Abstract

Circulating proteins are vital in human health and disease and are frequently used as biomarkers for clinical decision-making or as targets for pharmacological intervention. Here, we map and replicate protein quantitative trait loci (pQTL) for 90 cardiovascular proteins in over 30,000 individuals, resulting in 451 pQTLs for 85 proteins. For each protein, we further perform pathway mapping to obtain trans-pQTL gene and regulatory designations. We substantiate these regulatory findings with orthogonal evidence for trans-pQTLs using mouse knockdown experiments (ABCA1 and TRIB1) and clinical trial results (chemokine receptors CCR2 and CCR5), with consistent regulation. Finally, we evaluate known drug targets, and suggest new target candidates or repositioning opportunities using Mendelian randomization. This identifies 11 proteins with causal evidence of involvement in human disease that have not previously been targeted, including EGF, IL-16, PAPPA, SPON1, F3, ADM, CASP-8, CHI3L1, CXCL16, GDF15 and MMP-12. Taken together, these findings demonstrate the utility of large-scale mapping of the genetics of the proteome and provide a resource for future precision studies of circulating proteins in human health. Folkersen et al. report the first results from the SCALLOP consortium, a collaborative framework for pQTL mapping and biomarker analysis of proteins on the Olink platform. A total of 315 primary and 136 secondary pQTLs for 85 circulating cardiovascular proteins from over 30,000 individuals were identified and replicated to yield new insights for translational studies and drug development.

  • Most pQTLs to date have been discovered via genome-wide association studies, which predominantly focus on common variants.

    “To date, most pQTLs have been discovered via genome-wide association studies (GWASs), which predominantly focus on common variants3,5–8.”

    From Rare variant associations with plasma protein levels in the UK Biobank (2023) · cites this paper as [7]

    The Results section, “Genome-wide meta-analysis of 90 proteins” (page unavailable), reports discovering hundreds of pQTLs through a GWAS meta-analysis, supporting GWAS as a pQTL discovery method. The paper does not establish that most pQTLs discovered to date came from GWAS or that GWAS predominantly focus on common variants; its Online Methods instead describe filtering by a minimum minor-allele count. (LLM, conf=0.79)

    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 Folkersen et al, 2020

    The Results section on genome-wide meta-analysis reports pQTLs for 85 of 90 plasma proteins, and Online Methods describes the antibody-based Olink assay. The Results section on heritability reports substantial variation explained by genetic scores, but our copy does not substantiate the specific claim that pQTLs explain up to 30% of protein variance; it gives different summary figures. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Protein quantitative trait loci (pQTL) are commonly detected in large-scale studies.

    “Protein quantitative trait loci (pQTL), or associations between circulating protein abundances and genetic variants either within or nearby (cis-) to the protein-encoding gene or elsewhere in the genome (trans-), are commonly detected in large-scale studies1–6.”
  • Antibody-based genetic studies have focused on narrower collections of proteins at large scale or broad collections of proteins at smaller scale.

    “Antibody-based genetic studies have focused on narrower collections of proteins at large scale 22 or broad collections of proteins at smaller scale 23 .”
  • The use of covariate adjustment in the pQTL analyses follows standard procedures.

    “This use of covariate adjustment follows standard procedures (Folkersen et al, 2020) in pQTL analyses.”

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.
