Phenotypic differences in the brains and limbs of mutant mice caused by differences of <i>Gli3</i> gene expression levels
Bibliographic record
Abstract
ABSTRACT The genetic polydactyly/arhinencephaly mouse, Pdn/Pdn , exhibits severe polydactyly both in the fore‐and hindlimbs, agenesis of the olfactory bulbs, corpus callosum, anterior commissure, and hydrocephalus. A candidate gene for the Pdn mouse has been speculated to be Gli3 , because Pdn has been considered to be an allele of Xt whose responsible gene has been clarified to be Gli3. Recently, it has been cleared that retro‐transposons are inserted into nitron 3, upstream of zinc finger domain, of the Gli3 gene in the Pdn mouse, resulting to the severe suppression of Gli3 gene expression in Pdn/Pdn embryos. Meanwhile, Xt J /Xt J mice exhibit more severe polydactyly than that of Pdn/Pdn. Arhinencephaly and microholoprosencephaly including agenesis of the olfactory bulbs, corpus callosum, anterior commissure, hippocampal commissure, habenular commissure, and posterior commissure, and moreover, the cerebral cortical plates and hippocampus are not formed in the Xt J /Xt J mice. The Xt J /Xt J mouse has a large deletion in Gli3 structural gene and shows null expression. From these corroborations, we speculated that the differences in the Gli3 gene expression levels resulted in the phenotypic differences between the Pdn/Pdn and Xt J /Xt J mice.

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.
