Here, we report that the thrombocytopenia-, myelodysplastic syndromes-, and leukemia-associated P214L mutation in the transcriptional regulator ETV6 creates an XPO1-dependent nuclear export signal to cause protein mislocalization. Strategies to disrupt XPO1 activity fully restore ETV6 P214L protein nuclear localization and transcription regulation activity. Mechanistic insight inspired the design of a \u2018humanized\u2019 ETV6 mice, which we employ to demonstrate that the germline P214L mutation is sufficient to elicit severe defects in thrombopoiesis and hematopoietic stem cell maintenance. Beyond ETV6, we employed computational methods to uncover rare disease-associated missense mutations in unrelated proteins that create a nuclear export signal to disrupt protein function. Thus, missense mutations that operate through this mechanism should be predictable and may suggest rational therapeutic strategies for associated diseases.<\/jats:p>","DOI":"10.1101\/2024.04.24.590854","type":"posted-content","created":{"date-parts":[[2024,4,24]],"date-time":"2024-04-24T23:45:20Z","timestamp":1714002320000},"source":"Crossref","is-referenced-by-count":1,"title":["Enigmatic missense mutations can cause disease via creation of\n                  <i>de novo<\/i>\n                  nuclear export signals"],"prefix":"10.64898","author":[{"given":"By Michael","family":"McConville","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Toby","family":"Thomas","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ryan","family":"Beckner","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Catherine","family":"Valadez","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"YuhMin","family":"Chook","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stephen","family":"Chung","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8194-5281","authenticated-orcid":false,"given":"Glen","family":"Liszczak","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"54368","reference":[{"key":"2024042623301267000_2024.04.24.590854v1.1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pcbi.1002709"},{"key":"2024042623301267000_2024.04.24.590854v1.2","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pcbi.1009911"},{"key":"2024042623301267000_2024.04.24.590854v1.3","doi-asserted-by":"publisher","DOI":"10.1038\/s41586-019-1879-7"},{"key":"2024042623301267000_2024.04.24.590854v1.4","doi-asserted-by":"publisher","DOI":"10.1101\/gad.1239604"},{"key":"2024042623301267000_2024.04.24.590854v1.5","doi-asserted-by":"publisher","DOI":"10.1101\/gad.12.15.2392"},{"key":"2024042623301267000_2024.04.24.590854v1.6","doi-asserted-by":"publisher","DOI":"10.1038\/sj.onc.1208588"},{"key":"2024042623301267000_2024.04.24.590854v1.7","doi-asserted-by":"publisher","DOI":"10.1084\/jem.20112239"},{"key":"2024042623301267000_2024.04.24.590854v1.8","doi-asserted-by":"publisher","DOI":"10.1038\/nature10725"},{"key":"2024042623301267000_2024.04.24.590854v1.9","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa1013343"},{"key":"2024042623301267000_2024.04.24.590854v1.10","doi-asserted-by":"publisher","DOI":"10.1002\/gcc.2870090307"},{"key":"2024042623301267000_2024.04.24.590854v1.11","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa1403088"},{"key":"2024042623301267000_2024.04.24.590854v1.12","doi-asserted-by":"publisher","DOI":"10.1016\/0092-8674(94)90322-0"},{"key":"2024042623301267000_2024.04.24.590854v1.13","doi-asserted-by":"publisher","DOI":"10.1016\/j.leukres.2012.04.010"},{"key":"2024042623301267000_2024.04.24.590854v1.14","doi-asserted-by":"publisher","DOI":"10.1016\/j.cell.2012.06.023"},{"key":"2024042623301267000_2024.04.24.590854v1.15","doi-asserted-by":"publisher","DOI":"10.1038\/leu.2013.58"},{"key":"2024042623301267000_2024.04.24.590854v1.16","doi-asserted-by":"publisher","DOI":"10.1038\/ng.3253"},{"key":"2024042623301267000_2024.04.24.590854v1.17","doi-asserted-by":"crossref","unstructured":"Topka, S. et al.
