Is it true that Creutzfeldt-Jakob disease is caused by the misfolding of the human protein PrP?
Yes. Creutzfeldt-Jakob disease is a fatal neurodegenerative disorder fundamentally caused by the misfolding of the human cellular prion protein into a pathogenic, self-propagating isoform.
Verdict: SUPPORTED · 6 sources for, 0 against · Last checked
The analysis
The retrieved literature consistently and overwhelmingly supports the claim that Creutzfeldt-Jakob disease and other prion diseases are caused by the misfolding of the prion protein (PrP).
