3 doctors agree

In brief: No

PKU is a genetic disease that you are born with.
Newborn screening helps to diagnose this disease and guides the treatment. Having it diagnosed later in life leads to more problems. A special diet low in phenylalanine is the treatment. During pregnancy it is particularly important.

In brief: Never

The metabolic defect of PKU is present in the fetus, but is inconsequential because the fetus does not consume or process food.
Soon after the newborn starts feeding (24hr) the blood levels of phe will be elevated. By age 3 or so untreated kids have developmental delay and some have seizures.There are mild forms of hyperphenylalaninemia but this is not PKU.,
