The chances of a person with this disease passing the disease to their child

If you are affected with Marfan Syndrome you have a 50% chance of passing the affected trait to your children.  Meaning if Mike is affected with Marfan Syndrome than his son, Will, has a 50% chance of getting Marfan Syndrome.  Women and men are affected alike, this trait is not x-linked.
