Abstract
Prion gene (PRNP) mutations are associated with diverse disease phenotypes, including familiar Creutzfeldt-Jakob Disease (CJD), Gerstmann-Sträussler-Scheinker disease (GSS), and fatal familial insomnia (FFI). Interestingly, PRNP mutations have been reported in patients diagnosed with Alzheimer's disease, dementia with Lewy bodies, Parkinson's disease, and frontotemporal dementia. In this review, we describe prion mutations in Asian countries, including Republic of Republic of Korea, China, and Japan. Clinical phenotypes and imaging data related to these mutations have also been introduced in detail. Several prion mutations are specific to Asians and have rarely been reported in countries outside Asia. For example, PRNP V180I and M232R, which are rare in other countries, are frequently detected in Republic of Korea and Japan. PRNP T188K is common in China, and E200K is significantly more common among Libyan Jews in Israel. The A117V mutation has not been detected in any Asian population, although it is commonly reported among European GSS patients. In addition, V210I or octapeptide insertion is common among European CJD patients, but relatively rare among Asian patients. The reason for these differences may be geographical or ethical isolation. In terms of clinical phenotypes, V180I, P102L, and E200K present diverse clinical symptoms with disease duration, which could be due to other genetic and environmental influences. For example, rs189305274 in the ACO1 gene may be associated with neuroprotective effects in cases of V180I mutation, leading to longer disease survival. Additional neuroprotective variants may be possible in cases featuring the E200K mutation, such as KLKB1, KARS, NRXN2, LAMA3, or CYP4X1. E219K has been suggested to modify the disease course in cases featuring the P102L mutation, as it may result in the absence of prion protein-positive plaques in tissue stained with Congo red. However, these studies analyzed only a few patients and may be too preliminary. The findings need to be verified in studies with larger sample sizes or in other populations. It would be interesting to probe additional genetic factors that cause disease progression or act as neuroprotective factors. Further studies are needed on genetic modifiers working with prions and alterations from mutations.

Prion protein codon 129 polymorphism in mild cognitive impairment and dementia: the Rotterdam Study. Brain Commun 2020; 2:fcaa030. [PMID: 32954288 PMCID: PMC7425338 DOI: 10.1093/braincomms/fcaa030] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2019] [Revised: 02/12/2020] [Accepted: 02/17/2020] [Indexed: 12/31/2022] Open
Abstract
Creutzfeldt–Jakob disease is a rare, fatal, neurodegenerative disease caused by the accumulation of abnormally folded prion proteins. The common polymorphism at codon 129 (methionine/valine) in the prion protein (PRNP) gene is the most important determinant of genetic susceptibility. Homozygotes of either allele have a higher risk of sporadic Creutzfeldt–Jakob disease. Various studies suggest that this polymorphism is also involved in other forms of dementia. We studied the association between the codon 129 polymorphism of the PRNP gene and mild cognitive impairment in 3605 participants from the Rotterdam Study using logistic regression analyses. Subsequently, we studied the association between this polymorphism and incident dementia, including Alzheimer’s disease, in 11 070 participants using Cox proportional hazard models. Analyses were adjusted for age and sex. We found the prevalence of mild cognitive impairment to be higher for carriers of the methionine/methionine genotype (odds ratio, 1.40; 95% confidence interval, 1.11–1.78; P = 0.005) as well as for carriers of the valine/valine genotype (odds ratio, 1.37; 95% confidence interval, 0.96–1.97; P = 0.08). The codon 129 polymorphism was not associated with the risk of incident dementia or Alzheimer’s disease. In conclusion, we found a statistically significant higher prevalence of mild cognitive impairment in carriers of the methionine/methionine genotype in the codon 129 polymorphism of the PRNP gene within this population-based study. No associations were found between the codon 129 polymorphism and dementia or Alzheimer’s disease in the general population.

