Neonatal Phenylketonuria

Usually detected through newborn screening, neonatal phenylketonuria is the form of this inherited metabolic disorder that is identified in the first days of the newborn's life.

What it involves: The baby's body cannot correctly transform phenylalanine, a dietary amino acid, which causes it to build up and can affect development if not addressed in time.

Importance of screening: The test done shortly after birth makes it possible to identify the condition early, when care measures are most timely.

Which specialist handles it? The pediatrician assesses the newborn and interprets the screening results, with support from metabolism specialists when needed; if a result is abnormal, the sensible thing is to see them to guide the next steps.
