Imaging and rare APOE alleles: Alzheimer disease as a developmental disorder
Abstract
The association between genetic variants in APOE and risk of Alzheimer disease (AD) is well known and there exists a considerable body of research into how the 3 major isoforms of APOE -encoded ApoE (ε2, ε3, and ε4) contribute to AD pathology.1 These investigations have largely focused on how these different isoforms differentially modulate β-amyloid aggregation and clearance, but a growing body of research suggests these alleles also have important developmental effects that may set up a neuroanatomical vulnerability to AD. Shaw et al.2 were the first to demonstrate that ε4 carriers exhibited cortical thinning and reduced volumes in AD-vulnerable brain regions during adolescence. Several years later, Knickmeyer et al.3 demonstrated that this effect was already present at birth, suggesting an origin in prenatal brain development. Complementary work in mice expressing human ApoE isoforms indicated that the ε4 allele reduces dendritic spine density as early as 1 month of age (approximately equivalent to a prepubertal child). The ε2 allele resulted in longer dendritic spines and increased complexity at 1 month of age.4 In addition, several studies have reported better cognitive performance in young ε4 carriers, indicating possible pleiotropic effects on cognition across the lifespan, such that ε4-related benefits in childhood reverse to become risk factors for cognitive impairment and dementia in later life.5 However, a 2012 meta-analysis found no beneficial results of the ε4 allele on cognition in children, adolescents, and young adults.6

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.
