Phenylketonuria (PKU) is caused by mutations in the PAH gene, which provides instructions for making an enzyme called phenylalanine hydroxylase. This enzyme is essential for the breakdown of the amino acid phenylalanine. Mutations in the PAH gene lead to a deficiency in this enzyme, resulting in a build-up of phenylalanine in the body.

What is mirroring chromosomes?
Mirroring chromosomes are a genetic abnormality. This abnormality is caused by an exact duplication of a chromosome segment, including the centromere.
What is the mode of inheritance for phenylketonuria?
Phenylketonuria is an autosomal recessive genetic disorder. This means that an individual must inherit two copies of the defective gene (one from each parent) in order to develop the condition.
How possible is it that a parent can pass phenylketonuria to its offspring?
It is possible for a parent with phenylketonuria to pass the condition to their offspring if both parents are carriers of the PKU gene mutation. In this case, there is a 25% chance that their child will inherit two copies of the mutated gene and develop phenylketonuria. Genetic testing can provide more information on the risk of passing PKU to offspring.

If human genetic defect that results in the failure to metabolize the amino acid phenylalanine is?
Phenylketonuria (PKU) is a genetic disorder that causes a person to be unable to metabolize the amino acid phenylalanine. This leads to a buildup of phenylalanine in the body, which can be harmful to the brain and nervous system if not managed properly. Individuals with PKU require a strict low-phenylalanine diet to prevent complications.
