Loeys-Dietz syndrome (LDS)
Loeys-Dietz syndrome (LDS) is an autosomal dominant disorder characterized by arterial aneurysms and dissections, pectus excavatum, craniosynostosis, cleft palate, congenital heart disease, and thin, translucent skin. LDS results from mutations in the TGF beta receptor genes.  LDS has been subdivided in LDS1 and LDS2 on the basis of the presence or the absence of craniofacial involvement, respectively. LDS3 is associated with early-onset osteoarthritis and caused by mutation in the SMAD3 gene. LDS4 is caused by mutation in the TGFB2 gene.