Abstract
The prion protein (PRNP) gene is associated with prion diseases, whereas variants of the PRNP gene may also explain some cases of Alzheimer disease (AD) and frontotemporal dementia (FTD) in Caucasian populations. To determine the prevalence of the PRNP gene in patients with AD and FTD in China, we screened all exons of the PRNP gene in a cohort of 683 cases (606 AD and 77 FTD) in the Chinese Han population and we detected a novel missense mutation p.S17G in a late-onset AD (LOAD) patient. Furthermore, we analyzed the PRNP M/V polymorphism at codon 129, which was previously reported as a risk factor. However, there were no significant differences in genotype and allele frequency either in AD (OR = 0.75[0.378-1.49], P = 0.492), or FTD patients (OR = 2.046[0.265-15.783], P = 0.707). To our knowledge, this is the first study to reveal a correlation between the PRNP gene and Chinese AD and FTD patients in a large cohort. This study reports a novel p.S17G mutation in a clinically diagnosed LOAD patient, suggesting that the PRNP mutation is present in Chinese AD patients, whereas, M129V polymorphism is not a risk factor for AD or FTD in the Chinese Han population.

Abstract
The polymorphism at codon 129 of the prion protein gene (PRNP) is a major risk factor for Creutzfeldt-Jakob disease (CJD). Several authors reported neuropathological and clinical overlapping between CJD and Alzheimer's disease (AD), with a few association studies generating conflicting results. To investigate the distribution of this polymorphism in AD, we selected 58 patients with probable AD and 73 controls from a Brazilian population. There was no association between the PRNP polymorphism at codon 129 and AD. Our meta-analysis (performed using Alzgene; http://www.alzgene.org) along with previous studies conducted in Brazil demonstrated a negative association.

Abstract
Interaction of prion protein and amyloid-b oligomers has been demonstrated recently. Homozygosity at prion protein gene (PRNP) codon 129 is associated with higher risk for Creutzfeldt-Jakob disease. This polymorphism has been addressed as a possible risk factor in Alzheimer disease (AD).ObjectiveTo describe the association between codon 129 polymorphisms and AD.MethodsWe investigated the association of codon 129 polymorphism of PRNP in 99 AD patients and 111 controls, and the association between this polymorphism and cognitive performance. Other polymorphisms of PRNP and additive effect of apolipoprotein E gene (ApoE) were evaluated.ResultsCodon 129 genotype distribution in AD 45.5% methionine (MM), 42.2% methionine valine (MV), 12.1% valine (VV); and 39.6% MM, 50.5% MV, 9.9% VV among controls (p>0.05). There were no differences of cognitive performance concerning codon 129. Stratification according to ApoE genotype did not reveal difference between groups.ConclusionCodon 129 polymorphism is not a risk factor for AD in Brazilian patients.

Abstract
BACKGROUND The M/V polymorphism in the PRNP gene has been extensively examined for the association to the risk of Alzheimer disease (AD); however, results from different studies have been inconsistent. The aim of this study is to evaluate the association between the M/V polymorphism in the PRNP gene and the risk of AD. METHODS A meta-analysis was carried out to analyze the association between the M/V polymorphism in the PRNP gene and the risk of AD. RESULTS A total of 4228 cases and 4324 controls in 16 case-control studies were included in the meta-analysis. The results indicated that the variant V allele carriers (VV+MV) had a 13% decreased risk of AD, when compared with the homozygote MM (VV+MV vs. MM: OR=0.87, 95% CI=0.79-0.96, P=0.004). In the subgroup analysis by ethnicity, significant decreased risks of AD were found in the Caucasian V allele carriers (OR=0.85, 95% CI=0.77-0.94, P=0.002), but not in Asian V allele carriers (OR=1.11, 95% CI=0.78-1.57, P=0.57). In the subgroup analysis by age of onset, significant decreased risks of AD were associated with V allele carriers in late-onset Alzheimer disease (OR=0.76, 95% CI=0.62-0.93, P=0.007) but not in early-onset Alzheimer disease (OR=0.86, 95% CI=0.70-1.06, P=0.17). CONCLUSIONS Our results suggest that the M/V polymorphism in the PRNP gene contributes to the susceptibility of Alzheimer disease.

