Question

Consider the below scenario to answer questions 38-41. In a certain population, there's an autosomal recessive disorder called Phenylketonuria (PKU), characterized by the inability to metabolize the amino acid phenylalanine. The mutation responsible for PKU occurs in the gene PAH. While PKU is rare in the general population, it's relatively common in certain ethnic groups, such as those with Northern European ancestry. A 28-year-old woman named Emily, whose grandfather and maternal uncle has PKU, is concerned about the likelihood of having an affected child with her 30-year-old husband, Jack. Jack's family history is negative for PKU.
