One cohort was for discovery and the other for replication. The discovery case\u2013control analysis utilized anonymized DNA samples and evaluated 1,614 single-nucleotide polymorphisms (SNPs) in 145 genes concentrated in inflammation, angiogenesis, brain development, and oxidation pathways. Cases were children who died by age one or who were diagnosed with cerebral palsy (CP) or neurodevelopmental delay (Bayley II mental developmental index [MDI] or psychomotor developmental index [PDI]\u2009&lt;\u200970) by 18 to 22 months. Controls were survivors with normal neurodevelopment. We assessed significant epidemiological variables and SNPs associated with the combined outcome of CP or death, CP, mental delay (MDI\u2009&lt;\u200970) and motor delay (PDI\u2009&lt;\u200970). Multivariable analyses adjusted for gestational age at birth, small for gestational age, sex, antenatal corticosteroids, multiple gestation, racial admixture, and multiple comparisons. SNPs associated with adverse neurodevelopmental outcomes with p\u2009&lt;\u20090.01 were selected for validation in the replication cohort.

After adjusting for covariates, 26 SNPs with p\u2009&lt;\u20090.01 for one or more outcomes were selected for replication cohort validation, which included 362 infants (170 cases and 192 controls). A variant in SERPINE1, which encodes plasminogen activator inhibitor (PAI1), was associated with the combined outcome of CP or death in the discovery analysis (p\u2009=\u20094.1\u2009\u00d7\u200910\u22124) and was significantly associated with CP or death in the replication cohort (adjusted odd ratio: 0.4; 95% confidence interval: 0.2\u20131.0; p\u2009=\u20090.039).<\/jats:p><jats:p>\n            Conclusion\u2003A genetic variant in SERPINE1, involved in inflammation and coagulation, is associated with CP or death among ELBW infants.<\/jats:p><jats:p>\n            Key Points\n          <\/jats:p>","DOI":"10.1055\/s-0043-1774312","type":"journal-article","created":{"date-parts":[[2023,9,19]],"date-time":"2023-09-19T22:52:25Z","timestamp":1695163945000},"page":"e2710-e2716","source":"Crossref","is-referenced-by-count":0,"special_numbering":"S","title":["Genetic Predisposition to Adverse Neurodevelopmental Outcome of Extremely Low Birth Weight Infants"],"prefix":"10.1055","volume":"41","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9455-3973","authenticated-orcid":false,"given":"Michael W.","family":"Varner","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, University of Utah, Salt Lake City, Utah"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elizabeth A.","family":"Thom","sequence":"additional","affiliation":[{"name":"Biostatistics Coordinating Center, George Washington University, Washington, District of Columbia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C.
