Chronic wasting disease (CWD) is caused by prions, infectious proteinaceous particles, PrPCWD. We sequenced the PRNP gene of 2,899 white-tailed deer (WTD) from Illinois and southern Wisconsin, finding 38 haplotypes. Haplotypes A, B, D, E, G and 9 others encoded Q95G96S100N103A123Q226, designated 'PrP variant A.' Haplotype C and 4 other haplotypes encoded PrP 'variant C' (Q95S96S100N103A123Q226). Haplotype F and two other haplotypes encoded PrP 'variant F' (H95G96S100N103A123Q226). The

Relative to PrP variant A, CWD susceptibility was lower in deer with PrP variant C (OR = 0.26, p OR = 0.10, p OR = 0.25, p OR = 0.07, p PRNP polymorphisms may be a useful tool in CWD management.
