Subgroup analysis revealed that APOE ε4, 2 alleles were not associated with an increased risk of MS in Caucasian population (OR(c-ε4)=0.924, 95% CI=0.819-1.041; OR(c-ε2)=1.127, 95% CI=0.955-1.331).
Inheritance of the apolipoprotein E (APOE) epsilon4 allele is associated with increased risk of Alzheimer disease, progression to disability in multiple sclerosis, and poor outcome after traumatic brain injury.
To investigate the association between apolipoprotein E (Apo E) genotype in multiple sclerosis (MS) and acute monosymptomatic optic neuritis (ON) in a genetically homogeneous population with a high frequency of the Apo epsilon4 allele.

Despite pleiotropic immunomodulatory effects of apolipoprotein E (apoE) in vitro, its effects on the clinical course of experimental autoimmune encephalomyelitis (EAE) and multiple sclerosis (MS) are still controversial.
While part of the association of the apoE polymorphism with AD is supposed to be caused by apoE-isoform dependent effects on amyloid-beta deposition, no single pathogenetically relevant mechanism has yet been confirmed for MS.
The presence of significant NBV decreases only in the group of RRMS patients with the ApoE epsilon4 genotype provides new evidence that links ApoE epsilon4-related impaired mechanisms of cell repair and severe tissue destruction in MS.
Apolipoprotein E ε4-positive multiple sclerosis patients develop more gray-matter and whole-brain atrophy: a 15-year disease history model based on a 4-year longitudinal study.
The influence of APOE allelic heterogeneity on multiple sclerosis (MS) disease severity has been reported in multiple datasets with conflicting results.
The authors studied the association of an exon 4 (E4*epsilon2/3/4) and three promoter polymorphisms of APOE with disease course and severity stratified by gender in 221 patients with multiple sclerosis from two overlapping population-based prevalence cohorts.
Given the large sample size of our analyses, it is unlikely that the two APOE missense SNPs studied here exert any relevant effects on MS susceptibility.
The purpose of the present study was to determine whether the ε4 allele of APOE is associated with more extensive brain pathology in MS using structural and diffusion tensor MRI.
An analysis of disease progression in 614 patients with MS from 379 families indicated that APOE-4 carriers are more likely to be affected with severe disease (P=.03), whereas a higher proportion of APOE-2 carriers exhibit a mild disease course (P=.02).
