Effects of apolipoprotein E genotype on cortical neuropathology in senile dementia of the Lewy body and Alzheimer's disease
R Benjamin et al. Neurodegeneration. 1995 Dec.
Abstract
Apolipoprotein E (APO E) genotypes were determined in a UK population of neuropathologically confirmed control cases, and in cases of Lewy body dementia (SDLT) and late onset Alzheimer's disease (AD). APO E epsilon 4 allele frequency was significantly elevated in both SDLT and AD groups with a concomitant reduction in the APO E epsilon 3 allele frequency. The epsilon 2 allele frequency in the AD group was only 25% of the control population, though because of the relatively small sample size this reduction was not significant; the epsilon 2 allele frequency in the SDLT group was normal. No significant association was found between senile plaque density and neurofibrillary tangle density in the neocortex and APO E allele dose in either SDLT or AD. Although the possession of APO E epsilon 4 is associated with an increased risk of developing SDLT and AD, actual APO E genotype does not appear to affect the burden of pathology.
