The genetic architecture of DED is largely unknown. Here, we develop and validate an algorithm for DED in the Million Veteran Program using a combination of diagnosis codes and prescription records, resulting in 132,657 cases and 352,201 controls. In a multi-ancestry genome-wide association study, we identify ten significant loci in nine susceptibility regions with largely consistent effects across ancestries, including loci linked to synapse maintenance (\n                  <jats:italic>EPHA5<\/jats:italic>\n                  ,\n                  <jats:italic>GRIA1<\/jats:italic>\n                  ,\n                  <jats:italic>SYNGAP1<\/jats:italic>\n                  ) and autoimmunity (\n                  <jats:italic>BLK<\/jats:italic>\n                  ). Phenome-wide scans for genetic pleiotropy indicate substantial genetic correlations of DED with comorbidities, including fibromyalgia, post-traumatic stress disorder, and Sj\u00f6gren\u2019s disease. Finally, applying genomic structural equation modeling, we derive a latent factor underlying DED and other chronic pain traits which accounts for 51% of the genetic variance of DED.\n                <\/jats:p>","DOI":"10.1101\/2025.03.18.25324218","type":"posted-content","created":{"date-parts":[[2025,3,23]],"date-time":"2025-03-23T01:43:52Z","timestamp":1742694232000},"source":"Crossref","is-referenced-by-count":1,"title":["Genome-wide association study of dry eye disease reveals shared heritability with systemic comorbidities"],"prefix":"10.64898","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4239-4672","authenticated-orcid":false,"given":"Bryan R.","family":"Gorman","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jaxon J.","family":"Huang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9321-657X","authenticated-orcid":false,"given":"Peter B.","family":"Barr","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christopher W.","family":"Halladay","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cari L.","family":"Nealon","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0557-9501","authenticated-orcid":false,"given":"Chris","family":"Chatzinakos","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1320-7161","authenticated-orcid":false,"given":"Michael","family":"Francis","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chen","family":"Jiang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Million Veteran","family":"Program","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2305-6766","authenticated-orcid":false,"given":"Paul B.","family":"Greenberg","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2834-2024","authenticated-orcid":false,"given":"Wen-Chih","family":"Wu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Saiju","family":"Pyarajan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9839-8667","authenticated-orcid":false,"given":"H\u00e9l\u00e8ne","family":"Choquet","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2215-5946","authenticated-orcid":false,"given":"Tim B.","family":"Bigdeli","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7488-250X","authenticated-orcid":false,"given":"Sudha K.","family":"Iyengar","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4419-7226","authenticated-orcid":false,"given":"Neal S.","family":"Peachey","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3026-6155","authenticated-orcid":false,"given":"Anat","family":"Galor","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"54368","reference":[{"key":"2025032403000520000_2025.03.18.25324218v1.1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jtos.2017.05.008"},{"key":"2025032403000520000_2025.03.18.25324218v1.2","doi-asserted-by":"crossref","first-page":"192","DOI":"10.1097\/ICL.0000000000000249","article-title":"Characteristics of Ocular Pain Complaints in Patients With Idiopathic Dry Eye Symptoms","volume":"43","year":"2017","journal-title":"Eye Contact Lens"},{"key":"2025032403000520000_2025.03.18.25324218v1.3","doi-asserted-by":"publisher","DOI":"10.1016\/j.jtos.2017.05.001"},{"key":"2025032403000520000_2025.03.18.25324218v1.4","doi-asserted-by":"crossref","first-page":"438","DOI":"10.1016\/j.jtos.2017.05.011","article-title":"TFOS DEWS II pathophysiology report","volume":"15","year":"2017","journal-title":"Ocul.
