Cerebrocostomandibular syndrome (CCMS) is a rare autosomal dominant multiple malformation disorder characterized by posterior rib gaps and Pierre Robin sequence (micrognathia, glossoptosis, and cleft palate). Affected patients often have respiratory difficulties, associated with upper airway obstruction, reduced thoracic capacity, and scoliosis. Key radiological findings are of a narrow thorax, multiple posterior rib gaps, and abnormal costo-transverse articulation. Mortality is 35%-50% in the first year of life and death is due to respiratory failure. However, general development progresses well once the initial respiratory problems are survived. Specific mutations in SNRPB, which encodes components of the major spliceosome, have been found to cause CCMS.