Abstract
Although prion diseases are most commonly modeled using the laboratory mouse, the diversity of prion strains, behavioral testing and neuropathological assessments hamper our collective understanding of mouse models of prion disease. Here we compared several commonly used murine strains of prions in C57BL/6J female mice in a detailed home cage behavior detection system and a systematic study of pathological markers and neurotransmitter systems. We observed that mice inoculated with RML or 139A prions develop a severe hyperactivity phenotype in the home cage. A detailed assessment of pathology markers, such as microglial marker IBA1, astroglial marker GFAP and degeneration staining indicate early striatal pathology in mice inoculated with RML or 139A but not in those inoculated with 22L prions. An assessment of neuromodulatory systems including serotonin, dopamine, noradrenalin and acetylcholine showed surprisingly little decline in neuronal cell bodies or their innervations of regions controlling locomotor behavior, except for a small decrease in dopaminergic innervations of the dorsal striatum. These results implicate the dorsal striatum in mediating the major behavioral phenotype of 139A and RML prions. Further, they suggest that measurements of activity may be a sensitive manner in which to diagnose murine prion disease. With respect to neuropathology, our results indicate that pathological stains as opposed to neurotransmitter markers are much more informative and sensitive as markers of prion disease in mouse models.

Abstract
The genetic epidemiology of sporadic Alzheimer's disease (SAD) remains a very active area of research,making it one of the most prolifically published areas in medicine and biology. Numerous putative candidate genes have been proposed. However, with the exception of apolipoprotein E (APOE), the only confirmed genetic risk factor for SAD, all the other data appear to be not consistent. Nevertheless, the genetic risk for SAD attributable to the APOE gene in the general population is 20-0%, providing a strong evidence for the existence of additional genetic risk factors. The first part of the present article was dedicated to non-APOE genetics of SAD, reviewing chromosomes-by-chromosomes the available data concerning the major candidate genes. The second part of this article focused on some recently discovered aspects of the APOE polymorphism and their implications for SAD. An attempt to identify the future directions for non-APOE genetic research in SAD was also discussed.

Abstract
BACKGROUND Polymorphisms of the prion protein gene (PRNP) at codons 129 and 219 play an important role in the susceptibility to Creutzfeldt-Jakob disease (CJD), and might be associated with other neurodegenerative disorders. Several recent reports indicate that polymorphisms outside the coding region of PRNP modulate the expression of prion protein and are associated with sporadic CJD, although other studies failed to show an association. These reports involved the polymorphism PRNP 1368 which is located upstream from PRNP exon 1. In a case-controlled protocol, we assessed the possible association between the PRNP 1368 polymorphism and either Alzheimer's disease (AD) or vascular dementia (VaD). METHODS To investigate whether the PRNP 1368 polymorphism is associated with the occurrence of AD or VaD in the Korean population, we compared the genotype, allele, and haplotype frequencies of the PRNP 1368 polymorphism in 152 AD patients and 192 VaD patients with frequencies in 268 healthy Koreans. RESULTS AND CONCLUSION Significant differences in genotype, allele and haplotype frequencies of PRNP 1368 polymorphism were not observed between AD and normal controls. There were no significant differences in the genotype and allele frequencies of the PRNP 1368 polymorphism between Korean VaD patients and normal controls. However, in the haplotype analysis, haplotype Ht5 was significantly over-represented in Korean VaD patients. This was the first genetic association study of a polymorphism outside the coding region of PRNP in relation to AD and VaD.

Abstract
BACKGROUND Human prion protein gene (PRNP) is considered a critical and fundamental gene in determining the incidence of human prion diseases. Codons 129 and 219 play an important role in the susceptibility to sporadic Creutzfeldt-Jakob disease (CJD). An association between sporadic CJD and the polymorphism (PRNP 1368) in an upstream of PRNP exon 1 has been reported in the British and German populations, but study in the Dutch population has failed to confirm an association. PURPOSE To investigate whether the PRNP 1368 polymorphism is associated with sporadic CJD in the Korean population. METHODS We compared the genotype and allele frequencies of PRNP 1368 polymorphism in 171 sporadic CJD patients with those in 212 healthy Koreans. RESULT AND CONCLUSION A significant difference of genotype and allele frequencies at PRNP 1368 was found between the normal Korean population and various European populations. In contrast to the results in the British and German populations, our study does not show a significant difference in genotype (P = 0.2763) and allele (P = 0.3750) frequencies of PRNP 1368 between sporadic CJD and normal controls.
