Genetic Variation and Strain Dynamics in Chronic Wasting Disease
Bibliographic record
Abstract
Chronic wasting disease (CWD) is a prion disease of cervids marked by growing strain diversity and variation in host susceptibility. Central to this complexity are prion protein gene (Prnp) polymorphisms, which can modulate pathogenesis by altering the ability of cellular prion protein (PrPC) to misfold into infectious prions (PrPSc), or by promoting the emergence of novel strains. Studies in cervids and transgenic rodent models demonstrate that individual polymorphisms influence PrP stability, conversion efficiency, and the selection of PrPSc conformers, with most variants conferring partial resistance but none offering complete protection. These host–strain interactions define transmission barriers and disease phenotype. Understanding how Prnp genotypes shape CWD strain diversity is essential for predicting transmission dynamics, refining surveillance, and assessing zoonotic potential as the disease continues to expand geographically and genetically.

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.
