Recommendations for Maternal Phenylketonuria (PKU)
The
American Academy of Pediatrics (AAP) recommends the following to manage maternal
phenylketonuria (PKU):1
- All women and girls of childbearing age with
elevated phenylalanine (Phe) levels should be identified and counseled about
the effects that high Phe may have on a
fetus.
- Pregnant women with high Phe
levels should be offered
tests to detect fetal
problems.
- A woman should have a blood
test for PKU if her child has features that suggest the mother had high
Phe levels during pregnancy. For example, her baby may be born
with a very small head (microcephaly) and heart problems.
A woman who has PKU and is considering pregnancy or is pregnant
should:
- Achieve low levels (below 6 mg/dL) of Phe at
least 3 months before conception.2
- Get
tested at least once a week.
- Receive adequate nutrition.
- Be offered genetic counseling before and during pregnancy.
