how do they get it?

PKU is inherited in an autosomal recessive pattern. This means both parents must pass on a defective version of the gene PAH for their child to inherit the disorder.


It is rare in the United States—just one in every 10,000 to 15,000 newborns will have PKU.



life expectancy

PKU does not shorten life expectancy, with or without treatment.

treatment

People with PKU need to follow a diet that limits foods with phenylalanine. The diet should be followed carefully and be started as soon after birth as possible. In the past, experts believed that it was safe for people to stop following the diet as they got older. However, they now recommend that people with PKU stay on the diet throughout their lives for better physical and mental health.1,2


It is especially important for a pregnant woman with PKU to strictly follow the low-phenylalanine diet throughout her pregnancy to ensure the healthy development of her infant.3


People with PKU need to avoid various high-protein foods, including:
