Analysis of <i>PDE6D</i> and <i>PDE6G</i> genes for generalised progressive retinal atrophy (gPRA) mutations in dogs
Bibliographic record
Abstract
The δ and γ subunits of the cGMP-phosphodiesterase ( PDE6D , PDE6G ) genes were screened in order to identify mutations causing generalised progressive retinal atrophy (gPRA) in dogs. In the PDE6D gene, single nucleotide polymorphisms (SNP) were observed in exon 4, in introns 2 and 3 and in the 3' untranslated region (UTR) of different dog breeds. In the coding region of the PDE6G gene, exclusively healthy Labrador Retrievers showed an A → G transition in exon 4 without amino acid exchange. SNP were also observed in introns 1 and 2 in different dog breeds. The different SNP were used as intragenic markers to investigate the involvement of both genes in gPRA. The informative substitutions allowed us to exclude mutations in the PDE6D and PDE6G genes as causing retinal degeneration in 15 of the 22 dog breeds with presumed autosomal recessively transmitted (ar) gPRA.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
