Genetic instruments for pQTLs were obtained from five proteomic studies. Bayesian colocalization analysis and summary-data-based MR (SMR) analysis were performed to assess the causal relationship between two related signals (protein levels and PE risk). We further conducted single-cell type expression analysis and phenome-wide MR. In addition, a protein\u2013protein interaction network of key genes was constructed\n                      <jats:italic toggle=\"yes\">via<\/jats:italic>\n                      the GeneMANIA website.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      At a significance level of\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      &lt; 5 \u00d7 10\n                      <jats:sup>\u22128<\/jats:sup>\n                      , MR analysis revealed seven protein-PE pairs. Gene prediction indicated that KDEL (Lys-Asp-Glu-Leu) Containing 2 and Keratin 18 (KRT18) were positively correlated with the risk of PE, whereas the other five proteins (Complement Factor B [CFB], FYN Proto-Oncogene [FYN], RAN Binding Protein 1 [RANBP1], Amphoterin-Induced Gene and ORF 1 [AMIGO1], and Arginase 2 [ARG2]) were negatively correlated. None of the five proteins had reverse causality. Bayesian colocalization analysis verified the positive correlation of CFB (coloc.coloc.susie PPH4 = 1) and KRT18 (coloc.coloc.abf PPH4 = 0.74) with PE.
