Loeys-Dietz syndrome: 2026 updated care management primer

Loeys-Dietz syndrome (LDS) represents a clinically and genetically heterogeneous group of connective tissue disorders that share features similar to Marfan syndrome, first identified in 2005. Characterized by significant manifestations, such as aortic aneurysms, arterial tortuosity, craniofacial and skeletal anomalies, LDS results from pathogenic variants in key genes of the transforming growth factor-beta signaling pathway. Given its variable expressivity, a multidisciplinary approach to management is critical.
