Babies in Danger
This disease can only be inherited by the parents of the baby who has it. In order for a baby to have PKU, BOTH parents must have a gene to change for PKU. If only one parent has then the baby has a gene to change for PKU, but DOES NOT have PKU. About 1 in 10,000 to 15,000 does a baby inherit PKU in the U.S. per year.
- Cause by mutations In the PAH (Phenylalanine hydroxylase) gene on the long arm of chromosome 12
- Around 500 mutations In the PAH gene have been identified in people with PKU (most of these mutations change single amino acid on PAH)
- PAH is responsible For the conversion of phenylalanine to another amino acid called Tyrosine.
- Treatments include strict diet With limited protein
- People who have PKU need to avoid food with high-protein Including:
- Milk and cheese
- Eggs and nuts
- Beans(including soybeans)
- Chicken, beef, and pork
- Fish and peas
- The U.S. Food and Drug Administration (FDA) has approved the drug Sapropterin Dihydrochloride (Kuvan) for the treatment of PKU
