Bent Bone Dysplasia (BBD),\n FGFR2<\/jats:italic>\n \u2010related (MIM# 614592), is a rare severe skeletal dysplasia characterized by craniofacial differences, reduced bone mineral density, and bowed long bones. Only 14 individuals have been reported, of which the majority died prenatally or neonatally. We report the clinical trajectory of a 4\u2010year\u2010old male with BBD,\n FGFR2<\/jats:italic>\n \u2010related (\n FGFR2<\/jats:italic>\n , c.1141T>G), who initially presented neonatally with respiratory insufficiency requiring intubation, facial dysmorphism, and skeletal differences. He is able to walk, is interactive, has a tracheostomy for mechanical ventilation at night and a gastrostomy tube, and continues to make steady developmental progress. He is currently the longest reported living individual and with BBD,\n FGFR2<\/jats:italic>\n \u2010related in the literature to date. Our findings suggest that BBD,\n FGFR2<\/jats:italic>\n \u2010related is not definitively lethal perinatally. While the risk for complications and early postnatal death remains high, as demonstrated in previous literature, survival beyond the early postnatal period is possible. This report broadens the known postnatal developmental and medical trajectory of BBD,\n FGFR2<\/jats:italic>\n \u2010related, which is crucial for providing comprehensive genetic counseling.\n <\/jats:p>","DOI":"10.1002\/ajmg.a.64295","type":"journal-article","created":{"date-parts":[[2025,11,4]],"date-time":"2025-11-04T16:04:17Z","timestamp":1762272257000},"page":"728-732","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Clinical Presentation of the Longest Reported Living Individual With Bent Bone Dysplasia\u2014\n FGFR2<\/i>\n \u2010Related"],"prefix":"10.1002","volume":"200","author":[{"given":"Cheyenne","family":"Bates","sequence":"first","affiliation":[{"name":"Department of Pediatrics and Child Health University of Manitoba Winnipeg Manitoba Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pardeep","family":"Gill","sequence":"additional","affiliation":[{"name":"Department of Family Medicine McMaster University Hamilton Ontario Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthew","family":"Choi","sequence":"additional","affiliation":[{"name":"Division of Plastic Surgery, Department of Surgery McMaster University Hamilton Ontario Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Frances","family":"Mahon","sequence":"additional","affiliation":[{"name":"Division of General Pediatrics, Department of Pediatrics McMaster Children's Hospital Hamilton Ontario Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Blake","family":"Yarascavitch","sequence":"additional","affiliation":[{"name":"Division of Neurosurgery, Department of Surgery McMaster University Hamilton Ontario Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Audrey","family":"Lim","sequence":"additional","affiliation":[{"name":"Division of General Pediatrics, Department of Pediatrics McMaster Children's Hospital Hamilton Ontario Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3958-1653","authenticated-orcid":false,"given":"Resham","family":"Ejaz","sequence":"additional","affiliation":[{"name":"Division of Genetics, Department of Pediatrics McMaster Children's Hospital Hamilton Ontario Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,11,4]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00247\u2010015\u20103465\u2010y"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/ajmg.a.37772"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajhg.2012.02.005"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1002\/mgg3.1412"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1097\/mcd.0000000000000022"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1002\/ajmg.a.37473"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1002\/ajmg.a.63132"}],"container-title":["American Journal of Medical Genetics Part A"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/ajmg.a.64295","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1002\/ajmg.a.64295","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/ajmg.a.64295","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,2,14]],"date-time":"2026-02-14T21:14:56Z","timestamp":1771103696000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/ajmg.a.64295"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,11,4]]},"references-count":7,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2026,3]]}},"alternative-id":["10.1002\/ajmg.a.64295"],"URL":"https:\/\/doi.org\/10.1002\/ajmg.a.64295","archive":["Portico"],"relation":{},"ISSN":["1552-4825","1552-4833"],"issn-type":[{"value":"1552-4825","type":"print"},{"value":"1552-4833","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,11,4]]},"assertion":[{"value":"2025-07-04","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-10-24","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-11-04","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
