The Search for Genetic Clues to Determine Chronic Wasting Disease Susceptibility

As cases of chronic wasting disease (CWD) continue to rise, USDA’s Animal and Plant Health Inspection Service (APHIS) is looking to genetics for new and innovative ways to reduce the prevalence of this brain-wasting disease in farmed and wild deer and elk populations. Working in collaboration with Texas A&M University and Texas Parks and Wildlife, APHIS has identified a handful of promising regions in the white-tailed deer genome allowing the researchers to distinguish animals highly susceptible to CWD with greater than 80 percent accuracy.
