My father has protein c and s deficiency (genetic disorder), my mother doesnt. i have never tested to see if i have it as well, only did twice a d-dimer test and it was normal. would i have chances to have protein c and s deficiency?

There are 2 ways to inherit either S or C deficiency. A milder form of both would be inherited as an autosomal dominant, with 50% of offspring affected. The more severe form is found when a person gets a defective gene for either S or C from both parents, with 25% risk when both parents carry the gene. Share your concerns with your doc & decide based on the extra information you both have.
