Geographic variation in the PRNP gene and its promoter, and their relationship to chronic wasting disease in North American deer.
PRNP genotypes, number of octarepeats (PHGGGWGQ) and indels in the PRNP promoter can influence the progression of prion disease in mammals. We found no relationship between presence of promoter indels in white-tailed deer and mule deer from Nebraska and CWD presence. White-tailed deer with the 95 H allele and G20D mule deer were more likely to be CWD-free, but unlike other studies white-tailed deer with the 96S allele(s) were equally likely to be CWD-free. We provide the first information on PRNP genotypes and indels in the promoter for Key deer (all homozygous 96SS) and Coues deer (lacked 95 H and 96S alleles, but possessed a uniquely high frequency of 103 T). All deer surveyed were homozygous for three tandem octarepeats.
期刊介绍:
Prion is the first international peer-reviewed open access journal to focus exclusively on protein folding and misfolding, protein assembly disorders, protein-based and structural inheritance. The goal is to foster communication and rapid exchange of information through timely publication of important results using traditional as well as electronic formats. The overriding criteria for publication in Prion are originality, scientific merit and general interest.
