Abstract

Key Points: Whole-genome sequencing of 11 262 Icelanders reveals that clonal hematopoiesis is very common in the elderly. Somatic mutation of some genes is strongly associated with clonal hematopoiesis, but in most cases, no driver mutations were evident.

  • All of the Alzheimer's disease-enriched genes represent critical tumor suppressor genes widely implicated in various cancers and clonal hematopoiesis.

    “All of these AD-enriched genes represent critical TSGs widely implicated in various cancers33 and CH34.”

    From Somatic cancer variants enriched in Alzheimer’s disease microglia-like cells drive inflammatory and proliferative states (2026) · cites this paper as [34]

    The 'Association of driver mutations with clonal hematopoiesis' section reports significant CH associations for several genes, including TET2, DNMT3A, ASXL1, and PPM1D. It does not identify the citing paper’s AD-enriched genes or establish that all of them are implicated in CH. The separate cancer citation (33) is not assessed here. (LLM, conf=0.83)

    Experimental — accuracy not yet measured
  • Alzheimer's disease patients showed missense variants in TET2 that clustered in its critical oxygenase domains, a similar mutational pattern to that seen in clonal hematopoiesis, which was not observed in aged controls.

    “AD patients also showed missense variants in TET2 that clustered in its critical oxygenase domains (Figure 2F), a similar mutational pattern to that seen in CH34 (Figure S2D) that was not observed in our aged controls.”

    From Somatic cancer variants enriched in Alzheimer’s disease microglia-like cells drive inflammatory and proliferative states (2026) · cites this paper as [34]

    The ‘Association of driver mutations with clonal hematopoiesis’ section reports that TET2 mutations are significantly associated with CH. Our copy does not describe TET2 missense variants clustering in oxygenase domains, so it does not establish the specific mutational-pattern similarity for which this source is cited. The AD patients and aged controls are the citing authors’ own observations, not findings attributed to this source. (LLM, conf=0.81)

    Experimental — accuracy not yet measured
  • Most Alzheimer's disease somatic variants in ASXL1 were nonsense variants broadly distributed across the encoded protein, including two recurrent alleles observed in AD patients, similar to ASXL1 variants in clonal hematopoiesis events of blood.

    “Most AD somatic variants in ASXL1 were nonsense variants broadly distributed across the encoded protein, including two recurrent alleles observed in AD patients, similar to what is seen in ASXL1 variants in CH events of blood34 (Figure S2D).”

  • CH is associated with chronic obstructive pulmonary disease and other pulmonary disease.

    “Various other systemic effects have been described in association with CH, including chronic obstructive pulmonary disease and other pulmonary disease [16,33,34]”

    From Clonal hematopoiesis and inflammation – the perpetual cycle (2023) · cites this paper as [16]

    In “Association of CH with other phenotypes” (page not provided), the paper reports a significant association between CH, measured by WGS-outlier status, and chronic pulmonary disease. It does not report a separate association with chronic obstructive pulmonary disease (COPD); COPD appears elsewhere as a variable used for adjustment. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • CHIP is an age-related condition affecting over 10-20% of individuals older than 70 years.

    “Clonal hematopoiesis of indeterminate potential (CHIP) is an age-related condition affecting over 10–20% of individuals older than 70 years”

    From Clonal Hematopoiesis of Indeterminate Potential as an Emerging Interdisciplinary Risk Factor in Alzheimer’s Disease: Current Evidence and Future Directions (2026) · cites this paper as [3]

    The section ‘Clonal hematopoiesis is very common in the elderly’ reports that clonal hematopoiesis increases with age and exceeds 50% among people older than 85. It does not establish the claimed 10–20% prevalence for CHIP specifically among people older than 70; its whole-genome measure includes cases without candidate driver mutations. (LLM, conf=0.85)

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.
