Cortical morphology in children and adolescents with different apolipoprotein E gene polymorphisms: an observational study
Abstract
Background Alleles of the apolipoprotein E (APOE) gene modulate risk for Alzheimer's disease, with carriers of the epsilon4 allele being at increased risk and carriers of the epsilon2 allele possibly at decreased risk compared with non-carriers. Our aim was to determine whether possession of an epsilon4 allele would confer children with a neural substrate that might render them at risk for Alzheimer's disease, and whether carriers of the epsilon2 allele might have a so-called protective cortical morphology. Methods 239 healthy children and adolescents were genotyped and had repeated neuroanatomic MRI (total 530 scans). Mixed model regression was used to determine whether the developmental trajectory of the cortex differed by genotype. Findings Cortical thickness of the left entorhinal region was significantly thinner in epsilon4 carriers than it was in non-epsilon4 carriers (3.79 [SE 0.06] mm, range 1.54-5.24 vs 3.94 [0.03] mm, 2.37-6.11; p=0.03). There was a significant stepwise increase in cortical thickness in the left entorhinal regions, with epsilon4 carriers having the thinnest cortex and epsilon2 carriers the thickest, with epsilon3 homozygotes occupying an intermediate position (left beta 0.11 [SE 0.05], p=0.02). Neuroanatomic effects seemed fixed and non-progressive, with no evidence of accelerated cortical loss in young healthy epsilon4 carriers. Interpretation Alleles of the apolipoprotein E gene have distinct neuroanatomic signatures, identifiable in childhood. Th…

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.
