WebDec 20, 2024 · Explanation: Classical PKU is an autosomal recessive disorder, caused by mutations in both alleles of the gene for phenylalanine hydroxylase (PAH), found on chromosome 12. In the body, phenylalanine hydroxylase converts the amino acid phenylalanine to tyrosine, another amino acid. Advertisement. WebPhenylketonuria (PKU) is an autosomal recessive disease with important consequences on nervous system development, if not properly treated. Decrease of the antioxidative mechanisms, altered transport of amino acids through the blood-brain barrier,
WebSpecial enzymes then make changes to the amino acids so the body can use them. PKU occurs when an enzyme, called “ phenylalanine hydroxylase” (PAH), is either missing or not working properly. The job of this enzyme is to chemically change the amino acid phenylalanine (Phe – pronounced ‘fee’) into other substances. WebPhenylketonuria is an example of a genetic disease in which a. a single enzyme is not functional. b. inheritance is sex-linked. c. Two parents without the disease cannot have a child with the disease. d. mental retardation always occurs, regardless of treatment. e. a transport protein does not work properly..
