Abstract

Genome-wide association studies (GWAS) have identified over 300 regions associated with more than 70 common diseases. However, identifying causal genes within an associated region remains a major challenge. One approach to resolving causal genes is through the dissection of gene-phenotype correlations. Here we use polychromatic flow cytometry to show that differences in surface expression of the human interleukin-2 (IL-2) receptor alpha (IL2RA, or CD25) protein are restricted to particular immune cell types and correlate with several haplotypes in the IL2RA region that have previously been associated with two autoimmune diseases, type 1 diabetes (T1D) and multiple sclerosis. We confirm our strongest gene-phenotype correlation at the RNA level by allele-specific expression (ASE). We also define key parameters for the design and implementation of post-GWAS gene-phenotype investigations and demonstrate the usefulness of a large bioresource of genotype-selectable normal donors from whom fresh, primary cells can be analyzed.

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

  • T-cell surface expression of IL-12 receptor alpha (CD25) is associated with risk variants for both MS and type 1 diabetes.

    “T‐cell surface expression of IL‐12 receptor alpha (CD25) is associated with risk variants for both MS and type 1 diabetes.72”

    From Genome‐wide association studies of multiple sclerosis (2018) · cites this paper as [72]

    The paper’s main text reports that IL2RA risk-related haplotypes correlate with surface CD25 expression on CD4+ T-cell subsets, and discusses phenotypes implicated in both type 1 diabetes and multiple sclerosis. But the claim misidentifies CD25 as IL-12 receptor alpha; the paper identifies it as IL-2 receptor alpha (IL2RA). Our copy provides no page number for these passages. (LLM, conf=0.90)

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.
