Overview By Mayo Clinic Staff. Phenylketonuria (fen-ul-ke-toe-NU-re-uh), also called PKU, is a rare inherited disorder that causes an amino acid called phenylalanine to build up in your body. PKU is caused by a defect in the gene that helps create the enzyme needed to break down phenylalanine. Without the enzyme necessary to process phenylalanine, a dangerous buildup can develop when a person with PKU eats foods that are high in protein.

Phenylketonuria Causes and symptoms. PKU symptoms are caused by alterations or mutations in the genetic code for the PAH enzyme. Mutations in the PAH gene prevent the liver from producing adequate levels of the PAH enzyme needed to break down phenylalanine. The PAH gene and its PKU mutations are found on chromosome 12 in the human genome.

Newborn Screening for inherited metabolic disorders; news and views Phenylketonuria (PKU), one of the most commonly screened metabolic disorders, can readily and reliably be detected by MS/MS. It is an autosomal recessive disorder, most commonly caused by a mutation in the gene coding for phenylalanine hydroxylase.

What is PKU? Phenylketonuria (PKU) is a rare inherited condition in which there is a build up of phenylalanine in the body.KU is a treatable condition. Phenylalanine is found in the protein part of the food we eat. The treatment is a low protein diet. This means that high protein foods such as meat, cheese, poultry, eggs and milk are not permitted.

Phenylketonuria Phenylketonuria (PKU) is characterized by a person's inability to metabolize the amino acid phenylalanine.If the body can not process part of the protien phenylalanine (phe) then it can cause severe brain damage, skin disorders, behavioral problems, heart defects or even mental retardation.enetic Testing. The phenylalanine tolerance test is one form of genetic testing for PKU. It is performed by giving a person a measured amount of phenylalanine and the concentration of phenylalanine in the blood plasma is measured.

Phenylketonuria (PKU) Mutations in the PAH gene cause phenylketonuria. The PAH gene provides instructions for making an enzyme called phenylalanine hydroxylase. This enzyme converts the amino acid phenylalanine to other important compounds in the body.f PKU is not treated, phenylalanine can build up to harmful levels in the body, causing intellectual disability and other serious health problems. The signs and symptoms of PKU vary from mild to severe. The most severe form of this disorder is known as classic PKU.

Phenylketonuria (PKU) Home / Birth Defects & Disorders / Phenylketonuria (PKU) Phenylketonuria (PKU) is a metabolic disease caused by a genetic mutation. This disease used to be very difficult to diagnose, but for the last 40+ years, a PKU test has been a part of the neonatal screening process in the United States.

What is Phenylketonuria (PKU)? - Definition, Symptoms & Treatment The disease is called phenylketonuria, or PKU. In this disease, people have a rare metabolic defect in which they cannot break down the amino acid phenylalanine.

Newborn babies with PKU are given a special diet low in phenylalanine.epending on the level of phenylalanine and tolerance for phenylalanine in the diet, PKU is classified into two different types: classic, which is the severe form, and moderate. Therefore, each patient needs an individualized treatment plan.

Phenylketonuria (PKU) Classic PKU, the most severe form of the disorder, occurs when phenylalanine hydroxylase activity is severely reduced or absent. People with untreated classic PKU have levels of phenylalanine high enough to cause severe brain damage and other serious medical problems.Mutations in the PAH gene that allow the enzyme to retain some activity result in milder versions of this condition, such as variant PKU or non-PKU hyperphenylalaninemia.f PKU is not treated, phenylalanine can build up to harmful levels in the body, causing intellectual disability and other serious health problems. The signs and symptoms of PKU vary from mild to severe. The most severe form of this disorder is known as classic PKU.
