Does PKU affect immune system?

How does PKU affect the brain?

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.

What triggers phenylketonuria?

Causes of phenylketonuria PKU is an inherited condition caused by a defect in the PAH gene.

How does PKU affect the body?

A. 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.
