An autosomal dominant trait is discovered by a nurse constructing a client pedigree. The trait has not appeared in two generations but was strongly evident three generations ago. What advice should the nurse provide for the client?
1. "Your family should be genetically tested for this trait."
2. "The men in your family should be genetically tested for this trait."
3. "This trait existed in your past, but will not be transmitted now."
4. "Your children have a 25% risk of inheriting this trait."
3
Rationale 1: The trait will not be expressed in current generations of this family line.
Rationale 2: There is no evidence that there is a difference between the risk for the men and the risk for the women in the family.
Rationale 3: Once the trait does not affect a generation, the transmission ends.
Rationale 4: The transmission possibility for autosomal dominant traits is 50%.
