Generation of an induced pluripotent stem cell line from a patient with Loeys-Dietz syndrome

Loeys-Dietz syndrome (LDS) is a rare autosomal dominant connective tissue disorder caused by pathogenic variants in genes involved in the TGF-β signaling pathway. Here, we report the generation of a human induced pluripotent stem cell (iPSC) line derived from peripheral blood mononuclear cells (PBMCs) of an LDS patient carrying a heterozygous TGFBR1 mutation (c.679G > A, p.Glu227Lys). The iPSC line exhibits normal morphology, expresses pluripotency markers, maintains chromosomal integrity, and demonstrates trilineage differentiation capacity. This patient-specific iPSC line provides a valuable platform for modeling LDS pathogenesis and investigating vascular disease mechanisms.
