Molecular assay reagents intended to identify mutations in the prion protein (PRNP) gene, located at chromosome 20pter-p12, which encodes for the prion protein that has been implicated in various types of transmissible neurodegenerative spongiform encephalopathies. This genetic mutation has been identified in patients with genetically transmitted prion diseases such as familial Creutzfeldt-Jakob disease (fCJD), Gerstmann-Straussler-Scheinker (GSS) syndrome, and fatal familial insomnia (FFI).
