Loeys-Dietz syndrome 1 (LDS1; MIM 609192) and 2 (LDS2; MIM 610168) are caused by mutations in the TGFBR1 and TGFBR2 genes respectively. The reported phenotype is highly variable and overlaps considerably with Ehlers-Danlos syndrome IV (EDS IV; MIM 130050) or Marfan syndrome (MFS; MIM 154700). A high percentage of patients have aortic root aneurysm or other arterial aneurysms.read more
