(2004); Nat Genet 36:855\u2013860] and of <jats:italic>TGFBR1<\/jats:italic> and <jats:italic>TGFBR2<\/jats:italic> mutations in Loeys\u2013Dietz aortic aneurysm syndrome (LDS) [Loeys et al. (2005); Nat Genet 37:275\u2013281] [OMIM 609192] has provided direct evidence of abnormal signaling in transforming growth factors \u03b2 (TGF\u2010\u03b2) in the pathogenesis of Marfan syndrome (MFS). In light of this, we describe the phenotypes and genotypes of five individuals. Patient 1 had MFS and abnormal cranial dura. Patient 2 had severe early onset MFS and an abnormal skull. Patients 3 and 4 had probable Furlong syndrome (FS). Patient 5 had marfanoid (MD) features, mental retardation (MR), and a deletion of chromosome 15q21.1q21.3. All patients had a condition within the MFS, MD\u2010craniosynostosis (CS) or MD\u2010MR spectrum. The names of these entities may become redundant, and instead, come to be considered within the spectrum of TGF\u2010\u03b2 signaling pathway disorders. Two recurrent heterozygous <jats:italic>FBN1<\/jats:italic> mutations were found in Patients 1 and 2, and an identical novel heterozygous de novo <jats:italic>TGFBR1<\/jats:italic> mutation was found in Patients 3 and 4, in whom altered fibrillin\u20101 processing was demonstrated previously [Milewicz et al. (2000); Am J Hum Genet 67:279]. A heterozygous <jats:italic>FBN1<\/jats:italic> deletion was found in Patient 5. These findings support the notion that perturbation of extracellular matrix homeostasis and\/or remodeling caused by abnormal TGF\u2010\u03b2 signaling is the core pathogenetic mechanism in MFS and related entities including the MD\u2010CS syndromes. \u00a9 2006 Wiley\u2010Liss, Inc.<\/jats:p>","DOI":"10.1002\/ajmg.a.31202","type":"journal-article","created":{"date-parts":[[2006,4,5]],"date-time":"2006-04-05T03:16:35Z","timestamp":1144206995000},"page":"1047-1058","source":"Crossref","is-referenced-by-count":73,"title":["<i>FBN1<\/i>, <i>TGFBR1<\/i>, and the Marfan\u2010craniosynostosis\/mental retardation disorders revisited"],"prefix":"10.1002","volume":"140A","author":[{"given":"L.C.","family":"Ad\u00e8s","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"K.","family":"Sullivan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.","family":"Biggin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"E.A.","family":"Haan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.","family":"Brett","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"K.J.","family":"Holman","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.","family":"Dixon","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S.","family":"Robertson","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.D.","family":"Holmes","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.","family":"Rogers","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"B.","family":"Bennetts","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2006,4,4]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1002\/ajmg.1320570410"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/ajmg.10333"},{"key":"e_1_2_6_4_1","unstructured":"Ad\u00e8sLC BigginA HolmanK BrettM SullivanK BennettsB.2005.FBN1 TGFBR1andTGFBR2gene screening in Shprintzen\u2010Goldberg syndrome and inFBN1mutation\u2010negative Marfan syndrome.
