Maternal phenylketonuria.
Pregnant women with untreated phenylketonuria (PKU) with blood phenylalanine levels greater than 1200 mumol/L usually give birth to offspring with congenital birth defects, including microcephaly, cardiac defects and mental retardation. According to Mabry and Levy, hyperphenylalaninaemic (HPA) women with blood phenylalanine levels between 600 and 1200 mumol/L also have an increased risk to their offspring. To study this problem further, the National Institute of Child Health and Human Development has established a collaborative study for 7 years to elucidate a proper treatment programme for these women.
