Phenotypes
  • prenatal and postnatal growth retardation, low birth weight, mild to moderate intellectual deficit, psychomotor retardation, poor speech, seizures, behavioral problems such as hyperactivity and impulsiveness. Frequent craniofacial abnormalities include microcephaly, high and narrow forehead, broad nasal bridge, epicanthic folds, high arched palate, short neck and low set unusually shaped ears. Furthermore congenital heart defects (atrioventricular, septal defects, pulmonary stenosis), congenital diaphragmatic hernia and in boys cryptorchidism and hypospadias have been frequently reported.
