What is the life expectancy of a person with phenylketonuria?

PKU does not shorten life expectancy, with or without treatment. Newborn screening for PKU is required in all 50 states.

Do you outgrow PKU?

A person with PKU does not outgrow it and must stay on the diet for life.

How does phenylketonuria affect the brain?

PKU affects the brain. When neurotransmitters are not made in the right amounts, the brain cannot function properly. High blood Phe levels can cause disruptions in neurotransmitters like serotonin and dopamine, which are important for mood, learning, memory, and motivation.

How do you know if your baby has PKU?

PKU signs and symptoms can be mild or severe and may include: A musty odor in the breath, skin or urine, caused by too much phenylalanine in the body. Neurological problems that may include seizures. Skin rashes (eczema)

What does PKU smell like?

If PKU is untreated, or if foods containing phenylalanine are eaten, the breath, skin, ear wax, and urine may have a “mousy” or “musty” odor. This odor is due to a buildup of phenylalanine substances in the body.

How is PKU passed on?

PKU is passed on to children when each parent has 1 mutated gene. This means that neither parent has any symptoms of PKU, but both are carriers of the faulty gene. PKU is an autosomal recessive disease. This means that a child needs to inherit 1 faulty gene from each parent to show signs of the disorder.

Is PKU life threatening?

Is PKU a life threatening disease? No. PKU is a slowly progressive disease that does not cause acute symptoms. During the first months of life it is completely asymptomatic and can only be detected by population screening determinations.

What does PKU test for in newborns?

A phenylketonuria (PKU) test is done to check whether a newborn baby has the enzyme needed to use phenylalanine in his or her body. Phenylalanine is an amino acid that is needed for normal growth and development.

How does PKU cause mental retardation?

Mutations in the PAH gene can cause phenylketonuria (PKU), a disorder that can change cells in the brain. The faulty protein allows dangerously high levels of phenylalanine to accumulate in the brain, poisoning the cells. If a person with PKU consumes too much phenylalanine, the build-up can cause mental retardation.

How does phenylketonuria affect the body?

Phenylketonuria (PKU) is a treatable disorder that affects the way the body processes protein. Children with PKU cannot use a part of the protein called phenylalanine. If left untreated, phenylalanine builds up in the bloodstream and causes brain damage.
