Question
Can a 45-day-old baby with phenylketonuria be treated?
Answer
Phenylketonuria is an amino acid metabolism disorder that can be treated with dietary therapy, with earlier treatment leading to better outcomes. Infants can be fed with specially formulated low phenylalanine formula milk, and during infancy, they should mainly consume low-protein foods such as starches, vegetables, and fruits. Dietary control should be maintained at least until after puberty.
