Abstract

Late-onset Alzheimer’s disease is a prevalent age-related polygenic disease that accounts for 50–70% of dementia cases. Currently, only a fraction of the genetic variants underlying Alzheimer’s disease have been identified. Here we show that increased sample sizes allowed identification of seven previously unidentified genetic loci contributing to Alzheimer’s disease. This study highlights microglia, immune cells and protein catabolism as relevant to late-onset Alzheimer’s disease, while identifying and prioritizing previously unidentified genes of potential interest. We anticipate that these results can be included in larger meta-analyses of Alzheimer’s disease to identify further genetic variants that contribute to Alzheimer’s pathology. A genome-wide association study performed in 1,126,563 individuals identifies seven new loci associated with Alzheimer’s disease and implicates microglia and immune cells in late-onset disease.

  • More than 90 genetic loci are associated with Alzheimer's disease and related dementia (ADRD).

    “More than 90 genetic loci are associated with Alzheimer’s disease and related dementia (ADRD).”

    From Consensus meta-analysis of genome-wide association studies for Alzheimer’s disease and related dementias (2026) · cites this paper as [5]

    The Genome-wide inferences section reports 38 independent loci associated with late-onset Alzheimer’s disease, not more than 90. The paper does not report a count of more than 90 loci for Alzheimer’s disease and related dementia. (LLM, conf=0.88)

    Checked by a reasoning model — may be wrong.

  • Nine loci (APP, CCDC6, GRN, LILRB2, NCK2, TNIP1, TMEM106B, TSPAN14 and SHARPIN) were recently reported in three articles using part of the GWAS data included in the study.

    “Nine of these loci (APP, CCDC6, GRN, LILRB2, NCK2, TNIP1, TMEM106B, TSPAN14 and SHARPIN) were recently reported in three articles using part of the GWAS data included in our study11–13.”

    From New insights into the genetic etiology of Alzheimer’s disease and related dementias (2022) · cites this paper as [13]

    Table 1 (Functional enrichment of significantly associated regions; page unavailable) lists eight of the nine named loci as GWAS risk loci. It does not list TSPAN14, and this source alone does not establish that the three cited articles collectively reported all nine loci or used part of the citing study’s data. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • Independent association signals detected in the CD33, HLA, PICALM and RHOH loci are new compared to refs. 4-6,9.

    “Compared to refs. 4–6,9, the independent association signals detected in the CD33, HLA, PICALM and RHOH loci are new”

    From Consensus meta-analysis of genome-wide association studies for Alzheimer’s disease and related dementias (2026) · cites this paper as [5]

    Table 1 and the Genome-wide inferences section (page unavailable) report associations at CD33, HLA-DRB1 and PICALM among 38 independent loci. They do not establish that signals at those loci are new relative to refs. 4–6,9, and the passages found do not identify a RHOH signal. (LLM, conf=0.79)

    Experimental — accuracy not yet measured
  • Recent GWAS have identified several genes associated with AD that are predominantly or exclusively expressed in myeloid cells, including INPP5D.

    “Recent genome-wide association studies (GWAS) have identified several genes associated with AD that are predominantly or exclusively expressed in myeloid cells, including INPP5D (inositol polyphosphate 5-phosphatase 1), which encodes SHIP17–10.”

    From INPP5D/SHIP1 regulates endo-lysosomal function and cargo-selective phagocytosis in human microglia (2025) · cites this paper as [10]

    The Tissue type, cell type and gene-set enrichment section (page unavailable) reports that Alzheimer’s-associated genes are enriched in microglia, supporting the broad link between GWAS findings and immune-related cells. The passages do not identify INPP5D as an associated gene or establish that it is predominantly or exclusively expressed in myeloid cells; searches for INPP5D and myeloid-cell expression found no such passage. (LLM, conf=0.82)

    Experimental — accuracy not yet measured
  • Large-scale GWAS meta-analyses have highlighted immune and myeloid cell pathways as major contributors to Alzheimer's disease risk and progression, even when individual genes do not reach genome-wide significance thresholds.

    “Large-scale GWAS meta-analyses have highlighted immune and myeloid cell pathways as major contributors to Alzheimer’s disease risk and progression, even when individual genes do not reach genome-wide significance thresholds [97].”

    From Genetic drivers of progression in Alzheimer’s disease are distinct from disease risk (2026) · cites this paper as [97]

    The Tissue type, cell type and gene-set enrichment section (page unavailable) reports significant immune-cell recruitment gene sets and microglial enrichment, supporting a role in late-onset Alzheimer’s disease risk. It does not establish an effect on disease progression or say that these pathway findings persist when individual genes fail to reach genome-wide significance. (LLM, conf=0.86)

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.
