Loeys-Dietz Syndrome (LDS) is an autosomal dominant connective tissue disorder. The major hallmark of LDS is thoracic aortic aneurysm and dissection (TAAD). We generated an induced pluripotent stem cell (iPSC) line of a severely affected LDS patient carrying a pathogenic SMAD3 p.Arg287Gln variant. Peripheral blood mononuclear cells were reprogrammed using non-integrating Sendai viral vectors. The autonomous pluripotency state of the resulting iPSC model was proven by the presence of pluripotency markers, trilineage differentiation potential and absence of the Sendai vector backbone. This iPSC line can be used to study and/or therapeutically target the cellular pathomechanisms of SMAD3-related LDS., Competing Interests: Declaration of Competing Interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Joe Davis Velchev reports financial support was provided by Research Foundation Flanders., (Copyright © 2022 The Authors.

Loeys-Dietz syndrome (LDS) is an autosomal-dominant connective tissue disorder, commonly caused by genetic mutation of transforming growth factor-beta receptor (TGFBR)-1 or TGFBR2. This study describes the generation of human induced pluripotent stem cells (hiPSCs) from peripheral blood mononuclear cells obtained from an LDS patient with TGFBR2 mutation (R193W). Analysis confirmed the cells had a normal karyotype, expressed typical pluripotency markers, had the ability to differentiate into all three germ layers in vivo, and retained the TGFBR2 mutation from the derived hiPSCs. This iPSC line represents a potentially useful tool for investigating LDS disease mechanisms., (Copyright © 2017. Published by Elsevier B.V.)
