Question
The twin daughters were born 35 days ago and are said to be suspected of having phenylketonuria. After one retest, the older one’s index dropped to 2.5, the younger one’s to 2.4, and the younger one’s to 2.1. Want to ask if it is phenylketonuria?
Answer
Phenylketonuria is a common metabolic disorder caused by a deficiency in phenylalanine hydroxylase, leading to the inability of phenylalanine to be normally metabolized and accumulating in the body, causing damage to the nervous system. For infants, nutritional management can be achieved through the intake of starches, vegetables, and fruits.
