Untreated phenylketonuria in pregnant women can lead to all of the above - increased risk of heart defects in the infant, infants with microcephaly, and severe mental retardation in children. Phenylketonuria is a genetic disorder that affects the body's ability to break down an amino acid called phenylalanine. If left untreated, phenylalanine can build up in the blood and cause damage to the brain and other organs.
