Genetic Creutzfeldt‒Jakob disease with 5-octapeptide repeats presented as frontotemporal dementia.
The N-terminus of the PRNP gene normally contains a 5-octapeptide repeat (R1-R2-R2-R3-R4), and insertions at this locus can cause hereditary prion diseases. In the present study, we found a 5-octapeptide repeat insertion (5-OPRI) in a sibling case of frontotemporal dementia. Consistent with previous literature, 5-OPRI rarely met the diagnostic criteria for Creutzfeldt‒Jakob disease (CJD). We propose 5-OPRI as a suspected causative mutation for early-onset dementia, especially the frontotemporal type.
