All infected FVB/N mice (19/19) showed the same characteristic pattern of PrP deposition and diglycosylated PrP dominant PrPSc type (Fig 4B) as seen after transmission of frontal cortex or parietal cortex from the 129MV vCJD patient to the same mice. This evidence concerns the gene PRNP and variant Creutzfeldt-Jakob disease.
