How likely is ehlers-danlos syndrome if one parent has some characteristics of it?

From 0 to 50%: Ehlers-danlos syndrome (eds) is a group of inheritable disorders. There are two different inheritance patterns of eds, autosomal dominant and autosomal recessive. If you have the dominant type, there's a 50% risk of eds in your child. If you have the recessive type, eds can only occur if your partner also carries the recessive gene. A genetic counselor is needed to tell you your exact risk.
