Does PKU shorten your life?
PKU does not shorten life expectancy, with or without treatment. Newborn screening for PKU is required in all 50 states.
Do people with PKU have a normal life?

Why is phenylalanine build up bad?
A dangerous buildup of phenylalanine can develop when a person with PKU eats protein-rich foods, such as milk, cheese, nuts or meat, and even grains such as bread and pasta, or eats aspartame, an artificial sweetener. This buildup of phenylalanine results in damage to nerve cells in the brain.
Can amniocentesis detect phenylketonuria?
An enzyme assay or genetic testing can determine if parents carry the gene for PKU. Chorionic villus sampling or amniocentesis can be done during pregnancy to test the unborn baby for PKU.
Is PKU more common in males or females?
Each year 10,000 to 15,000 babies are born with the disease in the United States and Phenylketonuria occurs in both males and females of all ethnic backgrounds (although it is more common in individuals of Northern European and Native American heritage.)
Why can PKU not be cured?
There currently is no cure for PKU, but the condition is controllable through proper diet and supplements. What kinds of diets do children with PKU need to adopt?

Handsome Devil actor Mark Lavery told RTE.ie that he was born with PKU (Phenylketonuria), a rare inherited disorder that causes an amino acid called phenylalanine to build up in the body.
How is phenylalanine toxic to the brain?
The high plasma phenylalanine concentrations increase phenylalanine entry into brain and restrict the entry of other large neutral amino acids. In the literature, emphasis has been on high brain phenylalanine as the pathological substrate that causes mental retardation.
What is phenylketonuria (PKU)?
Phenylketonuria (PKU) is a genetic metabolic disorder that increases the body’s levels of phenylalanine. Phenylalanine is one of the building blocks (amino acids) of proteins.
What happens if Phenylketonuria is left untreated?
In this NCATS Video Profile, Jennifer Payne discusses living with phenylketonuria (PKU). Left untreated, PKU results in psychological disorders, neurological deterioration, mental illness and brain damage. Dietary management and access to medical foods are a critical part of PKU care.
What are the treatment options for phenylketonuria?
Treatment for PKU normally involves a phenyalanine-restricted diet that is monitored carefully. Some children and adults with PKU may be helped by the medication sapropterin in combination with a low-phenylalanine diet. Adults with high phenylalanine levels despite treatment may be helped by the medication pegvaliase.
How does phenylalanine affect children with PKU?
Babies born to mothers who have PKU and uncontrolled phenylalanine levels (women who no longer follow a low-phenylalanine diet) have a significant risk of intellectual disability because they are exposed to very high levels of phenylalanine before birth. These infants may also have a low birth weight and grow more slowly than other children.
