Abstract

The Wellcome Trust Case Control Consortium (WTCCC) primary genome-wide association (GWA) scan on seven diseases, including the multifactorial autoimmune disease type 1 diabetes (T1D), shows associations at P < 5 × 10−7 between T1D and six chromosome regions: 12q24, 12q13, 16p13, 18p11, 12p13 and 4q27. Here, we attempted to validate these and six other top findings in 4,000 individuals with T1D, 5,000 controls and 2,997 family trios independent of the WTCCC study. We confirmed unequivocally the associations of 12q24, 12q13, 16p13 and 18p11 (Pfollow-up ≤ 1.35 × 10−9; Poverall ≤ 1.15 × 10−14), leaving eight regions with small effects or false-positive associations. We also obtained evidence for chromosome 18q22 (Poverall = 1.38 × 10−8) from a GWA study of nonsynonymous SNPs. Several regions, including 18q22 and 18p11, showed association with autoimmune thyroid disease. This study increases the number of T1D loci with compelling evidence from six to at least ten.

  • Genome-wide association studies have confirmed a number of non-HLA genetic factors that increase the risk of a first appearing b-cell autoantibody or type 1 diabetes, both in first degree relatives of individuals with type 1 diabetes and in the general population.

    “Genome-wide association studies have confirmed a number of non-HLA genetic factors that increase the risk of a first appearing b-cell autoantibody or type 1 diabetes, both in first degree relatives of individuals with type 1 diabetes and in the general population (386,387,404,405).”

    From Guidelines and Recommendations for Laboratory Analysis in the Diagnosis and Management of Diabetes Mellitus (2023) · cites this paper as [405]

    The Abstract reports confirmed associations between non-HLA chromosome regions and type 1 diabetes in independent cases and controls and in parent–child trios. It does not report whether these factors increase the risk of a first-appearing β-cell autoantibody, so that part of the citing sentence is unsupported by this paper. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • GWAS confirm that non-HLA factors INS, VNTR, CTLA4, PTPN22, and others raise type 1 diabetes risk in first-degree relatives and the general population.

    “Genomewide association studies have confirmed that the following non-HLA genetic factors increase the risk for type 1 diabetes, both in first-degree relatives of type 1 diabetic patients and in the general population: INS, VNTR, CTLA4, PTPN22, and others (263,265,282,283).”

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.
