Why is it called phenylketonuria?
Følling obtained urine samples from the children and, after many tests, he found that the substance causing the odor in the urine was phenylpyruvic acid. The children, he concluded, had excess phenylpyruvic acid in the urine, the condition which came to be called phenylketonuria (PKU).
Who is affected by PKU?
In the United States, PKU is most common in people of European or Native American ancestry. It is much less common among people of African, Hispanic, or Asian ancestry.
What type of genetic disorder is PKU?
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.
What is PKU diet?
The diet for PKU consists of a phenylalanine-free medical formula and carefully measured amounts of fruits, vegetables, bread, pasta, and cereals. Many people who follow a low phenylalanine (phe) food pattern eat special low protein breads and pastas.
How is PKU transmitted?
PKU is inherited from a person’s parents. The disorder is passed down in a recessive pattern, which means that for a child to develop PKU, both parents have to contribute a mutated version of the PAH gene. If both parents have PKU, their child will have PKU as well.
How is PKU diagnosed?
PKU can be easily detected with a simple blood test. All states in the United States require a PKU screening test for all newborns as part of the newborn screening panel. The test is generally done by taking a few drops of blood from the baby before the baby leaves the hospital.

Where is PKU located?
Phenylketonuria (commonly known as PKU) is an inherited disorder that increases the levels of a substance called phenylalanine in the blood. Phenylalanine is a building block of proteins (an amino acid ) that is obtained through the diet. It is found in all proteins and in some artificial sweeteners.
What is PKU formula?
PKU formula is a special blend of amino acids that provides protein without the amino acid phenylalanine (fen-el-al-a-neen) or PHE (fee). Often, formula also contains carbohydrate, fat, vitamins and minerals to help meet your nutritional needs. Some formulas contain a unique ingredient called glycomacropeptide (GMP).
Is PKU curable?
There is no cure for PKU, but treatment can prevent intellectual disabilities and other health problems.
How can PKU be treated?
The main treatment for PKU is a low-protein diet that completely avoids high-protein foods (such as meat, eggs and dairy products) and controls the intake of many other foods, such as potatoes and cereals.
What is the PKU meaning in medical terms?
Phenylketonuria (PKU) is a rare condition in which a baby is born without the ability to properly break down an amino acid called phenylalanine.
What does PKU stand for?
PKU is a rare inherited condition. PKU stands for phenylketonuria. People with PKU cannot. use protein in the usual way. Protein is made up of amino acids, one of which is. Phenylalanine or ‘Phe’ for short. In PKU, the enzyme which breaks down Phe is absent or. present in very small amounts.
Does PKU cause mental retardation?
Damage from a buildup of phenylalanine can begin within the first month of life and, if undetected and/or untreated, PKU results in severe mental retardation, hyperactivity, and seizures. PKU affects about 1 baby in every 10,000 or 15,000 births.
Is there a cure for PKU?
There is no cure for PKU, but treatment can prevent intellectual disabilities and other health problems. A person with PKU should receive treatment at a medical center that specializes in the disorder. (Visit the Resources and Publications section for ways to locate a center.)
