EBF3 is a gene with an excess of protein-coding de novo variants and underlies Hypotonia, Ataxia, and Delayed Development Syndrome. We previously identified noncoding de novo variants in an enhancer of EBF3 and further found enrichment of deletions of this enhancer in NDDs. In this study, we generated a novel mouse line that deletes the highly conserved, orthologous mouse region within the Rr169617 regulatory region, and characterized the molecular and phenotypic aspects of this mouse model. We found a deviation from Mendelian expectation (P=0.02) with significant depletion of the deletion allele (P=5.8\u00d710\u22124). Rr169617+\/\u2212 mice had a reduction of Ebf3 expression by 10% and Rr169617\u2212\/\u2212 mice had a reduction by 20%. Differential expression analyses in E12.5 forebrain, midbrain, and hindbrain in Rr169617+\/+ versus Rr169617\u2212\/\u2212 mice identified dysregulated genes including histone and brain development related genes. A priori phenotyping analysis (open field, hole board and light\/dark transition) identified sex-specific differences in mobility only for Rr169617\u2212\/\u2212 mice across multiple behavioral assays with Rr169617\u2212\/\u2212 males less mobile than Rr169617\u2212\/\u2212 females. Furthermore, both sexes when homozygous for the enhancer deletion displayed body composition differences when compared to wildtype mice. Overall, we show that deletion within Rr169617 reduces expression of Ebf3 and results in phenotypic outcomes consistent with potential sex specific behavioral differences.<\/jats:p>","DOI":"10.1242\/bio.062070","type":"journal-article","created":{"date-parts":[[2025,10,13]],"date-time":"2025-10-13T12:03:54Z","timestamp":1760357034000},"source":"Crossref","is-referenced-by-count":4,"title":["Generation and characterization of a knockout mouse of an enhancer of\n                    <i>EBF3<\/i>"],"prefix":"10.1242","volume":"14","author":[{"given":"Emily","family":"Cordova Hurtado","sequence":"first","affiliation":[{"name":"Washington University School of Medicine 1 Department of Genetics , , St. Louis, MO 63110 ,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Janine M.","family":"Wotton","sequence":"additional","affiliation":[{"name":"The Jackson Laboratory 2 , Bar Harbor, ME 04609 ,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alexander","family":"Gulka","sequence":"additional","affiliation":[{"name":"Emory University 3 Department of Biology , , Atlanta, GA 30322 ,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Crystal","family":"Burke","sequence":"additional","affiliation":[{"name":"The Jackson Laboratory 2 , Bar Harbor, ME 04609 ,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeffrey K.","family":"Ng","sequence":"additional","affiliation":[{"name":"Washington University School of Medicine 1 Department of Genetics , , St. Louis, MO 63110 ,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ibrahim","family":"Bah","sequence":"additional","affiliation":[{"name":"Washington University School of Medicine 1 Department of Genetics , , St. Louis, MO 63110 ,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juana","family":"Manuel","sequence":"additional","affiliation":[{"name":"Washington University School of Medicine 1 Department of Genetics , , St. Louis, MO 63110 ,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hillary","family":"Heins","sequence":"additional","affiliation":[{"name":"Washington University School of Medicine 1 Department of Genetics , , St. Louis, MO 63110 ,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephen A.","family":"Murray","sequence":"additional","affiliation":[{"name":"The Jackson Laboratory 2 , Bar Harbor, ME 04609 ,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David U.","family":"Gorkin","sequence":"additional","affiliation":[{"name":"Emory University 3 Department of Biology , , Atlanta, GA 30322 ,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jacqueline K.","family":"White","sequence":"additional","affiliation":[{"name":"The Jackson Laboratory 2 , Bar Harbor, ME 04609 ,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kevin A.","family":"Peterson","sequence":"additional","affiliation":[{"name":"The Jackson Laboratory 2 , Bar Harbor, ME 04609 ,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8246-6477","authenticated-orcid":false,"given":"Tychele N.","family":"Turner","sequence":"additional","affiliation":[{"name":"Washington University School of Medicine 1 Department of Genetics , , St. Louis, MO 63110 ,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"237","published-online":{"date-parts":[[2025,11,7]]},"reference":[{"key":"2026022504571976100_BIO062070C1","doi-asserted-by":"publisher","first-page":"eaat6576","DOI":"10.1126\/science.aat6576","article-title":"Genome-wide de novo risk score implicates promoter variation in autism spectrum disorder","volume":"362","author":"An","year":"2018","journal-title":"Science"},{"key":"2026022504571976100_BIO062070C2","doi-asserted-by":"publisher","first-page":"1035","DOI":"10.1001\/jamapsychiatry.2019.1411","article-title":"Association of genetic and environmental factors with autism in a 5-country cohort","volume":"76","author":"Bai","year":"2019","journal-title":"JAMA Psychiatry"},{"key":"2026022504571976100_BIO062070C3","doi-asserted-by":"publisher","first-page":"667","DOI":"10.1016\/j.ajhg.2016.02.018","article-title":"Frequency and complexity of De Novo structural mutation in autism","volume":"98","author":"Brandler","year":"2016","journal-title":"Am.
