Abstract

Mammalian genomes are organized into megabase-scale topologically associated domains (TADs). We demonstrate that disruption of TADs can rewire long-range regulatory architecture and result in pathogenic phenotypes. We show that distinct human limb malformations are caused by deletions, inversions, or duplications altering the structure of the TAD-spanning WNT6/IHH/EPHA4/PAX3 locus. Using CRISPR/Cas genome editing, we generated mice with corresponding rearrangements. Both in mouse limb tissue and patient-derived fibroblasts, disease-relevant structural changes cause ectopic interactions between promoters and non-coding DNA, and a cluster of limb enhancers normally associated with Epha4 is misplaced relative to TAD boundaries and drives ectopic limb expression of another gene in the locus. This rewiring occurred only if the variant disrupted a CTCF-associated boundary domain. Our results demonstrate the functional importance of TADs for orchestrating gene expression via genome architecture and indicate criteria for predicting the pathogenicity of human structural variants, particularly in non-coding regions of the human genome.

  • Loss of TAD insulation between limb-specific enhancers associated with EPHA4 expression and adjacent genes including WNT6 and PAX3 results in their misexpression and abnormal limb development in both mice and humans.

    “loss of TAD insulation between limb-specific enhancers associated with EPHA4 expression and a set of adjacent genes, including WNT6 and PAX3, results in their misexpression and abnormal limb development in both mice and humans [446].”

    From Transcriptional enhancers and their communication with gene promoters (2021) · cites this paper as [446]

    The Results sections on structural changes and enhancer interactions report Pax3 and Wnt6 misexpression in mutant mouse limbs and new contacts with enhancers in the Epha4 TAD. The Discussion section on conservation reports corresponding abnormal chromatin interactions in patient fibroblasts, but does not demonstrate WNT6 or PAX3 misexpression in developing human limbs; it presents the link to human limb phenotypes as a plausible explanation, not an established result. Page numbers were not provided in our copy. (LLM, conf=0.86)

  • Genomic changes that remove CTCF-associated boundaries permit abnormal enhancer-gene interactions and change gene expression.

    “Genomic alterations that remove CTCF-associated boundaries allow aberrant enhancer-gene interactions and alter gene expression17.”
  • CRISPR technology has recently made it much more straightforward to delete genomic sequences in the mouse, enabling new insights into enhancer redundancy and consequences of disrupting TADs.

    “Second, CRISPR technology has recently made it much more straightforward to delete genomic sequences in the mouse, enabling new insights into aspects such as enhancer redundancy115 and the consequences of disrupting TADs220.”
  • TADs appear to restrict the areas of enhancer action.

    “Second, it was demonstrated that eukaryotic chromosomes are partitioned into so-called topologically associated domains (TADs) [35,36,37], which appear to restrict the areas of enhancer action [38,39,40,41].”

    From Enhancer Function in the 3D Genome (2023) · cites this paper as [39]

  • CTCF mediates enhancer-blocking insulation through the specification of TAD boundaries.

    “This observation supports at the genome-wide level the notion that CTCF can mediate enhancer-blocking insulation through the specification of TAD boundaries, in line with previous locus-specific studies (Dowen et al., 2014; Doyle et al., 2014; Lupiáñez et al., 2015; Nora et al., 2012).”

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.
