We describe two boys with the cerebro-costo-mandibular syndrome (CCMS). Both patients presented with Pierre Robin anomaly and respiratory insufficiency and died 12 hours and 10 months after birth. The first boy had muscular hypotonia, severe micrognathia, glossoptosis, short palate, preauricular tag, paraumbilical fibroma, and a small and narrow thorax. His chest roentgenographs showed marked hypoplasia of the first to tenth rib, multiple posterior rib-gaps in the only four ossified ribs. Tracheomalacia and stenosis of the left ureter was observed during autopsy. No structural cerebral anomalies were observed. Respiratory distress necessitated a tracheostomy in the second boy. He had severe micrognathia with glossoptosis and a cleft soft palate were noted. His chest roentgenograph showed a bell-shaped, small thorax with multiple dorsal rib-gap defects. CCMS is a rare disorder often associated with Pierre Robin anomaly. Chest roentgenographs show the typical posterior rib-gap defects, which are quite variable. CCMS usually occurs as an isolated event in a family. Of 41 reported families four reports describe horizontal and two describe vertical transmission of CCMS. This might imply genetic heterogeneity with autosomal recessive and autosomal dominant inheritance. Inter- and intrafamilial expression is variable. Careful family studies are necessary before genetic counseling is given.
