Question
I don’t know what’s going on, but my child has been acting up recently, crying and fussing all the time. We’ve gone to the hospital and had checks done, but nothing seems to help. What are the characteristic symptoms of phenylketonuria?
Answer
The baby’s urine has no odor, which cannot rule out the possibility of phenylketonuria. If the hospital suspects phenylketonuria, further detailed examinations are needed to confirm the diagnosis. DNA testing can be conducted, and the results of genetic testing are more accurate. Phenylketonuria is a common genetic disorder characterized by amino acid metabolism abnormalities, and it is best to have the baby undergo further detailed examinations to clarify the condition. Early treatment can reduce the interference of the disease on the baby.
