Alzheimer’s disease: rare variants with large effect sizes

Abstract

Recent advances in sequencing technology and novel genotyping arrays (focused on low-frequency and coding variants) have made it possible to identify novel coding variants with large effect sizes and also novel genes (TREM2, PLD3, UNC5C, and AKAP9) associated with Alzheimer's disease (AD) risk. The major advantages of these studies over the classic genome-wide association studies (GWAS) include the identification of the functional variant and the gene-driven association. In addition to the large effect size, these studies make it possible to model these variants and genes using cell and animal systems. On the other hand, the underlying population-variability of these very low allele frequency variants poses a great challenge to replicating results. Studies that include very large datasets (>10,000 cases and controls) and combine sequencing and genotyping approaches will lead to the identification of novel genes for Alzheimer's disease.

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.
