As initially reported, the syndrome consisted mainly of cleft palate and congenital heart defect. The phenotype was later expanded to include brachycephaly, midfacial hypoplasia, broad nasal bridge, highly arched palate, mandibular prognathism, malformed ears, short hands, mental retardation, and other less constant abnormalities.,MSH: Complex neurobehavioral disorder characterized by distinctive facial features (FACIES), developmental delay and INTELLECTUAL DISABILITY. Behavioral phenotypes include sleep disturbance, maladaptive, self-injurious and attention-seeking behaviors. The sleep disturbance is linked to an abnormal circadian secretion pattern of MELATONIN. The syndrome is
