There were no differences in the distribution of PART between cases stratified according to PRNP codon 129 genotype (PART+: MM 25.5% vs MV 18.3% vs VV 23.4%, p = 0.480), PrPSc type (PART+: type 1 26.1% vs type 1 + 2 25.7% vs type 2 18.9%, p = 0.322), CJD histotype (PART+: MM1 25.5% vs VV2 23.0% vs MV2K 13.2%, p = 0.232) and prion strain (PART+: M1 25.5% vs V2 19.2%, p = 0.122). Here, PRNP is linked to Creutzfeldt Jacob disease.
