High Frequency of Apolipoprotein E ϵ4 Allele in Young Individuals with Very Mild Alzheimer's Disease-Related Neurofibrillary Changes

Ghebremedhin, Estifanos, Schultz, Christian, Braak, Eva, Braak, Heiko·1998·Experimental Neurology

Abstract

The pathological process of initial neurofibrillary (NF) changes underlying Alzheimer's disease (AD) represents the early preclinical phase of the disease. In a small percentage of individuals, these initial NF changes (Braaks' stage I of six stages) may develop at a surprisingly young age. The aim of this study was to determine the impact of apolipoprotein E (ApoE) on the development of such initial NF changes in young individuals. To this end, the ApoE genotypes were determined using a seminested polymerase chain reaction assay followed by restriction isotyping in young individuals (n = 44; mean age of 38 years) with initial NF changes (stage I). The results were compared with ApoE genotypes of age-matched controls (n = 70) devoid of such changes (stage 0). Stage I cases exhibited a significantly higher epsilon4 allele frequency compared to controls (0.18 vs 0.09, P = 0.039). Thus, the present study reveals an association of epsilon4 allele with the early onset of AD-related NF changes in young individuals. This finding underlines the relevance of the asymptomatic phase in the course of AD.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
