Abstract

Human gut microbiome composition is shaped by multiple factors but the relative contribution of host genetics remains elusive. Here we examine genotype and microbiome data from 1,046 healthy individuals with several distinct ancestral origins who share a relatively common environment, and demonstrate that the gut microbiome is not significantly associated with genetic ancestry, and that host genetics have a minor role in determining microbiome composition. We show that, by contrast, there are significant similarities in the compositions of the microbiomes of genetically unrelated individuals who share a household, and that over 20% of the inter-person microbiome variability is associated with factors related to diet, drugs and anthropometric measurements. We further demonstrate that microbiome data significantly improve the prediction accuracy for many human traits, such as glucose and obesity measures, compared to models that use only host genetic and environmental data. These results suggest that microbiome alterations aimed at improving clinical outcomes may be carried out across diverse genetic backgrounds.

  • The human microbiome is highly individual-specific, shaped by genetics, diet, age, geography, disease status, and intrinsic host factors.

    “This can be attributed to the highly individual-specificity of the human microbiome,10,11 shaped by genetics, diet, age, geography, disease status, and intrinsic host factors.12”

    From Gut microbiota drives structural variation of exogenous probiotics to enhance colonization (2025) · cites this paper as [12]

    The paper’s main findings report that diet, lifestyle and anthropometric factors are associated with differences in gut microbiome composition; its Microbiome-environment associations section also considers age and glycaemic status. But the study concerns healthy Israeli individuals and does not establish geography or disease status as shaping factors. It finds that host genetics have only a minor role, rather than presenting genetics as a major determinant. (LLM, conf=0.86)

  • Adult microbial communities seem to be predominantly shaped by prior stochastic environmental exposures, as well as multiple other factors such as diet, antibiotic therapy and host genetics, with direct 'inheritance' from the mother at birth playing a lesser role.

  • Proportionally few microbiota species are truly 'heritable' and persist from birth to adulthood in the offspring.

    “proportionally few microbiota species are truly 'heritable' and persist through from birth to adulthood in the offspring 15,16 .”

    From Human microbiome myths and misconceptions (2023) · cites this paper as [16]

    The Discussion (page unavailable) says that only a small number of bacterial taxa are likely to be strongly heritable. It does not establish that those taxa persist in offspring from birth to adulthood; the Discussion says the determinants of microbiome stability over time remain unresolved. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Diet is a major factor shaping the composition and function of the gut microbiota.

    “Diet has emerged as a driving factor in microbiota composition and function (Flint et al., 2017; Muegge et al., 2011; Rothschild et al., 2018; Zhernakova et al., 2016).”

    From Gut-microbiota-targeted diets modulate human immune status (2021) · cites this paper as Rothschild et al., 2018

  • The effect size of host genetics on the gut microbiome is likely small because microbial-genetic association studies show environmental factors have substantially greater impact.

    “However, the effect size is likely small given recent microbial-genetic association studies showing environmental factors to have substantially greater impact on the gut microbiome than genetics22.”

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.
