What are the effects of pheylketonuria in pregnancy?

Depends: Women with pku can have healthy children as long as they are aware of and maintain strict adherence to their low phenylalanine diet throughout their pregnancy. It is well known that women with poorly controlled pku during a pregnancy put their baby at risk for development problems, heart problems and other structural problems. You really have to talk to your doctor before you get pregnant.

Depends: If you are an infant with the genes to develop pku , your unaffected mother will cleanse your fetal blood through her body & you will start out normal. If you are a pku mom who is not on a strict diet during pregnancy, expect a baby born with neurologic damage, a smaller head, & likely a heart defect even if baby has only one pku gene.
