What is the difference between Marfan and Loeys-Dietz syndrome?

Typically in Marfan syndrome surgery is considered when the aorta is around 5 cm; however, in Loeys-Dietz syndrome it has been recognized that individuals with aortic root measurements of 4 cm have shown aortic root dissection (in teens/adults).
