Abstract

<abstract abstract-type="main"> <title> <x xml:space="preserve">Abstract</x> </title> <sec id="ajmga36340-sec-0001" sec-type="section"> <p>Shprintzen‐Goldberg syndrome (OMIM #182212) is a connective tissue disorder characterized by craniosynostosis, distinctive craniofacial features, skeletal abnormalities, marfanoid body habitus, aortic dilatation, and intellectual disability. Mutations in exon 1 of <italic>SKI</italic> have recently been identified as being responsible for approximately 90% of reported individuals diagnosed clinically with Shprintzen‐Goldberg syndrome. SKI is a known regulator of TGFβ signaling. Therefore, like Marfan syndrome and Loeys‐Dietz syndrome, Shprintzen‐Goldberg syndrome is likely caused by deregulated TGFβ signals, explaining the considerable phenotypic overlap between these three disorders. We describe two additional patients with exon 1 <italic>SKI</italic> mutations and review the clinical features and literature of Shprintzen‐Goldberg syndrome. © 2013 Wiley Periodicals, Inc.</p> </sec> </abstract>
