Question

Quizplus · Accepted Answer

The genetic code given refers to the different alleles and their mutations of the alpha-1 antitrypsin (A1AT) gene. The MM genotype refers to a person with two copies of the normal A1AT gene. The Z phenotype and ZZ genotype refer to a mutated form of the gene that can lead to deficiency in A1AT production and potential lung disease. The MZ genotype refers to a person with one normal and one mutated gene, which may increase the risk of lung disease but is not as severe as the ZZ genotype. The code given does not indicate any mutations, therefore the person has a normal level of A1AT and the genotype is MM.
