Abstract

OBJECTIVES: To provide risk estimates of dementia and Alzheimer disease as a function of the apolipoprotein E (APOE) genotypes and to assess the proportion of dementia that is attributable to the APOE genotypes. DESIGN: Case-control study nested in a population-based cohort study with a mean (SD) follow-up of 2.1 (0.9) years. SETTING: General population in Rotterdam, the Netherlands. PARTICIPANTS: A total of 134 patients with incident dementia and a random sample of 997 nondemented control subjects. No participant had dementia at baseline. MAIN OUTCOME MEASURES: Odds ratios for dementia and Alzheimer disease, the fraction of dementia attributable to the APOE epsilon4 allele, and the proportion of the variance in age at the onset of dementia explained by the APOE genotypes. RESULTS: Persons with the epsilon4/4 genotype had a more than 10-fold higher risk of dementia (odds ratio, 11.2; 95% confidence interval, 3.6-35.2), and subjects with the epsilon3/4 genotype had a 1.7-fold increased risk of dementia (95% confidence interval, 1.0-2.9) as compared with persons with the epsilon3/3 genotype. The proportion of patients with dementia that is attributable to the epsilon4 allele was estimated to be 20%. The APOE genotypes explained up to 10% of the variance in age at the onset of dementia. The association between the epsilon4 allele and dementia was strongest in the youngest age category and in those with a family history of dementia. CONCLUSIONS: The APOE genotype is an important determinant of the risk of dementia. At a population level, however, other factors than the APOE genotype may play an important role in the cause of dementia.

  • APOE remains the only locus repeatedly associated with AAO, but PICALM and BIN1 have also been reported to affect AAO.

    “To date, APOE remains the only locus repeatedly associated with AAO8,9, but PICALM and BIN1 have also been reported to affect AAO6,10,11.”

    The Comment section reports that APOE genotypes explained some variance in age at onset of dementia, supporting the APOE–AAO association. The paper does not establish that APOE was the only locus repeatedly associated with AAO; its introduction says APOE's role in age at onset was still controversial. PICALM and BIN1 are attached to other citations in the citing sentence, not this one. Page numbers are unavailable in our copy. (LLM, conf=0.85)

  • Genes linked to early-onset AD risk that are expressed primarily in microglia include TREM2, MS4A, ABCA7, ApoE4, CD33, PU.1, and BIN1.

    “Genetic studies show that a number of genes that have been linked to early-onset AD risk are expressed primarily in microglia.”

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.
