ABSTRACT
Loeys-Dietz syndrome (LDS) is a rare connective tissue disorder characterized by a genetic predisposition for thoracic aortic aneurysm and dissection. Despite heterozygous loss-of-function mutations in genes for ligand, receptor, or downstream mediators of the transforming growth factor ß (TGFß) pathway, LDS is associated with a signature of high TGFß signaling. We generated induced pluripotent stem cell (iPSC) lines from three adult LDS-patients (two male, one female) of a family with a heterozygous point mutation in exon 4 of the TGFß-receptor1 (TGFBR1) gene (p.M253I; c.759G>A). The lines offer a valuable resource for modeling the pathophysiology of genetically mediated aortic disease.
