  • Chronic wasting disease (CWD) is a fatal transmissible spongiform encephalopathy affecting North American cervids. I assessed the feasibility of association mapping for CWD genetic risk factors in wild white-tailed deer and mule deer using a high density microsatellite map of cattle. I chose a panel of 215 bovine microsatellite markers from three homologous deer linkage groups predicted to contain candidate genes for CWD. These markers had a low cross-species amplification rate (28 %) and showed weak linkage disequilibrium (< 1 cM). Markers near the prion protein gene (PRNP) and the neurofibromin 1 gene (NF1) were significantly associated with CWD status. Association of CWD with PRNP has been previously documented; however, this is the first time an association between the NF1 region and CWD has been reported. More accurate and powerful association mapping in these populations in the future will require much denser marker sets such as genome-wide single nucleotide polymorphism panels.
