Understanding Phenylketonuria: A Genetic Condition with Dietary Restrictions

🧬PKU is a recessive genetic condition that requires two copies of the mutated gene for a person to have the condition.

🍽️People with PKU follow a special diet that restricts phenylalanine intake, avoiding foods high in protein as well as artificial sweeteners.

💉PKU is diagnosed through newborn screening programs, which test for elevated levels of phenylalanine in the blood.

🤰Pregnant women with PKU need to be especially careful with their diet to prevent harm to the developing fetus.

🔬Research in genetics has led to better understanding and treatment options for PKU, improving the quality of life for individuals with the condition.

What causes PKU?

—PKU is caused by a defect in the gene responsible for producing an enzyme called phenylalanine hydroxylase, which is needed to break down phenylalanine.

Is PKU curable?

—PKU is not curable, but it can be managed through a restricted diet that limits phenylalanine intake.

Can individuals with PKU have children?

—Yes, individuals with PKU can have children, but they need to carefully manage their diet during pregnancy to prevent harm to the fetus.

What are the consequences of untreated PKU?

—Untreated PKU can lead to intellectual disabilities, developmental delays, and other neurological problems.

Can a person with PKU ever stop following the diet?

—In some cases, individuals with PKU may be able to relax the dietary restrictions as they get older, but this should be done under the guidance of a healthcare professional.
