The Loeys-Dietz syndrome (LDS) is an autosomal dominant aortic aneurysm syndrome with widespread systemic involvement. As defined by Loeys et al. (2006), the disorder is characterized by the triad of arterial tortuosity and aneurysms, hypertelorism, and bifid uvula or cleft palate. Some patients have craniofacial involvement consisting of cleft palate, craniosynostosis, or hypertelorism. Bifid uvula may also be present.
