Abstract

Over the course of an individual's lifetime, normal human cells accumulate mutations 1. Here we compare the mutational landscape in 29 cell types from the soma and germline using multiple samples from the same individuals. Two ubiquitous mutational signatures, SBS1 and SBS5/40, accounted for the majority of acquired mutations in most cell types, but their absolute and relative contributions varied substantially. SBS18, which potentially reflects oxidative damage 2, and several additional signatures attributed to exogenous and endogenous exposures contributed mutations to subsets of cell types. The rate of mutation was lowest in spermatogonia, the stem cells from which sperm are generated and from which most genetic variation in the human population is thought to originate. This was due to low rates of ubiquitous mutational processes and may be partially attributable to a low rate of cell division in basal spermatogonia. These results highlight similarities and differences in the maintenance of the germline and soma.

  • Selected and more fit clones may share genomic events such as nonsynonymous mutations initially thought to be restricted to cancer.

    “Interestingly, these selected and more fit clones may share genomic events such as nonsynonymous mutations initially thought to be restricted to cancer.17-24”

    From Evolution of Multiple Myeloma from a Genomic Perspective (2026) · cites this paper as [23]

    Clonal structures in normal tissues (p. 3) reports cancer-driver mutations in normal tissues and describes such mutations as conferring a selective advantage. Identification of Cancer Driver Mutations (p. 23) includes missense mutations at validated cancer hotspots, supporting the nonsynonymous-mutation example. The copy does not establish that these events were initially thought to be restricted to cancer. (LLM, conf=0.82)

  • Across most, if not all, tissues, after an initial expansion of the stem cell pool during early life, clonal heterogeneity tends to diminish over time.

    “A consistent pattern has been observed across most, if not all, tissues: after an initial expansion of the stem cell pool during early life, clonal heterogeneity tends to diminish over time (Figure 1).17-24”

    From Evolution of Multiple Myeloma from a Genomic Perspective (2026) · cites this paper as [23]

    The Clonal structures in normal tissues section (p. 3) describes how clonal architecture differs among adult tissues, and the Discussion (p. 6) emphasizes variation in clonal dynamics. Neither passage establishes an early-life expansion of the stem-cell pool followed by declining clonal heterogeneity across most tissues; searches for age-related loss of clonal diversity found no such account in our copy. (LLM, conf=0.72)

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.
