Association analysis of PRNP gene region with chronic wasting disease in Rocky Mountain elk
Abstract Background Chronic wasting disease (CWD) is a transmissible spongiform encephalopathy (TSE) of cervids including white-tailed ( Odocoileus virginianus ) and mule deer ( Odocoileus hemionus ), Rocky Mountain elk ( Cervus elaphus nelsoni ), and moose ( Alces alces ). A leucine variant at posi...
