Taken together our current in vivo and in vitro studies indicate that sporadic VPSPr and familial CJDV180I share a unique glycoform-selective prion formation pathway in which the conversion of diglycosylated and mono181 PrPC to PrPSc is inhibited probably by. This disease is rapidly progressive and always fatal. Sporadic forms of prion disease include sporadic Creutzfeldt-Jakob disease sCJD sporadic.

People with sporadic prion disease have no family history of the disease and no identified mutation in the PRNP gene. Human prion diseases are rare neurodegenerative diseases that have become the subject of public and scientific interest because of concerns about interspecies transmission and the unusual biological properties of the causal agents.
