A couple has given birth to their first child, a boy with a recessive disorder. The genetic counselor tells them that the risk of recurrence is one in four. Which statement is a correct interpretation of this information?
a. The risk factor remains the same for each pregnancy.
b. The risk factor will change when they have a second child.
c. Because the parents have one affected child, the next three children should be unaffected.
d. Because the parents have one affected child, the next child is four times more likely to be affected.
ANS: A
Each pregnancy has the same risks for an affected child. Because an odds ratio reflects the risk, this does not change over time. The statement by the genetic counselor refers to a probability. This does not change over time. The statement "Because the parents have one affected child, the next child is four times more likely to be affected" does not reflect autosomal recessive inheritance.
