showed that, in contrast to the parent-specific expression of exon 1A and XLalphas (paternal) or NESP (maternal) mRNAs, Galphas transcripts are biallelically expressed in human kidney cortex. These data implicate abnormal imprinting of alternative regions within the GNAS1 locus as a more likely cause of pseudohypoparathyroid type 1b.

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.
