Scene IV: Martha shares a secret

Martha tells the genetic counselor that she has just learned that she is about 6 weeks pregnant. At 40, she is concerned about her age-related risks of having a baby with a problem.

A discussion about multifactorial disorders such as cleft lip and palate follows, and a recurrence risk of about 4% is estimated.

Martha is reminded that if she has a boy, there is a 50% chance that he will have hemophilia.

“I don’t suppose that there’s any testing that can give me more information? By the way, you’d better not tell Stacy or David any of this, or I’ll sue you and this place…”
