Using this system, we found a new mutation of the PrP gene in a patient with pathologically confirmed Creutzfeldt-Jakob disease and a negative family history for dementia.
(1991) reported an association between homozygosity in a polymorphic site at codon 129 of the PrP gene, coding for either valine or methionine, with a tendency to acquire the sporadic or iatrogenic forms of CJD, as well as with disease age of appearance in the genetic type.
Fatal familial insomnia (FFI) and a subtype of familial Creutzfeldt-Jakob disease (CJD), two clinically and pathologically distinct diseases, are linked to the same mutation at codon 178 (Asn178) of the prion protein gene.
