A Genetic Key to CWD Management?

“They found that some regions of Illinois had somewhat higher proportions of genetically protected deer. This genetic advantage does not ensure that a deer is entirely resistant to CWD. Still, the two types of protective DNA sequences could elicit a high level of protection, suggesting that specific areas may see a lower prevalence of CWD in the population due to this genetic advantage.”

Differences in genetic vulnerability to CWD have been studied in multiple deer populations, such as the endangered Florida Key deer (Odocoileus virginianus clavium) and the threatened Columbian white-tailed deer (Odocoileus virginianus leucurus). Perrin-Stowe and collaborators (2020) found that “Key deer may be less genetically susceptible to CWD” when compared to Columbian white-tailed deer and other mainland white-tailed deer populations.

CHAMPAIGN, IL – When talking about infectious diseases, are there advantages or disadvantages associated with our genes? And how does this translate to prion diseases? In this article, the authors describe how by examining the Prion protein gen, researchers have been able to identify protective DNA sequences, with potential genetic advantage to CWD in some populations of Illinois white-tailed deer.
