multiple sclerosis (ms) is a chronic inflammatory disorder of the central nervous system, with a complex etiology that includes a strong genetic component. the chromosome 19q 13 region surrounding the apolipoprotein e (apoe) gene has shown consistent evidence of involvement in ms. in a cross-sectional study, to show the apoe genotype and allele frequency in the ms population of iran in comparis...

Alzheimer disease (AD) is the most frequent cause of dementia in Western countries. Putative genetic risk factors for AD are polymorphisms in the apolipoprotein E (APOE) gene and in the low-density lipoprotein receptor-related protein (LRP) gene. Our objective was to investigate the role of the APOE coding region polymorphisms epsilon 2, epsilon 3, and epsilon 4 and APOE promoter variants A/T a...

The aim of the present study was to investigate the association of APOE, MTHFR and ACE polymorphisms with stroke in the Zambian population. We analyzed 41 stroke patients and 116 control subjects all of Zambian origin for associations between the genotype of the APOE, MTHFR and ACE polymorphisms and stroke. The APOE ε2ε4 genotype showed increased risk for hemorrhagic stroke (P<0.05) and also a ...

The common apolipoprotein E (apoE) gene (APOE) epsilon2/epsilon3/epsilon4 polymorphism explains part of serum lipid variation, and polymorphisms in the APOE promoter region have been proposed to participate in the regulation of serum lipid levels within the most common APOE epsilon3/epsilon3 genotype group. We determined APOE -219G/T and +113G/C promoter genotypes and estimated APOE haplotypes ...

OBJECTIVE The results of many studies revealed that estrogen plus progestogen therapy (EPT) may modify dementia development risk in relation to the apolipoprotein E gene (APOE) polymorphisms. However, the mechanism and subsequently clinical importance of such an effect are still unexplained. The objective of this study was to explore the influence of EPT on cognitive functioning of women in the...

Ischemic stroke (IS), the leading neurology cause of death and disability worldwide, is influenced by gene polymorphisms. To explore the association between IS and Apolipoprotein E (APOE) gene polymorphisms, a case-control study containing 513 IS patients and 514 controls without IS was conducted in a Northwest China Han population. MassARRAY iPLEX system was applied to determine the APOE polym...

Possession of the apolipoprotein E (APOE) epsilon4 allele is the most frequently associated genetic susceptibility factor for Alzheimer's disease (AD). Recently, new polymorphisms in the regulatory region of the APOE gene have been described. We analysed the effects of three of these mutations (-491 AT, -427 CT and Th1/E47cs) on disease risk in a large case-control study, and tested their impac...

BACKGROUND Apolipoprotein E gene (APOE) interacts with environmental factors in defining risk for atherosclerosis. We studied whether the APOE epsilon2/epsilon3/epsilon4 genotype or APOE promoter polymorphisms -219G/T and +113G/C might interact with smoking on the development of fatty streaks. We also studied the previously unknown effects of +113G/C on transcriptional activity. METHODS AND R...

OBJECTIVE Genetic variability in the NR1H3 gene (encoding LXRα) and in several of its target genes is associated with serum HDL-cholesterol (HDL-C) concentrations. We sought to assess if these associations could be detected in adolescents. METHODS Thirty-nine polymorphisms in NR1H3, ABCA1, APOE, CETP, PLTP and LPL were analysed in the HELENA study (n = 1144 European adolescents). RESULTS Th...
