Abstract

We present a method for testing overrepresentation of biological pathways, indexed by gene-ontology terms, in lists of significant SNPs from genome-wide association studies. This method corrects for linkage disequilibrium between SNPs, variable gene size, and multiple testing of nonindependent pathways. The method was applied to the Wellcome Trust Case-Control Consortium Crohn disease (CD) data set. At a general level, the biological basis of CD is relatively well known for a complex genetic trait, and it thus acted as a test of the method. The method, known as ALIGATOR (Association LIst Go AnnoTatOR), successfully detected biological pathways implicated in CD. The method was also applied to a meta-analysis of bipolar disorder, and it implicated the modulation of transcription and cellular activity, including that which occurs via hormonal action, as an important player in pathogenesis.

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

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

  • Analyses of bipolar disorder provided evidence of association with hormone action and adherens junctions.

    “Analyses of bipolar disorder provided evidence of association with hormone action and adherens junctions7,9,10”
  • INRICH, ALIGATOR, and MAGENTA are best-SNP-per-gene methods that count pathway genes with independent SNPs above a significance threshold, correcting for LD and genomic structure via Monte-Carlo simulation.

    “INRICH45, ALIGATOR9 and MAGENTA46 are “best SNP per gene” methods that count the number of genes in a pathway where a number of independent SNPs exceed a predefined significance, and adjust for LD and genomic structure with corrected statistics derived by Monte-Carlo simulation.”

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.
