ICD-10 Diagnosis Code E70.0 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.he most severe form of this disorder is known as classic PKU. Infants with classic PKU appear normal until they are a few months old. Without treatment, these children develop permanent intellectual disability. Seizures, delayed development, behavioral problems, and psychiatric disorders are also common.

- The genetics of PKU. Genes are present in every cell in the body. They provide the blueprint for each trait we have, such as eye color and height. Genes also carry the instructions to make the enzymes our bodies need to break down amino acids such as Phe into building blocks.or a person to have PKU, both the mother and the father must pass on the mutated phenylalanine hydroxylase (PAH) gene. Each parent is a “carrier” because he or she carries one copy of the mutated, disease­–causing gene and one copy of the nonmutated gene. People who are carriers of the PKU gene have no known symptoms.

Genetic Abnormalities Involved in PKU: A Guide to Phenylketonuria slide 2 of 5. Phenylketonuria (PKU) Genetics: Mutation of the PAH Gene Phenylketonuria is caused by a mutation of the phenylalanine hydroxylase (PAH) gene which is found in the q arm of chromosome 12. The PAH gene gives specific instructions for the production of the enzyme phenylalanine hydroxylase that converts phenylalanine to tyrosine.

Back to my PKU webpage Phenylketonurics is the term used to refer to people that have the metabolic disorder Phenylketonuria, or PKU for short. So-kind of like how the word diabetics refers to. that have diabetes, phenylketonurics refers to the. that have phenylketonuria. I myself, am one of these phenylketonurics and the warning on diet soda cans is included merely to inform people like me that the product contains the synthetic chemical. .

Phenylalanine The genetic disorder phenylketonuria (PKU) is the inability to metabolize phenylalanine because of a lack of the enzyme phenylalanine hydroxylase. Individuals with this disorder are known as phenylketonurics and must regulate their intake of phenylalanine. A (rare) variant form of phenylketonuria called hyperphenylalaninemia is caused by the inability to synthesize a cofactor called tetrahydrobiopterin, which can be supplemented.

- Classical PKU is caused by a deficiency of the enzyme phenylalanine hydroxylase (PAH). Over 70 different mutations on the PAH gene found on Chromosome 12 have been found to cause the almost complete absence of PAH as seen in PKU patients. PKU patients deficient in PAH are unable to metabolise the amino acid phenylalanine leading to an accumulation of phenylalanine and it's metabolites within the body. PKU is an example of an autosomal recessive disorder.

Conditions Classic Phenylketonuria Phenylketonuria (PKU) is a condition in which the body cannot break down one of the amino acids found in proteins. PKU is considered an amino acid condition because people with PKU cannot break down the amino acid called phenylalanine. If left untreated, PKU can cause brain damage or even death.However, if the condition is detected early and treatment is begun, individuals with PKU can lead healthy lives.KU is considered an amino acid condition because people with PKU cannot break down the amino acid called phenylalanine.

phenylketonuria 2 Protein Supplement People without PKU get all the protein they need from the food they eat. Because protein intake is low in the diet for PKU, a protein supplement is needed to make up what is missing from not eating foods high in protein.For people with PKU the protein supplement is essential.rotein is made up of building blocks called amino acids. Phenylketonuria (PKU) is a condition in which the body is unable to break down one of the protein building blocks from the diet; the amino acid called phenylalanine (phe). In PKU the phe cannot be metabolised normally and builds up in the blood and tissues.

Learning About Phenylketonuria (PKU) Newborn screening has been used to detect PKU since the 1960's. As a result, the severe signs and symptoms of PKU are rarely seen. Top of page. What are the symptoms of PKU? Symptoms of PKU range from mild to severe. Severe PKU is called classic PKU. Infants born with classic PKU appear normal for the first few months after birth. However, without treatment with a low-phenylalanine diet, these infants will develop mental retardation and behavioral problems.

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.

- In order for the body to use protein from the food we eat, it is broken down into smaller parts called amino acids. Special 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.
