How do people inherit ehlers-danlos syndrome, vascular type?

Autosomal dominant. Eds vascular type or eds type IV is inherited in a autosomal dominant manner. That is any person that is affected has a 50% chance of passing on the disorder. For someone newly diagnosed, either one of their parents has the disorder (and they had a 50% chance of inheriting the gene) or that individual is a brand new genetic mutation and the first affected with a 50% of passing it to their childr.
Not well known. The inheritance pattern is variable. In the more common eds type3 (hypermobility type), the inheritance is autosomal dominant meaning 50% of offspring would be expected to have it. Rarer forms like the vascular type is less predictable. If you have a parent who died of aortic dissection, you should be checked yourself with an echocardiogram.
