Multiple Choice

A 31-year-old man has been diagnosed with chronic obstructive pulmonary disease (COPD) as a result of being homozygous for the ZZ mutation of the alpha1-antitrypsin (AAT) gene alleles.His wife has been tested and does not have a mutation of her AAT gene alleles.The man is worried that his three children may eventually develop COPD.What is your best response?

• A)"Because your wife does not have the mutation and neither of your parents have the disease,your children will not be affected."
• B)"Because your wife is not affected nor is a carrier,your children will have normal levels of AAT and their risk is the same as for the general population."
• C)"Because you have the mutations and your wife does not,your son will be at an increased risk for developing COPD but your daughter will only be a carrier."
