Creutzfeldt-Jakob disease (CJD), also known as corticostriate spinal degeneration, subacute spongiform encephalopathy or infectious spongiform encephalopathy, is a type of degenerative disease of the central nervous system caused by prion protein (PrP) infection, which is the most common type of human PrP disease.
Creutzfeldt-Jakob disease (CJD) is a fatal neurodegenerative disorder that, according to the most well accepted hypothesis (1), is caused by replicating, transmissible, abnormal forms of a host-encoded prion protein (prions).
Creutzfeldt-Jakob disease (CJD) is a rapidly progressive, fatal degenerative encephalopathy caused by a pathologically altered form of the prion protein (PrP).
Prion protein (PrP) gene encodes cellular PrP (PrPC), a glycosylphosphatidylinositol (GPI)-anchored cell membrane protein indispensable for infections of prion, which causes Creutzfeldt-Jakob disease (CJD) in humans, bovine spongiform encephalopathy (BSE) in cattle, and scrapie in sheep.
A broadening spectrum of human prion diseases has now been identified including novel entities such as Fatal Familial Insomnia and variants of CJD and GSS characterised by specific abnormalities in the human prion protein (PrP) gene on chromosome 20.
A case of Creutzfeldt-Jakob disease (CJD) with a rare mutation of the prion protein (PrP) gene (PRNP) at codon 208 (R208H), while the codon 129 was a methionine homozygous genotype is reported.
A disease-associated mutation in the PRNP gene was identified in nine (13.4%) definite and probable cases of CJD, a reliable estimate of the incidence of PRNP-related inherited CJD based on a prospective epidemiological series.
A group of 43 patients from seven families affected by Creutzfeldt-Jakob disease (CJD) with the codon 178Asn mutation of the PRNP amyloid precursor gene is compared to a group of 211 patients with the sporadic form of the disease.
A major question remains as to whether self-propagating structural differences in PrP(Sc) might account for the clinicopathological diversity evident in Creutzfeldt-Jakob disease and whether different prion protein types underlie the existence of different strains of causative agent.
A novel phenotype of familial Creutzfeldt-Jakob disease (CJD) with mutated codon 200 of the prion protein gene (PRNP) coupled with the valine codon 129 (E200K-129V haplotype) has two features never observed in subjects carrying the pathogenic mutation coupled with the methionine codon 129 (E200K-129M haplotype): (1) plaque-like prion protein (PrP) deposits in the cerebellum and (2) type 2 protease-resistant prion protein (PrP(res)).
A novel point mutation resulting in a glutamate-to-glycine substitution in PRNP at codon 200, E200G with codon 129 MV polymorphism (cis valine) and type 2 PrPSc was identified in a patient with a prolonged disease course leading to pathology-proven Jakob-Creutzfeldt disease.
A patient with Creutzfeldt-Jakob disease (CJD) with prion protein (PrP) gene codon 180 mutation (CJD 180) experienced cognitive decline over the 1.5-year period before her death.
A patient with a heterozygous variant of Creutzfeldt-Jakob disease (CJD) with a methionine/valine genotype at codon 129 of the prion protein gene was recently reported.
