Abstract

Although plasma proteins have important roles in biological processes and are the direct targets of many drugs, the genetic factors that control inter-individual variation in plasma protein levels are not well understood. Here we characterize the genetic architecture of the human plasma proteome in healthy blood donors from the INTERVAL study. We identify 1,927 genetic associations with 1,478 proteins, a fourfold increase on existing knowledge, including trans associations for 1,104 proteins. To understand the consequences of perturbations in plasma protein levels, we apply an integrated approach that links genetic variation with biological pathway, disease, and drug databases. We show that protein quantitative trait loci overlap with gene expression quantitative trait loci, as well as with disease-associated loci, and find evidence that protein biomarkers have causal roles in disease using Mendelian randomization analysis. By linking genetic factors to diseases via specific proteins, our analyses highlight potential therapeutic targets, opportunities for matching existing drugs with new disease indications, and potential safety concerns for drugs under development.

  • The pleiotropic loci included well-established, previously identified pleiotropic loci such as MHC, ABO, ZFPM2, ARHGEF3, GCKR, SERPINA1, SH2B3 and ASGR1.

    “These included well-established, previously identified [17][18][19][20] pleiotropic loci such as MHC, ABO, ZFPM2, ARHGEF3, GCKR, SERPINA1, SH2B3 and ASGR1”

    From Plasma proteomic associations with genetics and health in the UK Biobank (2023) · cites this paper as [18]

    In “trans pQTLs identify pathways to disease” (page unavailable), the paper identifies ABO as a well-known pleiotropic locus, describes ZFPM2 as associated with many correlated proteins, and reports associations between a SERPINA1 variant and multiple proteins. It mentions MHC elsewhere but does not identify it there as a pleiotropic locus; the passages found do not establish ARHGEF3, GCKR, SH2B3 or ASGR1 as examples. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Several studies in blood plasma have shown that pQTLs using aptamer-based and antibody-based assays are common and can explain up to 30% of protein variance.

    “several studies in blood plasma have consistently shown that genetic variants associated with protein levels, known as protein quantitative trait loci (pQTL), using both aptamer‐based (Sun et al, 2018; Ferkingstad et al, 2021) and antibody‐based assays (Folkersen et al, 2020) are common and can explain up to 30% of the protein variance.”

    From The genetic regulation of protein expression in cerebrospinal fluid (2023) · cites this paper as Sun et al, 2018

    The Methods (Protein measurements) describe the aptamer-based SOMAscan assay, and Genetic architecture of the plasma proteome reports 1,927 pQTLs, supporting the claim that such associations are common in plasma. That section reports a median of 5.8% of protein-level variation explained and more than 20% for 193 proteins, but does not establish the cited figure of up to 30%. The antibody-based studies are attributed to other citations in the sentence, not to Sun et al. (LLM, conf=0.83)

    Experimental — accuracy not yet measured
  • Of 1021 independent autosomal lead pQTL variants for 1478 proteins from the large-scale pQTL study by Sun et al., 824 (80.7%) were present in the EstBB WGS dataset.

    “We used data on 1021 independent autosomal lead pQTL variants for 1478 proteins from the large-scale pQTL study conducted by Sun et al.4; 824 (80.7%) of these variants were present in the EstBB WGS dataset.”

    From Genetic determinants of plasma protein levels in the Estonian population (2024) · cites this paper as Sun et al. [4]

    The ‘Genetic architecture of the plasma proteome’ section reports pQTL associations involving 1,478 proteins and describes sentinel variants, supporting the identification of Sun et al. as the pQTL study used. Our copy does not establish the specific count of 1,021 independent autosomal lead variants (searched: ‘1,021 independent autosomal lead pQTL variants’ and ‘1021 sentinel variants’). The 824-variant overlap with EstBB WGS is presented as the citing authors’ own finding, not a finding attributed to Sun et al. No page number was provided for the indexed passages. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • We identified eight CNVs with possible effects on protein levels from the Sun et al. 2018 study.

    “We identified eight CNVs with possible effects on protein levels (Table 2) from the Sun et al. 2018 study4.”

    From Genetic determinants of plasma protein levels in the Estonian population (2024) · cites this paper as [4]

    The Genetic architecture of the plasma proteome section reports associations between genetic variants and protein levels, so Sun et al. is a relevant source for that part of the sentence. Our copy does not identify eight CNVs or establish that CNVs were among the variants used; the claim's CNV-specific link to this study is therefore unsupported. (LLM, conf=0.78)

    Experimental — accuracy not yet measured
  • cis-pQTL effect sizes correlate with proximity to the protein coding gene.

    “We also confirmed previous evidence10,13 that cis-pQTL effect sizes correlate with proximity to the protein coding gene (Fig. 2D; Supp. Fig. 3H).”

    From Proteogenomic analysis of human cerebrospinal fluid identifies neurologically relevant regulation and implicates causal proteins for Alzheimer’s disease (2024) · cites this paper as [13]

    The Genetic architecture of the plasma proteome section (page unavailable) reports that cis-pQTL association P values increased with distance from the protein-coding gene’s transcription start site. It does not report a correlation between effect sizes and distance; P values measure statistical significance, not effect size. (LLM, conf=0.82)

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.
