Rare and common variants in the Apolipoprotein E gene in healthy oldest old

Abstract

Apolipoprotein E (APOE) alleles are associated with longevity in genome-wide scans, with ε4 correlated with shorter life, and ε2 with longer life, than ε3. We hypothesized that rare APOE variants with large individual effects might also contribute to long-term good health. The APOE exons and promoter were resequenced in DNA samples from 376 healthy oldest old aged ≥ 85 yrs with no self-reported history of cancer, cardiovascular disease, diabetes, major pulmonary disease or Alzheimer disease ("Super-Seniors") and 376 population-based controls aged 41-54. Forty variants were observed: 32 were rare (minor allele frequency <2%); 9 were nonsynonymous. Controls were more likely to have an ε4 allele (Pearson χ(2) = 6.61, p = 0.04). Among the Super-Seniors, APOE allele status was not associated with body mass index or Mini Mental State Examination score. There was no excess of rare APOE variants in healthy oldest old compared with midlife controls, or vice-versa; however, this does not rule out an effect of some variants on ApoE function. Our findings were consistent with ε4 being a risk factor for early mortality.

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.
