Abstract

Structural variation is widespread in mammalian genomes and is an important cause of disease, but just how abundant and important structural variants (SVs) are in shaping phenotypic variation remains unclear. Without knowing how many SVs there are, and how they arise, it is difficult to discover what they do. Combining experimental with automated analyses, we identified 711,920 SVs at 281,243 sites in the genomes of thirteen classical and four wild-derived inbred mouse strains. The majority of SVs are less than 1 kilobase in size and 98% are deletions or insertions. The breakpoints of 160,000 SVs were mapped to base pair resolution, allowing us to infer that insertion of retrotransposons causes more than half of SVs. Yet, despite their prevalence, SVs are less likely than other sequence variants to cause gene expression or quantitative phenotypic variation. We identified 24 SVs that disrupt coding exons, acting as rare variants of large effect on gene function. One-third of the genes so affected have immunological functions.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Wild-derived mouse variants include over 5 million SNPs, 116 novel genes not present in B6, and between 250 and 400 large structural variants.

    “These variants include over 5 million single nucleotide polymorphisms (SNPs; Onos et al., 2019), 116 novel genes not present in B6 (Lilue et al., 2018), and between 250 and 400 large structural variants (Yalcin et al., 2011).”

    From Network analysis identifies strain-dependent response to tau and tau seeding-associated genes (2023) · cites this paper as Yalcin et al., 2011

    The paper reports structural variants in four wild-derived inbred mouse strains, supporting that part of the cited clause. Its Abstract reports 0.71 million variants across all 17 strains, but our copy does not give a count of 250–400 large structural variants. The SNP and novel-gene figures have separate citations and are not assessed here. (LLM, conf=0.82)

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.
