Here we evaluate the genetic factors influencing the humoral immune response to EBV and establish a polygenic risk score (PRS) for anti-EBNA1 responses.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We conducted a multi-biobank genetic study for the serologic humoral IgG antibody response to EBV-EBNA1, including data from the UK Biobank (UKB, N = 9695 individuals) and the Milieu Int\u00e9rieur (MI) cohort from Institute Pasteur (IP) (N = 1000), as well as GWAS summary statistics for individuals of African ancestry (N = 4365). We divided the cohort into discovery and validation, performed GWAS analyses, and developed a PRS using a Bayesian multi-ancestry approach application (PRS-CSx). After successfully validating PRS predictive performance, we then applied PheWAS analyses to all UKB datasets.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Consistent with a previous report, our GWAS analyses identified an association at chromosome 6 within the MHC region as the most significant SNP (rs6927022; p = 8.21 \u00d7 10\n                      <jats:sup>\u2212113<\/jats:sup>\n                      ). Meta-analyses of all cohorts identified several regions outside of the MHC region with the strongest effects at 10p12 within the armadillo repeat containing three gene (\n                      <jats:italic>ARMC3<\/jats:italic>\n                      ) (rs10763372; p = 9.93 \u00d7 10\n                      <jats:sup>\u221208<\/jats:sup>\n                      ) and at 10q22 upstream of Neuregulin-3 (\n                      <jats:italic>NRG3<\/jats:italic>\n                      ) (rs61851627; p = 8.62 \u00d7 10\n                      <jats:sup>\u22129<\/jats:sup>\n                      ). A multi-ancestry PRS model was then trained and developed, obtaining successful predictive performance in validation cohorts (AUC ranges from 65% to 72%). Finally, PheWAS analyses using the developed PRS confirmed a significant positive association with multiple sclerosis (p = 1.14 \u00d7 10\n                      <jats:sup>\u221210<\/jats:sup>\n                      ), and also identified novel negative associations with other spectra of autoimmune disease, including Celiac disease (2.03 \u00d7 10\n                      <jats:sup>\u2212127<\/jats:sup>\n                      ).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>We developed and validated a multi-ancestry PRS for EBNA1 IgG response that enables genetic profiling of EBV antibody responsiveness in genotyped cohorts lacking serologic measurements. PheWAS results support shared and divergent genetic relationships between EBV antibody response and autoimmune disease, motivating mechanistic and longitudinal follow-up studies. Further research is needed to evaluate the future implementation of this PRS in the clinic to improve long-term health outcomes.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3389\/fgene.2026.1786510","type":"journal-article","created":{"date-parts":[[2026,3,15]],"date-time":"2026-03-15T22:10:12Z","timestamp":1773612612000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":1,"title":["Polygenic risk score and phenome-wide association study of the Epstein-Barr virus antibody response"],"prefix":"10.3389","volume":"17","author":[{"given":"Bahram","family":"Namjou","sequence":"first","affiliation":[{"name":"Center for Autoimmune Genomics and Etiology, Cincinnati Children\u2019s Hospital Medical Center","place":["Cincinnati, OH, United States"]},{"name":"Department of Pediatrics, University of Cincinnati College of Medicine","place":["Cincinnati, OH, United States"]},{"name":"Division of Human Genetics, Cincinnati Children\u2019s Hospital Medical Center","place":["Cincinnati, OH, United States"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael","family":"Lape","sequence":"additional","affiliation":[{"name":"Center for Autoimmune Genomics and Etiology, Cincinnati Children\u2019s Hospital Medical Center","place":["Cincinnati, OH, United States"]},{"name":"Department of Biomedical Informatics, University of Cincinnati College of Medicine","place":["Cincinnati, OH, United States"]},{"name":"Division of Allergy & Immunology, Cincinnati Children\u2019s Hospital Medical Center","place":["Cincinnati, OH, United States"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthew T.","family":"Weirauch","sequence":"additional","affiliation":[{"name":"Center for Autoimmune Genomics and Etiology, Cincinnati Children\u2019s Hospital Medical Center","place":["Cincinnati, OH, United States"]},{"name":"Department of Pediatrics, University of Cincinnati College of Medicine","place":["Cincinnati, OH, United States"]},{"name":"Division of Human Genetics, Cincinnati Children\u2019s Hospital Medical Center","place":["Cincinnati, OH, United States"]},{"name":"Division of Biomedical Informatics, Cincinnati Children\u2019s Hospital Medical Center","place":["Cincinnati, OH, United States"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kenneth M.","family":"Kaufman","sequence":"additional","affiliation":[{"name":"Center for Autoimmune Genomics and Etiology, Cincinnati Children\u2019s Hospital Medical Center","place":["Cincinnati, OH, United States"]},{"name":"Department of Pediatrics, University of Cincinnati College of Medicine","place":["Cincinnati, OH, United States"]},{"name":"Division of Human Genetics, Cincinnati Children\u2019s Hospital Medical Center","place":["Cincinnati, OH, United States"]},{"name":"US Department of Veterans Affairs Medical Center","place":["Cincinnati, OH, United States"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Leah C.","family":"Kottyan","sequence":"additional","affiliation":[{"name":"Center for Autoimmune Genomics and Etiology, Cincinnati Children\u2019s Hospital Medical Center","place":["Cincinnati, OH, United States"]},{"name":"Department of Pediatrics, University of Cincinnati College of Medicine","place":["Cincinnati, OH, United States"]},{"name":"Division of Human Genetics, Cincinnati Children\u2019s Hospital Medical Center","place":["Cincinnati, OH, United States"]},{"name":"Division of Allergy & Immunology, Cincinnati Children\u2019s Hospital Medical Center","place":["Cincinnati, OH, United States"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,3,16]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"1121","DOI":"10.1086\/597424","article-title":"Strong correlations of anti-viral capsid antigen antibody levels in first-degree relatives from families with Epstein-Barr virus-related lymphomas","volume":"199","author":"Besson","year":"2009","journal-title":"J.
