These patients have craniofacial and skeletal features that overlap with the Marfan syndrome (MFS), and more importantly, have significant vascular fragility as is seen in MFS and Ehlers\u2013Danlos syndrome Type IV (EDS\u2010IV). The skeletal phenotype with respect to low bone mineral density and skeletal fragility is not clear. We present two patients with LDS with significant skeletal fragility. The first is a 17\u2010year\u2010old male who had talipes equinovarus, diaphragmatic and inguinal and herniae, aortic root dilatation necessitating surgical repair, craniofacial and skeletal dysmorphism consistent with LDS, and a history of numerous fragility fractures leading to significant skeletal deformity. He was found to be heterozygous for a c.923T\u2009&gt;\u2009C transition in exon 4 of <jats:italic>TGFBR2<\/jats:italic>. The second is a 26\u2010year\u2010old male with submucous cleft palate, talipes equinovarus, pectus excavatum requiring surgery, inguinal hernia, and aneurysms in the ascending aorta, abdominal aorta, carotid, subclavian, vertebral and brachial arteries requiring surgical repairs. He also had craniofacial and skeletal dysmorphism consistent with LDS, multiple fractures in childhood, low bone mineral density, and was found to be heterozygous for a c.1561 T\u2009&gt;\u2009C transition in exon 7 of <jats:italic>TGFBR2<\/jats:italic>. These case studies highlight the importance of paying close attention to fractures and bone density in patients with LDS. Osteopenia or osteoporosis may become increasingly important issues as earlier detection and treatment of the vascular complications of LDS improves life expectancy in these patients. \u00a9 2010 Wiley\u2010Liss, Inc.<\/jats:p>","DOI":"10.1002\/ajmg.a.33356","type":"journal-article","created":{"date-parts":[[2010,3,26]],"date-time":"2010-03-26T18:24:59Z","timestamp":1269627899000},"page":"1016-1019","source":"Crossref","is-referenced-by-count":43,"title":["Germline TGF\u2010\u03b2 receptor mutations and skeletal fragility: A report on two patients with Loeys\u2013Dietz syndrome"],"prefix":"10.1002","volume":"152A","author":[{"given":"Salman","family":"Kirmani","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter J.","family":"Tebben","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aida N.","family":"Lteif","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David","family":"Gordon","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bart L.","family":"Clarke","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Theresa E.","family":"Hefferan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael J.","family":"Yaszemski","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pamela S.","family":"McGrann","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Noralane M.","family":"Lindor","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jay W.","family":"Ellison","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2010,3,26]]},"reference":[{"key":"e_1_2_5_2_1","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.0507417102"},{"key":"e_1_2_5_3_1","doi-asserted-by":"publisher","DOI":"10.1359\/jbmr.2001.16.10.1754"},{"key":"e_1_2_5_4_1","first-page":"307","article-title":"Bone mineral density in adults with marfan syndrome","volume":"39","author":"Carter N","year":"2000","journal-title":"Baillieres Clin Rheumatol"},{"key":"e_1_2_5_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/S8756-3282(98)00078-7"},{"key":"e_1_2_5_6_1","doi-asserted-by":"publisher","DOI":"10.1038\/81563"},{"key":"e_1_2_5_7_1","doi-asserted-by":"publisher","DOI":"10.1038\/79128"},{"key":"e_1_2_5_8_1","doi-asserted-by":"publisher","DOI":"10.1007\/s001980050257"},{"key":"e_1_2_5_9_1","doi-asserted-by":"publisher","DOI":"10.1038\/ng1511"},{"key":"e_1_2_5_10_1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa055695"},{"key":"e_1_2_5_11_1","doi-asserted-by":"publisher","DOI":"10.1038\/ng1392"},{"key":"e_1_2_5_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jbspin.2006.01.026"},{"key":"e_1_2_5_13_1","doi-asserted-by":"publisher","DOI":"10.1038\/ng1116"}],"container-title":["American Journal of Medical Genetics Part A"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Fajmg.a.33356","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/ajmg.a.33356","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,18]],"date-time":"2023-10-18T14:23:20Z","timestamp":1697639000000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/ajmg.a.33356"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2010,3,26]]},"references-count":12,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2010,4]]}},"alternative-id":["10.1002\/ajmg.a.33356"],"URL":"https:\/\/doi.org\/10.1002\/ajmg.a.33356","archive":["Portico"],"relation":{},"ISSN":["1552-4825","1552-4833"],"issn-type":[{"value":"1552-4825","type":"print"},{"value":"1552-4833","type":"electronic"}],"subject":[],"published":{"date-parts":[[2010,3,26]]}}}
