Abstract

The resolution of genome-wide association studies (GWAS) is limited by the linkage disequilibrium (LD) structure of the population being studied. Selecting the most likely causal variants within an LD block is relatively straightforward within coding sequence, but is more difficult when all variants are intergenic. Predicting functional non-coding sequence has been recently facilitated by the availability of conservation and epigenomic information. We present HaploReg, a tool for exploring annotations of the non-coding genome among the results of published GWAS or novel sets of variants. Using LD information from the 1000 Genomes Project, linked SNPs and small indels can be visualized along with their predicted chromatin state in nine cell types, conservation across mammals and their effect on regulatory motifs. Sets of SNPs, such as those resulting from GWAS, are analyzed for an enrichment of cell type-specific enhancers. HaploReg will be useful to researchers developing mechanistic hypotheses of the impact of non-coding variants on clinical phenotypes and normal variation. The HaploReg database is available at http://compbio.mit.edu/HaploReg.

  • rs1057233 changes the target sequence and binding of miR-569.

    “rs1057233 changes the target sequence and binding of miR-56933”

    From A common haplotype lowers PU.1 expression in myeloid cells and delays onset of Alzheimer's disease (2017) · cites this paper as [33]

    The Methods section describes predictions of regulatory motif changes, and the Usage section discusses a different SNP, rs9271055, affecting an Ets-family binding site. Searches for rs1057233 and miR-569 found no passage in our copy addressing their target sequence or binding. (LLM, conf=0.76)

    Experimental — accuracy not yet measured
  • rs1057233 was previously found to be associated with systemic lupus erythematosus, body mass index, and proinsulin levels.

    “Interestingly, rs1057233 was previously found to be associated with systemic lupus erythematosus33, body mass index40 and proinsulin levels41”

    From A common haplotype lowers PU.1 expression in myeloid cells and delays onset of Alzheimer's disease (2017) · cites this paper as [33]

    Citation 33 is attached to the lupus association, not the body-mass-index or proinsulin claims. The USAGE section discusses a lupus GWAS but names rs9271100 and rs9271055, not rs1057233; a search for rs1057233 found no passage linking it to lupus in our copy. (LLM, conf=0.75)

    Experimental — accuracy not yet measured
  • Of 1,873 prioritized variants, 71-99% have regulatory potential when considering all tissues according to RegulomeDB and HaploReg.

    “Of these variants, 71–99% have regulatory potential when considering all tissues according to RegulomeDB56 and HaploReg57”
  • Bioinformatic annotation suggested that the 19p13.3 risk locus contains regulatory elements and that the risk variant(s) might confer disease susceptibility by modulating expression of target genes.

    “Notably, these data suggested the presence of regulatory elements at the identified loci, and therefore the risk variant(s) might confer disease susceptibility by modulating the expression of target genes.”

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.
