There are many different symptoms that may indicate the presence of<unk> . Patients typically have a smaller than normal skull, eyes, and mouth, termed microcephaly, microphthalmia, and microstomia. The eyes themselves may be closely separated (hypotelorism) or fused (cyclopia). Infants affected by<unk>  often have a variety of abnormalities in the bones of the forearm, hand, and foot (called pre-axial limb defects), including small or absent thumbs, small or absent big toe, small hands, and various malformations of the radius (the main bone in the forearm). Other associated symptoms include anal atresia, in which an infant is born without an anus, atrial septal defect (a hole between the top two chambers of the heart), ventricular septal defect (a hole between the bottom two chambers of the heart), and ambiguous genitalia. During pregnancy, too much amniotic fluid may be present, a condition called polyhydramnios.
