Phenylketonuria PKU

It is an inherited disease in which the body cannot metabolize an amino acid called phenylalanine. Normally phenylalanine is metabolized and converted into tyrosine, another amino acid, but if it stays as phenylalanine, there will be too much of it, and high levels of phenylalanine are harmful to the brain. Following the prescribed diet for PKU is a lifelong endeavor that requires a lot of support from family and your health care provider. If your child is able to strictly follow the diet and supplement regimen, he should be able to live a full, active life. Our dedicated team of physicians, nutritionists, nurses, laboratory technicians, social workers and psychologists are committed to helping children with this highly treatable condition. PKU requires life-long care, and our multidisciplinary team will work with you and your child to help him grow into a healthy adult. For Patients.

Around 1 in 10, babies in Europe are born with the genetic condition, which is screened for during the new born heel prick test. Adults with the condition have to follow treatment and a diet containing almost no protein to minimize symptoms and prevent damage to the brain 1,2. You can find out more about PKU here.

A blood test that measures the phenylalanine in an infant’s blood is enough to help make a PKU diagnosis. Therefore, DNA testing is not necessary. However, if a child tests positive for PKU, health care providers may recommend genetic testing because identifying the type of mutation involved can help guide selection of the most appropriate treatment plan. A DNA test also should be performed on a child if both parents are PKU carriers and the standard newborn blood test does not show the condition.

The test will definitively indicate or rule out PKU, if the disease-causing mutations in the family have been identified. To perform this test, a health care provider takes some cells, either through a needle inserted into the abdomen or a small tube inserted into the vagina. A genetic counselor who understands the risks and benefits of genetic testing can help explain the choices available for testing. The disease causing mutations must have been identified before prenatal testing can be performed.

Phenylketonuria PKU is a rare condition in which a baby is born without the ability to properly break down an amino acid called phenylalanine. Phenylketonuria PKU is inherited, which means it is passed down through families. Both parents must pass on a nonworking copy of the gene in order for a baby to have the condition.

PKU is characterized by absence or deficiency of an enzyme called phenylalanine hydroxylase (PAH), responsible for processing Last Edit Date: 11/01/

PKU is an inherited metabolic disorder that leads to a buildup of the protein phenylalanine Phe , which can cause brain damage and other health problems. Until now, treatment options have included an ultralow-protein diet and the drug sapropterin, which helps only a portion of those who suffer from PKU. This phase of the study included subjects who were already taking pegvaliase because the adverse effects that often occur as a patient begins a pegvaliase regimen would have revealed who was taking the medication and who was taking a placebo.

The trial ran for 8 weeks, and investigators measured blood Phe levels at regular intervals. Throughout the trial, the blood Phe levels of the subjects who continued on their pegvaliase regimens remained at the lower levels they had achieved since starting the drug. The blood Phe levels of those who were taking placebos rose significantly, approaching their baseline levels before beginning treatment.

One of the most difficult obstacles that patients with PKU face is a severe restriction on their diet, with high-protein foods such as meat, fish, eggs, cheese, beans, and nuts generally off-limits. Although [sapropterin]-responsive patients have a lowering of their blood phenylalanine level and an increase in their tolerance of natural protein in the diet, they are rarely able to consume a completely normal diet.
