Question
Can a newborn with phenylketonuria be cured?
Answer
Phenylketonuria (PKU) is a genetic disorder caused by a deficiency in phenylalanine hydroxylase, which leads to the inability of phenylalanine to be normally converted into tyrosine. This results in the accumulation of phenylalanine in the body, affecting the development of the nervous system. Currently, there is no cure for PKU, but strict low-phenylalanine dietary control can help reduce symptoms and maintain a normal quality of life. Patients need to adhere to dietary control for life and regularly monitor blood phenylalanine levels to ensure they remain within a safe range. Additionally, early diagnosis and treatment are crucial for minimizing the impact of PKU on patients.
