In untreated cases, infants born to untreated women have 93% risk for mental retardation and a 72% risk for microcephaly. Low birth weight, characteristic facial features, or congenital heart disease are other results of untreated pregnancies. This is very serious since these birth defects due to an uncontrolled diet in the mother are separate from the actual inherited condition. Most moms with PKU will not have kids with PKU.
